Description

The WIKA Model RMG sensors with reed chain technology serve as measuring transducers for level measurement in liquid media.

They work on the float principle with magnetic transmission. The float's magnetic system operates a resistance measuring chain within a guide tube, which corresponds to a 3-wire potentiometer circuit. The measurement voltage generated by this is proportional to the fill level. The measurement voltage is finely-stepped as a result of the contact separation of the measuring chain and is thus virtually continuous. Depending on the requirements, contact separations from 5 to 18 mm are available.
