025-28678-006 Pressure Transducer Danfoss

In terms of core functions, this sensor is the key component for pressure detection of the unit. It is usually installed in the refrigerant pipeline, the inlet and outlet of the compressor, or the lubricating oil return circuit, collecting the system pressure in real time and converting it into standard analog signals for transmission to the unit controller. This provides precise data support for pressure closed-loop regulation and fault protection logic, helping the controller achieve control functions such as load regulation, high and low pressure alarms, and surge prevention. It is a fundamental detection component for ensuring the stability of the unit's operating parameters.

In terms of product features, it adopts Danfoss's mature piezoresistive sensing technology, with high measurement accuracy within the entire working temperature range and small zero drift. The long-term operating data is highly consistent. The stainless steel sensing chamber and integrated sealing structure can withstand the long-term erosion of refrigerant and refrigerating oil, and are suitable for complex working conditions of the refrigeration system with high pressure and temperature fluctuations. It has a 5V low-voltage power supply and standardized 0.5-4.5V output signal, fully compatible with York's original control interface. Replacements of the same model do not require additional calibration or debugging. At the same time, it has excellent anti-electromagnetic interference and anti-mechanical vibration performance, and can operate stably and reliably in the electrical control environment of the machine room.
