RS485 Level Sensor
Description
Based on silicon piezoresistive technology, ULB-I RS485 level sensor is designed for liquid level measurement by using silicon die, processing electric circuit of smart level transmitter, and using digital temperature compensation technology with non linearity revision technology. The waterproof cable with vent hose of this RS485 level sensor is sealed connected with its housing.
The output of ULB-I RS485 level sensor is digital signal, which makes the sensor carry on transmission with computer directly.
This intelligent level sensor has already widely used for water & other liquid level measurement and control in petroleum, chemical industry, water conservation etc.
