Overview:

The ET-BY compact pressure transmitter uses a pressure sensor with a stainless steel isolation diaphragm as the signal measuring element, and is automatically tested by the computer, and the zero point and temperature performance compensation in a wide temperature range is carried out by the laser resistance trimming process. The signal processing circuit is located in the stainless steel housing and converts the sensor signal into a standard output signal. The whole product has undergone strict testing and aging screening of components, semi-finished products and finished products, and its performance is stable and reliable. With its excellent reliability, flexibility and diversity, this product is widely used in pressure measurement and control in petroleum, chemical, metallurgy, electric power, hydrology and other industrial process sites.
