Introduction
JC-CE01 sapphire is composed of single crystal insulator elements without hysteresis, fatigue and creep; sapphire has very good elasticity and insulation properties (within 1000 ° C), is not sensitive to temperature changes, Even under high temperature conditions, it has good working characteristics; sapphire has strong radiation resistance; and silicon-sapphire semiconductor sensitive components, without p-n drift, can be used in a variety of complex environments.
The sensor consists of a double diaphragm: a pressure sensitive membrane and a measuring membrane. A heteroepitaxial silicon strain-sensitive circuit diaphragm on sapphire is welded to the titanium alloy measuring diaphragm. The measured pressure is transmitted to the measuring diaphragm. Under the action of pressure, the titanium alloy measuring diaphragm generates micro-deformation, which causes the bridge output to change, and the magnitude of the change is proportional to the measured pressure. This series of cores has excellent temperature characteristics and overload resistance.

Note:
1. The least squares method fits the straight line;
2. Can be used for down range, and the amplitude is controlled within ±50%FS.
3. The maximum pressure of the system should be less than the overload protection limit of the sensor, otherwise it will affect the service life of the product and damage the product.
4. Do not force to pull the pins or the leads of sensitive components.
5. Protect the isolation diaphragm at the front end of the pressure sensitive component to prevent the impact of the pressure sensitive component from damaging the sensitive component.
