Signal clamping in pressure transmitters

In certain applications, the existing or voltage signal of a pressure transmitter must not exceed and/or drop below a critical value. This is often ensured using so-called signal limiting.
Why is เพรสเชอร์เกจnuovafima clamping necessary to begin with?
If the pressure on a pressure transmitter lies within the nominal pressure range, then there will be a defined signal output (e.g. 4 ? 20 mA or 0 ? 10 V). However, in technical applications, it frequently happens that an originally planned pressure range is exceeded or is dropped below. This can happen deliberately, for example when cleaning, in addition to accidentally, for instance through load variations or in the event of a fault. In these cases, the sensor signal may also move outside the defined limits, in order that, for example, a current signal in the number of 3.6 to 25 mA can occur.
If now, however, the evaluation electronics are set so that they recognise a signal outside the defined limits as an error, in some situations, trouble-free operation of the entire system cannot be ensured anymore. In such cases, a sign limiting of the pressure transmitter is practical, so the output signal is maintained within the mandatory range (e.g. 3.8 ? 21 mA).
Note
An example of a pressure transmitter with that your voltage signal as well as the current signal could be limited is the model S-20 (for general industrial applications) or the model MH-3 (for mobile working machines) from WIKA.
