Introduction
HBSR-SSR-1/IP is a level switch for detecting liquid in refrigeration systems. Typically, it is installed in/on the receiver, but it is also suited for installation in other locations where a level indication is required. 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.
Technical details
- Reliable design with electronic solid state output and contact function NO or NC
- Designed for the industrial refrigeration industry - max pressure 100 bar
- Clear LED indication at level detection
- Split design which make it possible to mount and make diagnostic without emptying tanks for refrigerant. The electronic part can be dismounted simply by turning two small screws.
