NAME:JC-CM04 Diffusion Silicon Sensor (0kPa~100kPa…100MPa, ∅12.6mm)

JC-CM04 diffused silicon sensor is a pressure measuring component isolated by stainless steel corrugated diaphragm.

Diffused Silicon Pressure Sensor Introduction:

JC-CM04 diffusion silicon pressure sensor is a pressure measuring component isolated by stainless steel corrugated diaphragm. The diffused silicon pressure transducer adopts integrated structure, high pressure resistance value, stable and reliable, especially suitable for medium and high pressure measurement. High-precision and high-stability pressure-sensitive chips, pressure sensitive components are assembled on precision production lines, automatically tested by computer, and provide zero-point correction and temperature compensation for resistors. The diffusion silicon pressure sensor has a small size with wide pressure range, and is suitable for small precision equipment.

1. Electrical connection is a “soft wire” product, the wire length can be customized according to customer requirements.
2. Can be used for down-range, and the amplitude is controlled within ±50%FS.
3. 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.
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 the product is 1.5mA constant current compensation. It is recommended to give priority.
6. Do not force or pull the pins of sensitive components.
