Technical data sheet for the WIKA BLR-S reed sensor used for continuous liquid level measurement in bypass level indicators.
The WIKA BLR-S reed sensor is designed for the continuous monitoring and recording of liquid levels in connection with transmitters. It operates on the float principle using magnetic transmission, where a permanent magnet actuates reed contacts through the walls of the bypass chamber and sensor tube. The sensor is suitable for various industries including chemical, petrochemical, natural gas, offshore, shipbuilding, and power generation.
