Float Operated Level Transmitters

A simple and reliable sensor 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 liquidsand its unique self-cleaning construction which is well suited for sticky or dirty environment with no float hang-ups.

Reed Chain Level Transmitters – FLX

It consists of a float & guide stem assembly in non-magnetic 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 float moves & actuates a series of reed switches in the chain, through a magnet system within it and develops a proportional resistance. The operation is similar to a sliding resistance potentiometer. The sensed resistance is fed to the transmitter located in the enclosure for conversion to a signal of 4-20mA.
