HPT621 Series Smart Capacitance Level Sensors

. Profiles:

 

HPT621 smart capacitance liquid-level sensor is the customized sensor meter for precise measuring of the liquid level of automobile oil tanks, sealed tankers, trucks fuel tank, locomotives tanks and oil depots, etc.

The whole sensor is free of any mobile or elastic part and is featured with the good impact resistance, convenient installation, high reliability, high precision, and stable performance. HPT621 support local renew calibrate zero and span by two calibration wires, It can not only be installed on various occasions requiring precise level measuring of gasoline, diesel, water and hydraulic oil, etc, but also be Application for measuring of various non-conductive liquids..

In addition, it can be customized to use for conductive medium measuring on occasions with quite poor conditions, quite serious electromagnetic interference, or dramatic stirring. Sensor support client’s local calibration zero and span, so that sensor can use very easy for different mediums and with a very high precision reading data
