FAQ

What exactly is the purpose/function of this component?
The sensor detects a physical operating condition such as pressure, temperature, position, or liquid level and generates an electrical signal based on this data for display or control purposes. The signal characteristics must be compatible with the control unit and the measurement range.

How can you tell if there’s a defect? What are the typical symptoms?
Typical symptoms include incorrect readings, warning messages, safety shutdowns, startup problems, or an implausible measured value despite the mechanical components appearing normal. Common causes include signal drift, an internal open circuit, a short circuit, or contact corrosion at the connector.

How do you check or test the component?
Check the power supply, ground, and output signal using a multimeter or oscilloscope; for passive sensors, also check the resistance or characteristic curve. Also relevant are leaks, the condition of the threads, the connector lock, and mechanical damage to the sensor body.

When should it be replaced?
The sensor should be replaced if the characteristic curve is clearly incorrect, the signal fails, the housing is damaged, or there is a leak at the measurement point. Preventive replacement is particularly advisable in cases of corroded mounting locations or when maintenance is difficult to access.

How do you check compatibility?
Compare the OEM number, measured variable, thread or mounting type, sealing design, connector configuration, and electrical characteristic curve. The measurement range, switching point, and resistance value must also match the application exactly.
