Introduction
HBLT capacitive liquid level transmitters are used to measure liquid levels in refrigerant vessels. The HBLT transmits an active 4-20 mA signal which is proportional to the liquid level.
4 mA when the transmitter does not register liquid and 20 mA when the entire transmitter is surrounded by liquid .The 4-20 mA signal from HBLT can be used in conjunction with a controller e.g HBLT-C1 to control the liquid level.
Technical details
- Proven and reliable design with process signal output of 4-20 mA.
- Split design makes it easy install and make diagnostic. The electronic parts can be easily disconnected with 2 small screws.
- Simple calibration function and the possibility to reduce the effect of liquid peaks.
- Designed for the industrial refrigeration industry - max pressure up to 100 bar & high protection degree.
