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 liquidThe 4-20 mA signal from HBLT can be used in conjunction with a controller e.g HBLT-C1 to control the liquid level.Product Features:Proven and reliable design with process signal output of 4-20 mA.Split design makes it easy install and make diagnostic.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.
