250039-910 Sullair Pressure Sensor Replacement

250039-910 Sullair Pressure Sensor Replacement Description

The 250039-910 is a Sullair air compressor pressure sensor (pressure transducer) designed to monitor compressed-air pressure and send an electrical signal to the compressor controller.

According to the available product information, the sensor has a 0–200 psi measurement range and a 1–5 VDC output. It is referenced for Sullair LS20 and LS25 screw air compressors.

The controller uses the pressure signal to regulate compressor loading and unloading and maintain the required working pressure. Before ordering, confirm the compressor model, sensor specifications, and original part number against your existing component.

250039-910 Sullair Pressure Sensor Replacement Function

The 250039-910 pressure sensor converts the compressed-air pressure it detects into a 1–5 VDC electrical signal that the compressor controller can interpret.

The controller uses this pressure information to determine when the compressor should load or unload and to regulate system pressure. A properly functioning pressure sensor therefore provides an important input for the compressor’s automatic pressure-control system.

250039-910 Sullair Pressure Sensor Replacement Solutions

01 — Incorrect Pressure Feedback Affects Loading and Unloading

A pressure sensor that sends an inaccurate signal can cause the controller to load or unload the compressor at the wrong pressure point. Replacing it with the correct 250039-910 specification restores the pressure feedback required for normal control.

02 — Unstable Pressure Can Affect Compressor Operation

When the pressure signal is erratic or incorrect, the controller may struggle to maintain the required working pressure. Replacing a faulty sensor helps restore consistent pressure monitoring and control.

03 — Pressure Alarms or Trips Can Interrupt Operation

A failed transducer may produce a missing, abnormal, or incorrect signal, potentially resulting in pressure-related alarms or shutdowns. Confirming the sensor range and output signal before replacement helps reduce the risk of installing an incompatible component.

04 — Incorrect Sensor Specifications Can Cause Compatibility Problems

A pressure sensor is not interchangeable simply because it has a similar appearance or application. The 0–200 psi range, 1–5 VDC output, compressor model, and original part number should be checked before ordering.
