NH-93420 series liquid level transmitter is a fully stainless steel design, fully sealed submerged solid-state piezoresistive liquid level measuring instrument. This product uses the high stability and reliability famous foreign brands piezoresistive pressure sensor , as well as the high-precision intelligent transmitter processing circuit. It uses the precision digital temperature compensation technology and nonlinear correction technology to convert the liquid level signal of the measured liquid into standard electrical signal output. The waterproof cable is sealed with the shell, and the vent pipe is in the cable, which can be used in the liquid for a long time. The integrated structure and standardized signal output provide convenience for field use and automatic control. The product works in a two-wire system, which is small in size, light in weight, easy to install and easy to use. It is suitable for liquid level measurement and control in the fields of petroleum, chemical industry, power plant, urban water supply and water temperature exploration.
