Product details
Brief introduction:
The pressure sensitive element of the pressure sensor used in analytical instruments adopts sputtering technology, and a "micrometer" level resistive film is made by molecular bonding on a 17-4PH stainless steel diaphragm directly acted by the pressure medium. Then, the required Wheatstone bridge is fabricated through microelectronics technology to form a fully metallic sensitive component, without any adhesive or moving parts, and without the need for sealed or oil filled chambers. Therefore, it has the characteristics of being suitable for harsh environments and long-term stable operation. This pressure sensor is a high-performance pressure sensor designed specifically for oilfield logging, well testing, and pressure instruments. The product operates stably for a long time under high temperature conditions, and is resistant to vibration, impact, and moisture. So pressure sensors for analytical instruments are ideal products for harsh environments in oil fields.
