With the development of modern measurement and automation technology, the dosage of the sapphire pressure sensor is growing at 20% a year, the pressure sensor on the market at present, many varieties have different specifications and technical performance, price difference is big, the question is: before the user should choose what kind of sapphire pressure sensor is to meet the practical needs and how to use what to pay attention to:

1, to prevent the sapphire pressure sensor and corrosive medium contact or overheating.

2, prevent the dross in intraductal deposition.

3, measuring the liquid pressure, pressure pipe side should be open in the process, in order to avoid precipitation product residue.

4, measuring gas pressure, the pressure mouth should be open at the top of the process piping, and the upper transmitter should be installed in the process, so that the accumulated liquid injection process pipeline easily.

5, guide pressure pipe shall be installed where the temperature fluctuations small;

6, measuring, steam or other high temperature medium to connect with the buffer tube (coil) such as condenser, should not make the transmitter operating temperature more than limit.

7, measuring, liquid pressure transmitter installation location should avoid the impact of the fluid (water hammer), in order to avoid the sensor damage of overpressure.
