Sigma Instruments & Controls - Level Transmitters

We are one of the foremost manufacturers and suppliers of a comprehensive assortment of Level Transmitter. Our range is appreciated for higher degree of accuracy, precision & compact design, durability and longer service life.

This is more reliable techniques for continuous level indication and controlling of any liquid, since it is add on magnetic level indicator, has no direct contact with actual liquid. Hence there is no question of corrosion, Sp. Gravity, temp, pressure, for smooth operation, this sensor tube is magnetically actuated with movement of magnetic float / tip.
Construction & Working:The sensor tube is manufactured from non magnetic material to achieve undisturbed flux. it contains chain of reed switches & resisters. A magnetic float are tip tracks the level & activates reed chain. The change in resistance is in proportional to level & same is converted into 4-20 ma current by loop power transmitter and LCD unit indicates the reading.
