2.1 Overview

2.2 Signal clamping

The output signal of a pressure sensor can be above the nominal maximum signal
value, if no signal clamping has been set. Likewise, the output signal can also be below
the nominal minimum signal value. This undefined condition can cause an error in
the machine (software) of the customer. Signal clamping limits the output signal to a
minimum or maximum value which is to be defined by the customer.

2.3 Diagnostic function

By means of the output signal, fault conditions can be detected and evaluated via
software. Thus it is possible to differentiate between permanent and temporary faults.
