Overview

The diffusion silicon pressure transmitter uses imported high-precision and high stability pressure sensitive chips. The sensitive chip adopts advanced micro mechanical etching processing technology, which forms a Wheatstone bridge by diffusing four high-precision resistors on the silicon wafer. Due to the piezoresistive effect, the resistance values of the four bridge arm resistors change, causing the bridge to become unbalanced. The sensitive component outputs an electrical signal corresponding to the pressure change. The output electrical signal is amplified and compensated by a nonlinear correction circuit to generate voltage and current signals that correspond linearly to the input pressure

Product Details

1Overview

The pressure transmitter adopts a pressure resistance sensor with a stainless steel isolation diaphragm as the signal measurement element, and has been automatically tested by a computer. The laser resistance adjustment process has been used for zero point and sensitivity temperature compensation over a wide temperature range. The amplification circuit is located inside a stainless steel casing and converts sensor signals into standard output signals. The entire product has undergone rigorous testing and aging of components, semi-finished products, and finished products.

This product is widely used in on-site pressure measurement and control of industrial processes such as petroleum, chemical, metallurgical, power, hydrology, etc. due to its excellent reliability, wide adaptability, flexibility, and diversity.
