RS485 Level Sensor
Model: ULB-I
Description
RS485 level sensor is based on silicon piezoresistive technology and 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 level sensor is sealed connected with its housing.
The output of ULB-I level sensor is digital signal, which makes the sensor carry on transmission with computer directly.
Features
◆ Digital communication technology
◆ Data networking gathering
◆ Advanced circuit design and software design
◆ HART protocol or MODBUS protocol(RS485 interface)
