0 ~ 200MPa Downhole Instruments High Temperature Pressure Transmitter
0 ~ 200MPa PPM-T322C Downhole Instruments High Temperature Pressure Transmitter
Product Introduction:
The sensitive chip of PPM-T322C high temperature pressure transmitter is made by ion sputtering thin film technology. It is directly formed on the stainless steel elastic diaphragm by sputtering and etching process, which completely realizes the inorganicization of the sensitive components and overcomes the organic adhesion. The unstable factors such as creep, hysteresis, and aging caused by the adhesive tape greatly improve the long-term stability of the product.
Applications :
Oil drilling, logging, well testing, downhole instruments, digital pressure gauges,
water injection, submersible pumps, multi-parameter inclinometers,
bomb-borne engines, aircraft hydraulics, etc.
