Product Description
Concave film ceramic piezoresistive voltage output sensor module
The CPS18635MV1 and CPS18350MV1 series ceramic pressure sensors are made of refined alumina ceramic base, combined with highly stable sensitive materials, and are refined through processes such as silk screen printing, high-temperature sintering and laser resistance trimming.
The overall dimensions of CPS 18635MV1 are φ18*6.35mm, and the overall dimensions of CPS18350MV1 are φ18*3.50mm. Their unique circuit design significantly improves the reliability of the product. The temperature compensation circuit is integrated inside the sensitive element and has been laser-engraved, so that the internal bridge temperature drift signal is close to zero (≤0.02% FS/℃) within the normal use range (-20℃ to 85℃), which greatly reduces Temperature compensation calibration work required during the production of pressure sensors.
Ceramics have good thermal stability and creep resistance, operate in a temperature range of -40°C to 150°C, and exhibit excellent long-term stability.
The corrosion resistance of ceramics gives it significant advantages in the fields of refrigeration, chemical industry, medicine and environmental protection, and gradually replaces common diffused silicon pressure sensors.
Temperature-compensated ceramic piezoresistive sensor cores have become the first choice for pressure sensing elements in IoT applications due to their extremely high cost-effectiveness, and are widely used in pressure measurement of air, water, oil and other media. They are widely used in automobiles, air compressors, fire hoses, industry and home appliances, etc. Our company can customize pressure sensitive cores of various shapes and sizes according to customer needs.
