RS485 Level Transmitter
Description of RS485 level transmitter
ULB-I RS485 level transmitter is a fully sealed submersible intelligent level measuring instrument. Based on silicon piezoresistive technology, this level transmitter 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 as well as the non-linearity revision technology. The waterproof cable with vent hose of this RS485 level transmitter is sealed connected with its housing, it is suitable for submersible applications.
Features of RS485 level transmitter
■ Reversed polarity protection and current limiting protection;
■ Against thunder stroke, against radio-frequency interference;
■ Intrinsic safety, or flame-proof safety optional;
■ PVC, PUR or PTFE cable for options.
