IFM LI5141 Binary Level Sensor

This binary level sensor uses the capacitive measuring principle and direct contact with media to detect when a set limit level is reached, outputting a switched signal for other process equipment. The sensor will detect media with a dielectric constant >1.8, including hydrous coolants, oils, lubricants, water and media similar to water. Ideal for applications such as monitoring liquid level in tanks, overflow protection in a supply tank for coolant emulsion, leakage monitoring in the overflow vessel of a hydraulic power pack, minimum level monitoring, etc.
