Oil particle sensor
24 February 2014
ifm electronic has intrpduced its LDP sensor which is designed specifically for the analysis of particle concentration in oil for trend monitoring and display of the cleanliness levels according to ISO 4406:99 or SAE AS4059E.

Typical particle sizes found in hydraulic oils range from 4 to 14µm; these are within the measuring range of the LDP.
The LDP will cope with various oil types, from mineral and ester oils to biodegradable oils, with temperatures between -10 and 80 °C and dynamic pressures to 420 bar.
It has a display and will provide analogue output (4-20 mA configurable), with a digital alarm output, with digital input to start and stop readings. It also features a data memory for 3000 data records.
There is an interface to CAN for integration into mobile control systems.
