Introduction The product uses piezo-resistive OEM pressure sensor as sensing element, which is accurate tested and laser trimmed to compensate zero and sensitivity in wider temperature range. The amplifier circuit transforms sensor signal into standard output signal. Through long-term aging and stability testing, the whole product’s performance is stable and reliable. The product is suitable for rugged environment which needs zero elevation and range adjustment. It is widely used for process control and pressure measure of petroleum, chemi-industry, metallurgy, power station, textile industry, building material, food, medicine, hydrology and environment control, etc. http: //www.microsensor.cn MICRO SENSOR CO.,LTD. - 1 -
