8 Maintenance and fault rectification 8 Maintenance and fault rectification 8.1 Maintenance, cleaning When used in the correct way, no special maintenance is required in normal operation. In some applications, product buildup on the sensor diaphragm can influence the measuring result. Depending on the sensor and application, take precautions to ensure that heavy buildup, and especially a hardening thereof, is avoided. If necessary, the transmitter has to be cleaned.
8 Maintenance and fault rectification In Ex applications, the regulations for the wiring of intrinsically safe circuits must be observed.
