Common product malfunctions:
1. Unit reports oil pressure sensor fault; compressor fails to start or load
Internal PCB burnt out or wiring disconnected; no pressure signal transmitted to the main controller; oil pressure interlock prevents unit startup.
2. Oil pressure/differential pressure readings fluctuate continuously; frequent false alarms for oil filter clogging
Connector seal failure allows oil mist to penetrate the PCB, causing erratic signal output; main controller misinterprets data and triggers load reduction due to perceived filter saturation.
3. Slow oil pressure buildup during cold-weather startup; frequent low-pressure warnings
Temperature compensation circuit failure leads to low pressure readings during cold-oil operation; unit repeatedly displays “insufficient oil pressure” alerts.
Heat exchanger clogging goes undetected; high discharge pressure and increased energy consumption
4. Water-side differential pressure measurement failure; no feedback on abnormal pressure differentials; long-term scaling on tube bundles causes a significant drop in heat exchange efficiency.
5. Diaphragm rupture allows medium to penetrate the PCB, burning out the main controller’s 24V signal channel
Corrosion and cracking of the stainless steel diaphragm allow refrigerant oil or water to enter the terminal housing; signal line short-circuit damages the mainboard’s data acquisition port.

Core Product Functions:
1. Monitoring of Lubricating Oil Pressure and Oil Filter Differential Pressure (Core Feature)
Real-time monitoring of oil pump supply pressure and differential pressure across the oil filter. If startup oil pressure is insufficient, the compressor is immediately locked out to prevent bearing burnout due to dry running; a pop-up alert notifies the user to replace the oil filter element if the differential pressure exceeds limits.
2. Water Circuit Differential Pressure Monitoring (Predicts Heat Exchanger Scaling/Water Pump Failure)
High differential pressure indicates evaporator scaling or blockage; low differential pressure indicates insufficient water pump flow. Early scheduling of cleaning and maintenance prevents high-pressure unit overload.
3. Multi-level Oil Pressure Safety Interlock Protection
Delayed alarm and startup inhibition if startup oil pressure falls below the threshold; automatic load reduction protection if operating differential pressure consistently exceeds limits.
4. Stable Measurement Across a Wide Temperature Range (All-Season Operation)
Readings remain drift-free across an oil temperature range of -35°C (cold oil) to 110°C (hot oil), ensuring no false “low oil pressure” alarms during cold-weather startups in northern regions.
5. All-Metal Isolation Structure (Zero Leakage Risk)
Contains no rubber pressure-bearing components; prolonged immersion in refrigeration oil causes no swelling or damage, and the medium cannot seep into the circuit board to cause short circuits.
