YW-130 pressure transmitter
The YW-130 piezoresistive pressure transmitter uses a piezoresistive OEM pressure sensor with stainless steel isolation film as the signal measurement element, and has undergone computer automatic testing. The zero point and temperature performance compensation for a wide temperature range have been achieved using laser resistance adjustment technology. The signal processing circuit is located inside a stainless steel housing and converts the sensor signal into a standard output signal. The entire product has undergone strict testing and aging screening of components, semi-finished products, and finished products, with stable and reliable performance. This product is widely used for pressure measurement and control in industrial processes such as petroleum, chemical, metallurgy, power, hydrology, etc. due to its excellent reliability, flexibility, and diversity.
