Product Description
Temperature Compensated Flat Film Ceramic Piezoresistive Sensor Core
The RS186A temperature-compensated flat-film ceramic pressure sensor core is made of a refined alumina ceramic seat, combined with highly stable sensitive materials, and refined through processes such as silk screen printing, high-temperature sintering and laser resistance trimming.
The overall dimensions of CPS 18635G are φ18mm*6.35mm, and its 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.
The temperature-compensated ceramic piezoresistive sensor core has become the first choice for pressure sensing components in Internet of Things applications due to its extremely high cost performance. It is widely used in pressure measurement of air, water, oil and other media. It is 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.
