Omron K7L Series Liquid Leak Sensor - Plug-In, 12 → 24 V dc 1 Voltage Input PNP

Omron Liquid Leakage Sensor K7L Series. The K7L-AT50 liquid leakage sensor amplifier by Omron can detect a wide variety of liquids ranging from water to chemicals with low conductivity. It internally oscillates AC signals provided to the Sensing Band, protecting it from electric corrosion and ensuring safe operation. There are four sensing ranges available, ensuring detection is suited to the application. The K7L also incorporates a noise canceller circuit that uses a 3-conductor cable, ensuring a high level of noise immunity. Isolation between the power supply circuits and sensing circuits allows for multiple channels to be installed in the same location. Features and Benefits. Inter-electrode resistance detection AC detection method Noise canceller function Multi-channel applications Detection of condensation and liquid leakage at semiconductor production installations Sensing band with excellent chemical resistance Detection of liquid leakage at pipe joints for liquid chemical tanks Liquid leakage detection for measuring baths in CMP devices Detection of cleaning fluid level for plating devices Stable detection of liquids with impedances of up to 50 mΩ and common water. Product Application Information. The K7L can be used in a wide range of applications, from semiconductor production installations to food-processing equipment.
