Working Principle of Pressure Transmitter
NP93420 series utilizes the piezoresistive effect of semiconductors and micro-machining technology to manufacture a Wheatstone bridge on a specific crystal orientation of a single crystal silicon wafer by photolithography, diffusion and other semiconductor processes to form a sensitive diaphragm, when subjected to external force. A slight change occurs, the resistivity changes, and the bridge arm resistance changes (one pair becomes larger and the other becomes smaller) in the excitation voltage signal output, after computer temperature compensation, laser resistance adjustment, signal amplification and other processing methods and strict assembly testing , calibration and other processes to produce pressure transmitters with standard output signals.
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.
◎Dedicated V/I integrated circuit, few peripheral devices, high reliability, simple and easy maintenance, small size, light weight, extremely convenient installation and debugging.
◎Aluminum alloy die-casting shell, three-terminal isolation, electrostatic spraying protective layer, sturdy and durable.
◎4-20mA DC two-wire signal transmission, strong anti-interference ability and long transmission distance.
◎LED, LCD, pointer three kinds of indicators, on-site reading is very convenient. 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
