Oil health check
19 February 2014
There are any number of sources of contamination in oil, but no matter where particles come from, their presence in hydraulic systems interferes with the ability of the hydraulic fluid to lubricate and causes wear to the components.
To measure the extent of contamination by solid particles, ifm electronic has launched the LDP, designed for the analysis of particle concentration for trend monitoring and display of cleanliness levels according to ISO 4406:99 or SAE AS4059E.
Typical particle sizes found in hydraulic oils range from 4 to 14µm, 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.
Not only does the LDP have a display, it 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.
