Description

The model FLM-CA magnetostrictive level transmitter is used for the high-accuracy, continuous level detection of liquids and is based on determining the position of a magnetic float according to the magnetostrictive measurement principle.

The FLM-CA emits a 4 … 20 mA output signal, which is configured via buttons within the probe head. Optionally, the FLM-CA is also available with HART ® protocol as a digital output signal. Probe lengths of 100 mm to 3 m and also various temperature and pressure ranges are possible.

In comparison to the FLM-S, the FLM-CA is particularly notable for its very compact and space-saving design. In addition, it can be used in applications with vibrations up to 4 g.
