INTRODUCTION

HBSR is a level switch for the detection of NH3 and Brine refrigerants.

Typically it is installed in/on the refrigerant vessels, pump separators, economisers or heat exchanger.

The sensor is specially built to resist high pressure and low temperatures.

TECHNICAL DETAILS

Proven sensor technology for simple transsistor output PNP/NPN and NO/NC contact function
Designed for the industrial refrigeration industry - max pressure 100 bar
Clear indication with LED when refrigerant is detected
Split design which makes it easy to install and make diagnostic on. The electronic part can be easily disconnected by 2 screws.
