Exquisite Soild Structure NH-93420 Series Liquid Level Transmitter For Various Liquid level Measurement Applications
High Stability And Precision NH-93420 Series Liquid Level Transmitter Fully Protected Operating Principle
NH-93420 series liquid level transmitter is designed as fully stainless steel and fully sealed submerged solid piezoresistive liquid level measuring instrument. This product is composed of the high stability and reliability piezoresistive pressure sensor of foreign famous brands, as well as the high-precision intelligent transmitter processing circuit. It also adopts precision digital temperature compensation technology and nonlinear correction technology to convert the measured liquid level value into standard signal output. Water proof cable is connected with and outer shell, the vent pipe in the cable, so it can keep working for a long time. The integrated structure and standardized signal output provide convenience for field use and automatic control. This product works in a two-wire system. It 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 plants, urban water supply, and water temperature exploration.
Pa: pressure of the sensor's frontal liquid level
p: Density of measured liquid
Po: atmospheric pressure above liquid level
g: Local gravity acceleration of the site
h: Depth of the sensor into the liquid |
NH-93420 Series Liquid Level Transmitter Design Feature
◎ High stability and precision.
◎ Exquisite structure, which can be directly put into the measured medium to measure the liquid level, and the installation and use are quite convenient.
◎ Solid structure, no movable parts, high reliability and long service life, high-precision measurement can be carried out from water, oil to paste with high viscosity, and is not affected by the foaming, deposition and electrical characteristics of the measured medium.
◎ Wide range temperature compensation.
◎ It has power supply reversing phase protection, overload current limiting protection, lightning protection and radio frequency interference protection.
