Typically, it is installed in/on the receiver, but it is also suited for installation in other locations where a level indication is needed. The sensor's measurement principle makes it unique for these purposes, since the properties of the measurement principle as well as its special construction allows it to withstand high pressure and low refrigerant temperatures.

Product features:

Complete solution with sensor and transmitter in one unit.
Simple to install by one thread sleeve. A cost optimised solution.
LED indication of power supply and alarm status.
Unique split design which make it easy to install and make diagnostic. The electronic part can be easily dismounted from the mechanical part by 2 small screws.
