Magnetic Float Operated Level Transmitter

Magnetic Float Operated Level Transmitter


Sigma's Magnetic Float Operated Level Transmitter is a simple and reliable technique for continuous level indication and control of any liquid, chemically compatible with the (sensor) material, unaffected by electrical conductivity, temperature, pressure or viscosity. The float is designed for variety of liquids.The Transmitter consists of a float & guide stem assembly in nonmagnetic material to achieve undisturbed flux. A chain of closely spaced glass encapsulated reed switches & resistors are placed inside the guide tube. During rise and fall of liquid level, the magnetic float moves & actuates a reed switch in the chain. The sensed voltage is fed to the transmitter located in the enclosure for conversion to a signal of 4-20 mA.
