JC628 Sapphire High-temperature Pressure Transducer Overview:
JC628 Sapphire High-temperature Pressure Transducer adopts foreign high-accuracy sapphire pressure sensor and performs temperature and linear compensation through such high- patent technologies as specific signal extraction and peeling etc..The sapphire series is made up of mono- crystalline silicon insulated elements, without any hysteresis, fatigue and creeping. With excellent elastic and insulation characteristics, sapphire is insensitive to temperature change, and can keep good operating characteristic even at high temperature. Sapphire has quite strong radiation immunity characteristics . Furthermore, P – N drifting wont occur to silicon-sapphire semiconductor sensitive elements. Therefore, JC628 products can be extensively used for measuring and controlling high-temperature gas, liquid, fluid, and colloid in airspace and aerospace, petroleum, chemical, metallurgical, electric power, shipping, pharmaceutical, environment protection and scientific research fields, etc.. Therefore, it is ideal for the measurement of high-temperature medium.

JC628 Sapphire High-temperature Pressure Transducer Features:
* Wide measuring range:-100KPa~0~4Kpa…260Mpa

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.
