JC-CW02 silicon piezoresistive micro-pressure core adopts Φ19mm standard outer diameter. The micro-pressure core is the core component of producing the pressure sensor and pressure transmitter. As a small-range and high-performance pressure sensitive component, it can be easily amplified and assembled into a standard signal output transmitter.
JC-CW02 is a packaged diffusion silicon pressure sensitive chip packaged in a 316L stainless steel case. The back of the sensitive chip is pressed and the core back passivation process is applied. Therefore, the product can be used not only to measure clean and non-corrosive gases but also to measure non-corrosive and non-conductive liquid. O-ring side piston pressure seals for easy installation.

1. The least squares method fits the straight line.
2. Compared with the output of 25 °C in the compensation temperature range.
3. Can be used for over-range or down-range, and the amplitude is controlled within ±50%FS.
4. 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.
5. The commonly used compensation method for products is 1.5mA constant current compensation.
6. Do not force to pull the pins or the leads of sensitive components.
7. 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.
8. If you have special requirements on product performance parameters and functions, please contact us.
