JC628 High-temperature Pressure Transmitter Overview:
JC628 high-temperature pressure transmitter
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 won't occur to silicon-sapphire semiconductor sensitive elements. Therefore, JC628 high-temperature pressure transmitter
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.
