SWI TR420 Series | Continuous Output Float Level Transmitter

Description

The vertically-mounted TR420 Continuous Output Level Transmitter is equipped with an integral signal conditioner and provides a reliable 4-20 mA, 0-5 VDC or 1-5 VDC proportional electronic output in tank levels up to 12 feet. It can be used to input programmable controllers, meters and other digital receivers for accurate and continuous measurement in many liquid level applications. Float materials are available in stainless steel, polypropylene or buna with a selection of mounting types. The variety of float styles and densities afford the best and most direct means for continually monitoring surface interfaces of dissimilar liquids within a single tank. Additional options include high level and low level alarms as well as mounting materials in brass or 316 stainless steel.

Principles of Operation

As the float travels with the fluid level within the tank, the float's internal magnets actuate a series of reed switches and resistors along the stem. The signal is electronically conditioned through the built-in transmitter board to provide a proportional current output.
