41-5781 Pressure Sensor Transducer for Thermo King V-Series Refrigeration Units

41-5781 Pressure Sensor Transducer for Thermo King V-Series refrigeration units. Also replaces 415781 and 415-781. Suitable for applications including V-090, V-100, V-190, V-200, V-250, V-300, V-400, V-500, V-600, V-700 and V-800.

41-5781 Pressure Sensor Transducer for Thermo King

The 41-5781 Pressure Sensor is a replacement pressure transducer designed for Thermo King refrigeration systems. It is also identified by the part numbers 415781 and 415-781. The sensor monitors refrigerant pressure and sends a pressure signal to the refrigeration control system. This helps the system maintain stable cooling performance and supports accurate pressure monitoring.

The 41-5781 pressure transducer fits a range of Thermo King V-Series refrigeration units and selected bus air conditioning applications. Common applications include V-090, V-100, V-190, V-200, V-250, V-300, V-400, V-500, V-600, V-700, and V-800 models. Application coverage can vary by unit configuration, so buyers should verify the part number before ordering.

This pressure sensor uses a 7/16″-20 UNF female thread according to published specifications. One supplier lists its pressure range as 15–515 PSI and identifies it as a discharge pressure sensor for Thermo King equipment.

The sensor provides an important input for refrigeration system control and pressure monitoring. A worn or inaccurate pressure sensor can affect system diagnosis and cooling operation. Replacing the sensor with a correctly matched 41-5781 pressure transducer can help restore reliable pressure monitoring.
