Leaks can be detected early and reliably using the capacitive sensors LEAK-500-... and KAS-40-LEAK-PTFE-N from RECHNER. The LEAK sensor can be mounted directly on to the base of a basin or trip tray with or without the attached holder. The measuring field of the sensor is directed to the bottom; however the base will not be detected whether it is made of plastic, glass or even metal. In the case of a leakage the sensor will detect the dripping or running liquid immediately it approaches the active area and gives a switching signal for alarm and action.


Housing and cable of the LEAK sensors are made of PTFE. This makes them ideal for all industries, including the semiconductor and chemical industry. The available variants are for 10?35 V DC supply voltage with NPN- or PNP-Transistor output or NAMUR sensors with ATEX certificate for use in areas with danger of explosion of zones 1/2 or zone 20.
The dimensions are small with 37.5 mm in diameter and 18.8 mm in height. The gap between the sensor and the bottom is just 2.8 mm. The measuring area where the liquid is detected is within this gap at the feet of the sensor.


Capacitive LEAK sensors are a great help to prevent problems caused by liquid leaks of a critical nature.
