ULB-I RS485 digital level Sensor
Descriptions:
ULB-I RS485 digital level Sensor is 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 transmitter is sealed connected with its housing, it is suitable for submersible appl ications.
The output of ULB-I is digital signal, this makes this transmitter carry on transmission with computer directly.ULB-I intelligent has already widely used for water & other liquid level measurement and control in scientific research domain, and petroleum, chemical industry, medicine, water conservation etc.
