(see chapter 3. "Specifications")
Constant output signal upon
change in pressure
Mechanical overload caused by overpressure
Replace pressure sensor; if it fails repeatedly,
contact the manufacturer

Mechanical overload caused by overpressure
Replace pressure sensor; if it fails repeatedly,
contact the manufacturer
Signal span varies
EMC interference sources in the environ-
ment; for example, frequency converter
Shield the pressure sensor; cable shield;
remove source of interference
Signal span varies/inaccurate
Operating temperature too high/low
Observe the permissible temperatures
(see chapter 3. “Specifications”)
