Electronic Advance Piston Travel Sensor

The DETEQ 81.01.1001 Electronic Advance Piston Travel Sensor is designed for measuring the displacement of the advance piston in rotary diesel pumps such as Bosch VE, Delphi/Lucas DPA, DPC, DPS, and DP200.

It provides an electronic signal proportional to piston movement, allowing the test bench operator to monitor the injection timing advance electronically with high precision.

When connected to DETEQ measuring and simulation systems (DAR25, AR60N, or ERT45R), the displacement can be displayed in either millimeters or angular degrees, depending on the pump type and calibration scale.

Key Benefits
