RS485 Liquid Pressure Transmitter

High Sensibility Pressure Transmitter Sealing And Anti-Corrosion

Working Principle of Pressure Transmitter


NP93420 series uses the piezoresistive effect of semiconductors and micromachining technology to make Wheatstone bridges on the specific crystal direction of single-crystal silicon wafer by using semiconductor processes such as photolithography and diffusion to form a sensitive film. When it is subjected to external force, it will slightly change, and the resistivity will change, so that the bridge arm resistance will change (one pair will become larger and the other pair will become smaller) to excite voltage signal output. Through computer temperature compensation, laser resistance modulation, signal amplification and other processing methods, as well as strict assembly detection, calibration and other processes, the pressure transmitter with standard output signal is produced.

Design feature of Pressure Transmitter


◎The output is stable, the sensitivity is high, the influence of interference and noise is relatively small, the corresponding cost of the amplifier circuit is reduced, and the resolution is greatly improved.

◎special V / I integrated circuit, less peripheral devices, high reliability, simple and easy maintenance, small size, light weight, extremely convenient installation and debugging.

◎aluminum alloy die-casting shell, three end isolation, electrostatic spray protective layer, strong and durable.

◎4-20mA DC two-wire signal transmission, strong anti-interference ability and long transmission distance

◎led, LCD and indicators make it very convenient to read on site. It can be used to measure viscous, crystalline and corrosive media.

◎when used in hazardous and explosive fields, the diffused silicon pressure transmitter is used. The product has the characteristics of low current, low voltage and low power consumption. It is an intrinsically safe explosion-proof product and is equipped with an explosion-proof certificate

◎stainless steel materials and special protective structures, as well as a series of protection measures such as lightning protection, anti-interference, anti-voltage and over-current of the amplification circuit, improve the ability of reliable sealing and anti-corrosion and anti harsh working environment, and fully meet the needs of general industrial field measurement and control
