ifm efector LDP100 optical particle monitor

The LDP100 optical particle monitor measures the degree of cleanliness or the level of contamination in fluids. Compatible media are mineral oils, ester oils and biodegradable oils.

The illuminated back of the LCD display indicates the oil cleanliness level and is divided into sections that show the level of 4, 6, 14 and 21 micron particles within the sample.

The LDP100 operates on a principle of light extinction. The changes to the intensity of a laser beam caused by particles in the medium flowing through the measurement cell are detected by a photodetector. The calibration is made in accordance with ISO11943. If desired, the sample can also be monitored to SAE standards with a press of a button.

On the fluid side, the LDP100 is equipped with two quick-action Minimess connections allowing the unit to be mounted in the oil circuit. The unit is compact and can even be installed on the high-pressure side of a hydraulic powerpack being rated to 420 bar.

Electrically, a stepped analog output shows the value of all levels of cleanliness with an additional solid-state output that can be set to any alarm level. Additionally, there is a full CAN output which enables history and various data to be extracted and displayed. An optional colour LED display can also be fully programmed to display this information remotely, eg, in a control room or a cabin. The electrical connection is installed using a highly waterproof 8-pole M12-plug.
