NP93420 series diffused silicon pressure sensors are all imported chips, after careful structural design, signal processing and assembly, and in strict accordance with the national standards for testing and produced a new generation of pressure sensors. The series of products have stable output, high sensitivity and precision, and good temperature characteristics, and strong anti-interference ability.
NP93420 series is the use of semiconductor piezoresistive effect and micro mechanical processing technology, in specific crystal monocrystalline silicon slice up, made of lithography, diffusion, and so on semiconductor technology - wheatstone bridge, form the sensitive diaphragm, when external force is produced, the resistivity changes, make the bridge arm resistance change (a bigger pair of smaller) in the excitation voltage signal output, Through computer temperature compensation, laser resistance adjustment, signal amplification and other processing methods and strict assembly detection, calibration and other processes, the pressure transmitter with standard output signal is produced.
•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 maintenance, easy, small size, light weight, installation and debugging is very convenient.
•Aluminum alloy die - cast shell, three - end isolation, electrostatic spray protective layer, durable.
•4-20mA DC two-wire signal transmission, strong anti-interference ability, long transmission distance.
•LED, LCD, pointer three indicator head, field reading is very convenient. It can be used to measure viscous, crystalline and corrosive media.
•Diffused silicon pressure transmitter is used in dangerous and explosive fields. The product has the characteristics of low current, low voltage and low power consumption. It is an intrinsically safe and explosion-proof product, and is equipped with explosion-proof certificate.
•The use of stainless steel material and special protection structure, and the amplifier circuit lightning, anti-interference, anti-voltage, over-current and a series of protection means, improve the reliable sealing anti-corrosion and anti-harsh working environment ability, completely suitable for the general industrial field measurement and control needs.
