Ifm’s (Germany) particle monitor LDP100 continuously monitors the contamination of oils. It analyses particle concentration for trend monitoring and offers CAN output.
THE SENSOR DISPLAYS THE CLEANLINESS LEVELS according to ISO 4406:99 or SAE AS4059E. It is encased in an aluminum die-cast housing for operating with pressures of up to 420 bar and features an illuminated graphic display and an intuitive push-button set-up. Its protection level is IP67.
Additionally to the CAN interface, it also includes analog and switching outputs. The sensor monitors the degree of cleanliness or the level of contamination in fluids. Compatible media are mineral oils, ester oils and biodegradable oils. The integrated data memory allows data recording over a longer period for up to 3000 data sets. The LCD display indicates the cleanliness level.
The optical particle monitor operates according to the light extinction principle.
The changes to light intensity of a laser beam caused by particles in the medium flowing through the measurement cell are detected by a photo detector.
The calibration is made in accordance with ISO 11943. On the fluid side the sensor is equipped with two Minimess connections with which the unit can be mounted in the off-line circuit of the oil cycle. The electrical connection is installed using an 8-pole M12-plug. The temperature of the oil can range from -10 °C to 80 °C.
