NP93420 IP65 Liquid Gas Pressure Transmitter 316L Pressure Sensor Transmitter
Pressure Sensor Transmitter Working principle
The NP93420 series pressure transmitter in general sense is mainly composed of load cell sensor (also known as pressure sensor), measuring circuit and process connector. The output is stable, the sensitivity is high, the influence of interference and noise is relatively small, the corresponding cost of amplifier circuit is reduced, and the resolution is greatly improved.It can change the physical pressure parameters such as gas and liquid felt by the load cell sensor into the standard electrical signal (such as 4~20mADC, etc.), to supply indicating alarm, recorder, regulator and other secondary instruments for measurement, indication and process adjustment. Special V / I integrated circuit, few peripheral devices, high reliability, simple maintenance, easy, small volume, light weight, easy to install and debug.
Pressure transmitter is a kind of instrument that accepts pressure variable and converts pressure variation into standard output signal in a certain proportion after transferring the sense. 4-20mA DC two-wire signal transmission, strong anti-interference ability, long transmission distance.LED,LCD, pointer three indicator heads, site reading is very convenient. When used in dangerous and explosive fields, diffused silicon pressure transmitter is adopted. The product has the characteristics of low current, low voltage and low power consumption. It belongs to intrinsically safe and explosion-proof product and is equipped with explosion-proof certificate. Can be used to measure viscous,crystalline and corrosive media.The transmitter output signal is transmitted to the central control room for pressure indication, recording or control.
