What is a ultra high temperature pressure sensor ? 

High temperature resistant pressure sensor is a kind of pressure sensor using high temperature resistant core or sapphire core as pressure measuring material, which is widely used in industry . It is a common method to collect pressure signal in the pressure measuring position of high-temperature steam and high-temperature fluid. Another situation to use ultra high temperature pressure sensor is  the use of pressure measurements in oil fields ,that you may not be familiar with . The temperature resistance of PPM-S314C ultra-high temperature pressure sensor is up to 175 ° C . When the ambient temperature is higher than 175 degrees need to be customized .

Process of PPM-S314C ultra high temperature pressure sensor

PPM-S314C is an ultra-high temperature pressure sensor with excellent long-term stability. In order to ensure the good working performance in the harsh environment of the oilfield, Changsha Taihe Electronic Equipment Co. , Ltd. adopts high-performance heat-resistant sensitive chip and sputtering thin film technology to produce . The etching process is directly formed on the stainless steel elastic diaphragm . It is realizes the inorganic transformation of the sensitive element, overcomes the unstable factors such as creep, hysteresis and aging brought by organic adhesive, and greatly improves the long-term stability of the product.

Features

1. High temperature resistance ;
2. Small size ;
3. High precision ;
4. Good long-term stability ;
5. Fatigue and impact resistance

 Application of PPM-S314C ultra high temperature pressure sensor

Ultra-high temperature pressure sensors are mainly used in oil drilling, logging, well testing，and other downhole instruments such as downhole pressure gauge and MWD .

Most of the pressure sensors used in oil and gas must have strong anti-interference ability, strong and durable, anti-fatigue and continuous impact ability, high temperature resistance, explosion-proof and etc . It is not easy to keep the safety and stability of the sensor in high temperature environment. 

The most commonly situation of using The S314C ultra-high temperature pressure sensor is in the downhole pressure gauge and MWD . High temperature, high vibration and strong interference bring great challenge to precise pressure measurement in drilling operation. PPM-S314C ultra-high temperature pressure sensor is made by high-temperature core, stainless steel reinforcement and sputtering film process , So that it can work steadily and continuously under harsh conditions. With the further development of drilling technology, the application of downhole pressure gauge also increases the functions of storage and wireless transmission, which greatly improves the benefit of oilfield production .
