JC627-21 Vacuum Gas Pressure Sensor Overview:
As a new series product specially used for vacuum measurement and control, JC627-21 vacuum gas pressure sensor has completely solved the problem of difficult vacuum measurement. This series product has three specifications, i.e. JC627G negative pressure sensor , JC627A absolute pressure sensor and JC627CA capacitor thin-film absolute pressure sensor , which have widely been used in such fields as pharmaceutical, medical equipment, airspace and aerospace, scientific research, leakage detection and completed automation equipment fields.
By use of a mono-crystalline silicon thick-film sensor, JC627-21 vacuum gas pressure sensor is equipped with a high-accuracy signal processing circuit, with stable and reliable performance, which has solved such disadvantages of domestic diffused silicon-type negative pressure vacuum products as unstable signal and short service life. Normal ranges include 0 ~ 100KPa and 0 ~ 50KPa, etc.

Tips for Type Selection
* The medium to be measured shall be compatible with the material contacting with the product.
* As an additional function code for type selection, the code "E" for intrinsically safe explosion-proof type Ex iaIICT5 denotes that power source must be supplied via safety barrier.
* For other special requirements, please discuss with us and clearly indicate them in the order.
