HBProducts | Liquid Level Sensors | CO2, Butane & Propane| Low Install Height
Technical data: HBLC-CO2
HBLC-CO2 is designed for the measurement of CO2, Butane or Propane refrigerant level in chillers, evaporators and condensers. The sensor detects the refrigerant and transmits the signal to an analog 4-20 mA signal.
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.
