Signal clamping	The range of the output signal can be limited. For this purpose, a lower and an upper signal threshold are defined in the sensor electronics. If the output signal reaches these threshold values, the sensor outputs a defined, constant signal value.Therefore, in operation, unwanted pressure or signal ranges are filtered out.

Output signal

Diagnostic function	Permanent errors in the sensor electronics and temporary system overpressures can be output through defined constant output signals.A permanent error signal signifies a sensor defect and cannot be reset.The temporary error signal is reset as soon as the system pressure once again lies under the error threshold. In the application, one can therefore realise an efficient system diagnosis.
