Float Level Transmitter


These sensors are used in applications where continuous indication is needed. Float level transmitter's come in " resolution and are constructed out of 316 Stainless Steel, Brass & Buna or Polypropylene. This 3-wire potentiometer requires a signal conditioner or digital panel meter for a 4-20ma output. The Float Level Transmitter is a sensible and economical choice when multi-level switches just will not do. Standard units available up to 8 feet. Units between 8-12 feet available by special order only. Call office for details.

Operating Principle

A series of reed switches and resistors are positioned on a circuit board, which is epoxied inside the stem. A regulated voltage is put across the circuit, which is connected to either the signal conditioner or digital panel meter. The liquid level drives a float containing a magnet past the reed switches closing them in a repeatable pattern limiting the voltage across the circuit as the level rises.  All Float level transmitters are drawn up in AutoCAD per your specifications.
