LFT50 Miniature Float Level Transducer

Brand: Intempco Controls, Inc.

The LFT50 is a miniature float level transducer suitable for level measurement in vessels of up to 36" (914 mm) in height.

Of high quality construction, all wetted parts are stainless 316; other materials are available upon request.

The use of 1" or 1-1/4" NPT fitting accommodates the diameter of the float and allows the units to be installed from the top of the vessel without removal of the float.

For fittings 1/4", 1/2" and 3/4" NPT, the float has to be removed. Upward mounting fittings are also available. Each transducer comes standard with a cable or a 5-pin M12 Micro-DC plug.

The transmitted level signal is generated via a DIN rail transmitter, mounted remotely. Reliable operation and simple design makes the LFT50 an excellent choice for many level sensing applications.
