Product Details

MODBUS Level Sensor


ULB-I MODBUS level sensor is a fully sealed submersible intelligent level measuring instrument. Based on silicon piezoresistive technology, this product is designed for liquid level measurement by using silicon die with good stability and processing electric circuit of high accuracy smart transmitter, and using precise digital temperature compensation technology and the 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 MODBUS level sensor is digital signal, this makes this transmitter carry on transmission with computer directly.
