1 A division of the WIKA groupReed sensor , model BLR-SApplications sensor for the continuous level measurement of liquids in bypass level indicators Chemical, petrochemical industry, natural gas, offshore, shipbuilding, machine building, power generating equipment, power plants Process water and drinking water treatment, food and beverage industry, pharmaceutical industrySpecial features Installation of head-mounted transmitters in the connection housing possible Wide variety of different electrical connections, process connections, materials and contact separations Programmable and configurable head-mounted transmitters for 4 .. 20 mA, HART , PROFIBUS PA or FOUNDATION Fieldbus field signals Explosion-protected versions Temperature ranges from -100.

2 +350 CDescriptionThe model BLR reed sensors are used for continuous monitoring and recording of the liquid level in connection with transmitters. They work on the float principle with magnetic transmission (permanent magnet, reed switch and resistance measuring chain) in a 3-wire potentiometer magnetic system built into the float actuates reed contacts, through the walls of the bypass chamber and of the sensor tube, in a resistance measuring chain (potentiometer). The measurement voltage generated by this is proportional to the fill measurementKSR data sheet LM 1 of 7 KSR data sheet LM 07/2017 Reed sensorFor bypass level indicatorsModel BLRfor further approvals see page 3 The resistance measuring chain is made up from reed contacts and resistors soldered onto a PCB.
