With the acoustic sensors for pump monitoring, SITRANS DA, even the smallest leakages on delivery valves of oscillating positive displacement pumps (e. g. piston pumps) can be detected by measuring cavitation. SITRANS AS100 is an acoustic sensor used for solids flow detection. The SITRANS AS100 can be connected to a SITRANS CU02, which processes signals from the sensor, providing relay and analog outputs for connection into a process, or it can be connected directly to a PLC analog input.
