ACOUSTIC SENSORS

Acoustic sensors for pump monitoring
Even the smallest leakages on delivery valves of oscillating positive displacement pumps (e. g. piston pumps) can be detected by measuring cavitation. The acoustic diagnostic device SITRANS DA400 consists of
cavitation sensors and an analyzer unit which supplies the sensors with electrical energy and detects, filters
and evaluates the measured signal and outputs an alarm signal on exceeding a defined limit value.
