Mitsubishi Kakoki Kaisha MM32 Multi-Monitor for SELFJECTOR Oil Purifier
The Mitsubishi Kakoki Kaisha MM32 Multi-Monitor is an integrated sensor display and monitoring unit used with compatible Mitsubishi SELFJECTOR marine oil purifiers / centrifugal separators.
Unlike a simple digital display, the MM32 receives signals from several purifier sensors and presents critical operating values such as oil flow rate, temperature, pressure and rotational speed, while also supporting purifier protection and detection functions.
Mitsubishi SELFJECTOR documentation describes the Multi-Monitor as an integrated detection and display instrument. In the MM32 configuration, it provides the broadest set of monitoring functions among the documented MM12, MM22 and MM32 variants.
The photographed SM MARINE SERVICE™ stock unit is clearly marked:
Manufacturer: MITSUBISHI KAKOKI KAISHA, LTD.
Product: Multi-Monitor
Model: MM32
Application: Mitsubishi SELFJECTOR Oil Purifier
Visible Monitoring Functions:
Flow Rate (L/h) ×10
Temperature (°C)
L. Pressure (MPa)
Revolution (min⁻¹)
H. Pressure (MPa)
Error
This combination of functions makes the MM32 a key monitoring component in compatible automated Mitsubishi purifier systems.
What Is the Mitsubishi MM32 Multi-Monitor?
The MM32 is an electronic monitoring unit that collects operating signals from sensors installed around a Mitsubishi SELFJECTOR purifier.
According to Mitsubishi/Samgong SELFJECTOR documentation, MM32 can monitor:
- Flow rate
- Oil inlet temperature
- Light-liquid outlet pressure
- Bowl / horizontal-shaft revolution speed
- Heavy-liquid or circulation-line pressure
- Leakage condition
- Discharge operation
- Water detection
The monitor therefore allows engineers to view important purifier operating conditions from one integrated panel.
Mitsubishi SELFJECTOR Application
Mitsubishi Kakoki Kaisha is the manufacturer of the Mitsubishi SELFJECTOR centrifugal oil purifier family.
The company's current official SJ-H Series page confirms that its marine oil purifiers use a Multi-display monitor panel for displaying oil flow-through rate, discharge pressure, flow-through temperature and leakage detection.
Mitsubishi also states that its SELFJECTOR products have a major presence in marine applications and that the company has decades of marine equipment experience.
This makes “Mitsubishi Selfjector MM32” one of the most important buyer-search phrases for this unit.
MM32 Display Functions
The faceplate of the photographed MM32 provides direct identification of its major measured values.
Flow Rate – L/h ×10
The MM32 displays the purifier's oil-flow rate.
The faceplate is marked:
Flow rate (L/h)
×10
Flow rate is an important purifier operating parameter because excessive or insufficient throughput can affect separation performance.
Mitsubishi's official SJ-H description confirms that its Multi-display monitor panel provides oil flow-through rate indication.
Temperature Monitoring
The panel includes:
Temp. (°C)
SELFJECTOR documentation identifies this function as the indication of inlet / operating temperature.
Oil temperature is critical to separator performance because viscosity and separation efficiency depend strongly on correct heating of the processing liquid.
An incorrect temperature reading can therefore affect both purifier operation and troubleshooting.
L. Pressure – Light Liquid Pressure
The MM32 front panel is marked:
L. press. (MPa)
SELFJECTOR documentation identifies one of the standard Multi-Monitor values as the light-liquid outlet pressure.
In normal purifier service, this parameter helps engineers monitor the purified-oil discharge condition.
H. Pressure – Heavy Liquid / Circulation Pressure
MM32 adds an important measurement not provided by all lower-function variants.
The front panel is marked:
H. Press. (MPa)
One SELFJECTOR manual table identifies the MM32-specific additional pressure function as heavy-liquid outlet pressure, while another section describes a circulation line pressure sensor for MM32.
For servicing, the exact interpretation should follow the manual for the specific SELFJECTOR generation and automatic-control configuration.
This is one reason engineers should identify not only “MM32” but also the exact purifier model and system.
Revolution / RPM Monitoring
The panel includes:
Rev. (min⁻¹)
MM22 and MM32 configurations support purifier rotational-speed indication according to Mitsubishi SELFJECTOR documentation.
The revolution signal is normally obtained from a dedicated revolution sensor / proximity pickup.
Marine spare-parts records identify:
KH0831001 – Revolution Sensor
for Mitsubishi purifier installations.
This is an important related spare-parts keyword for MM32 users.
Leakage Monitor Function – LM
MM32 supports a Leakage Monitor function, commonly abbreviated LM in Mitsubishi documentation.
This function helps detect abnormal leakage conditions associated with purifier operation.
Mitsubishi's official current SJ-H product page also confirms leakage detection as one of the functions of the Multi-display monitor.
For engineers searching online, useful phrases include:
Mitsubishi purifier leakage monitor
MM32 LM function
Selfjector leakage alarm
Discharge Detector Function – DD
The MM32 also supports the Discharge Detector function (DD).
SELFJECTOR manuals show this function as available on MM22 and MM32 configurations.
This function is related to monitoring the purifier's sludge-discharge operation.
If the purifier control system reports a discharge-related error, the problem may involve the detector, wiring, automatic-control system or monitor—not necessarily the MM32 itself.
Water Detector Function – WD
A major MM32-specific feature is Water Detector (WD) support.
The MM12/MM22/MM32 comparison tables show the water-detection function on the MM32 configuration.
This is particularly relevant to Mitsubishi HIDENS / H-HIDENS systems, where monitoring the separated water phase is an important part of automated purifier operation.
MM12 vs MM22 vs MM32
This distinction is extremely useful for both SEO and replacement sourcing.
Mitsubishi documentation lists several Multi-Monitor configurations.
MM12
Provides basic indication functions such as:
Flow rate
Inlet temperature
Light-liquid outlet pressure
and the applicable leakage-monitor functionality.
MM22
Adds functions such as:
Revolution indication
Discharge Detector
depending on system generation/configuration.
MM32
Adds the most complete function set, including:
Flow rate
Temperature
Light-liquid pressure
Revolution
Additional heavy-liquid/circulation pressure
Leakage Monitor
Discharge Detector
Water Detector
Therefore MM12, MM22 and MM32 must not automatically be treated as interchangeable.
Important Part Number – KH2086320
One of the strongest commercial part-number references associated with the exact model is:
KH2086320 – MULTI-MONITOR, MM32
A marine spare-parts catalogue for Mitsubishi Kakoki Kaisha SJ25HH specifically lists KH2086320 – MULTI-MONITOR, MM32.
For SEO, all these variations should be searchable:
KH2086320
KH 2086320
KH-2086320
MM32 KH2086320
Mitsubishi KH2086320
However, the part number should still be confirmed against the original purifier's spare-parts list before purchase.
Related MM32 Sensors
The Multi-Monitor works together with several sensors installed on the SELFJECTOR.
Mitsubishi manuals identify sensor categories including:
Temperature Sensor
Oil Inlet Pressure Sensor
Oil Outlet Pressure Sensor
Revolution Sensor
MM32-specific pressure/circulation sensor
Marine spare-parts listings provide useful related references such as:
KH0831001 – Revolution Sensor
KH0831002 – Multi-Monitor Pressure Sensor
KH0831003 – Multi-Monitor Temperature Sensor
These are powerful related search keywords because an apparent MM32 failure may actually be caused by one of its external sensors.
Mitsubishi SJ25HH Application
One particularly strong documented application is:
Mitsubishi Kakoki Kaisha SJ25HH
The SJ25HH spare-parts listing includes:
KH2086320 – MULTI-MONITOR, MM32.
This makes the following queries highly relevant:
SJ25HH MM32
Mitsubishi SJ25HH Multi Monitor
SJ25HH KH2086320
Mitsubishi SJ35HH Application
A Mitsubishi supply list for an SJ35HH installation identifies:
Oil Purifier With Multi-Monitor (MM32)
and includes leakage-monitor, discharge-detector and water-detector functions.
This is another strong and well-supported related application.
Related SELFJECTOR Models
Competitor and spare-parts pages also frequently combine Multi-Monitor searches with Mitsubishi purifier models such as:
SJ10G
SJ15H
SJ25HH
SJ30G
SJ30GH
SJ35HH
SJ50GH
For example, SJ10G/SJ30GH spare-parts lists include Multi-Monitor sensors and MM-series references, while SJ50GH listings mention MM3 Multi-Monitor.
These model names are useful related search keywords.
But they should not be interpreted as proof that the same MM32 hardware is compatible with every listed purifier model.
MM32 and MM3 Are Not Automatically the Same Reference
Older/newer Mitsubishi documentation may use descriptions such as:
MM1 / MM2 / MM3
while other SELFJECTOR manuals use:
MM12 / MM22 / MM32.
For example, separate SELFJECTOR Genius documentation describes an MM-1/MM-2/MM-3 Multi-Monitor family.
These naming families are useful SEO references, but MM3 and MM32 should not automatically be treated as the same hardware or interchangeable unit.
Always use the exact purifier manual, monitor label and part number.
Normal Display Operation
SELFJECTOR MM32 documentation explains that during normal operation the monitor displays primary sensor information including:
Flow rate
Operating / inlet temperature
Light-liquid outlet pressure
while additional readings such as revolution and MM32-specific pressure can be accessed through monitor controls depending on the version.
The photographed MM32 uses indicator lamps beside:
Flow rate
Temp.
L. press.
Rev.
H. Press.
Error
to identify which measured parameter is being displayed.
Common Problems & Troubleshooting
MM32 Has No Display
Check the monitor supply voltage, wiring and purifier control-panel power first.
Do not immediately replace the Multi-Monitor before verifying the incoming supply and connectors.
Flow Rate Reading Is Incorrect
Inspect the flow-measurement system and relevant wiring.
Also verify that actual purifier flow is within the expected operating condition.
A sensor or signal problem can produce an abnormal display even when the MM32 electronics are functional.
Temperature Reading Is Incorrect
Inspect the temperature sensor and cable.
Marine parts references identify KH0831003 as a Mitsubishi Multi-Monitor temperature sensor in related installations.
Pressure Reading Is Incorrect
Check:
Pressure sensor
Pressure line / connection
Sensor wiring
Monitor connection
before replacing the monitor.
The Mitsubishi Multi-Monitor family uses separate pressure sensors for relevant purifier pressure measurements.
Revolution / RPM Is Not Displayed
Inspect the revolution sensor/proximity pickup and its wiring.
A related documented reference is:
KH0831001 – Revolution Sensor.
ERROR Indicator Is Active
The MM32 is capable of displaying sensor abnormalities/errors.
Record the displayed error condition before resetting or disconnecting equipment.
Then inspect the related sensor and circuit according to the applicable SELFJECTOR manual.
Leakage Alarm Occurs
Check whether an actual oil leak exists before investigating the monitor.
Then inspect the leakage detection circuit, sensor and associated connections.
Discharge Detector Fault
Inspect purifier discharge operation, detector condition, wiring and automatic-control sequence.
The monitor should not be replaced simply because the discharge function reports a fault.
Water Detection Fault
For MM32/HIDENS applications, inspect the relevant water-detection circuit and purifier operating condition.
The exact procedure depends on the automatic-control arrangement fitted to the SELFJECTOR.
Why MM32 Replacement Requires Careful Matching
The term MM32 identifies an important function level, but replacement selection should also consider:
SELFJECTOR model
Automatic-control system
Part number
Sensor configuration
Connector arrangement
Monitor revision
Existing wiring
The safest RFQ therefore includes clear photographs of the original MM32 and the purifier nameplate.
