FAQ

What exactly is the task / function of the component?
The sensor detects a physical operating state such as pressure, temperature, position or fill level and uses this to provide an electrical signal for display or control. The signal characteristics must match the control unit and the measuring range.

How do you recognize a defect / typical symptoms?
Typical symptoms are incorrect displays, warning messages, protective shutdowns, starting problems or an implausible measured value despite inconspicuous mechanics. Common causes are signal drift, internal interruption, short circuit or contact corrosion on the connector.

How do you check / test the component?
The supply, ground and output signal are checked with a multimeter or oscilloscope; in the case of passive sensors, the resistance or characteristic curve is also checked. Also relevant are tightness, thread condition, plug lock and mechanical damage to the sensor body.

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

How do you check compatibility?
The OEM number, measured size, thread or installation type, sealing concept, connector pattern and electrical characteristics must be compared. The measuring range, switching point or resistance value must also match the application exactly.
