The units can for instance monitor the drop-by-drop dosage of lubricating or rolling oil with up to 30 micro pulses per minute. A switching signal is generated for every detected pulse. The dwell time can be adjusted in a 0.5…10 s range. An integrated LED display shows the current flow status.

Manufactured from stainless steel and PBT, the robust sensors are IP67-protected and withstand pressures up to 10 bar. Suitable for media temperatures between +10 and +60 °C, they are operated with 24 V DC.

Requiring little space, the compact units are fitted into pipes via a tube fitting or a G¼ thread and connected by means of an M12 connector.
