Level sensing relay MK 9151 varimeter

? According to IEC/EN 60 255, DIN VDE 0435-303

? 3 probe connections for 2-point and 1-point level control

? Also for use as moisture detector

? High interference resistance of the measuring circuit, which is isolated from the mains

? Max. wire length to the probes: 1500 m

? Large setting range: 2 ... 450 k? this permits differentiation between fluid and foam

? Adjustable response and release time delay: 0,2 ... 20 s

? Programmable for open circuit operation (without bridge) or closed circuit operation(bridge X1-X2 or X1-COM)

? For auxiliary voltages of 24 ... 415 V AC or 24 V DC

? Green LED for operation

? Yellow LED for contact position

? 1 or 2 changeover contacts

? Also available with sealable transparent cover

? Available with safe separation according to IEC/EN 61 140, IEC/EN 60 947-1

? Width 22,5 mm

Application

? Level monitoring and control for conductive liquids and powders, e.g. maximum and minimum filling levels, overfilling and protection against dry running

? Monitoring and control of the mixing ratio of conductive liquids

? General resistance monitoring tasks, e.g. limit temperature detection with PTC
