一、Product Overview
Ceramic is recognized as a highly elastic, corrosion-resistant, wear- resistant, shock- and vibration-resistant material.
The CPS1835 series ceramic pressure sensor core produced by optrey tech adopts refined alumina (AL2O3) ceramic base, combined with high-stability sensitive materials, and is refined through silk screen printing, high temperature sintering, laser resistance adjustment and other processes. pressure sensitive element.
The external dimension of CPS1835 series is Φ18mm*3.5mm. Its unique circuit design greatly improves the reliability of the product, and the temperature compensation circuit is integrated in the internal circuit of the sensitive element. (-20℃-85℃), the temperature drift signal of the internal bridge is close to zero (≤±0.02%FS/℃), which can greatly reduce the temperature compensation calibration work required in the production of pressure sensors*.
Ceramics have good thermal stability and creep resistance. Its working temperature range is as high as -40 ~ 150 ℃, and it has good long-term stability.
The corrosion resistance of ceramics makes it unique in the fields of refrigeration, chemical industry, medicine and environmental protection, and gradually replaces conventional pressure sensors such as diffused silicon.
The temperature-compensated ceramic piezoresistive sensor core is the first choice for pressure sensing components in IoT(internet of things) applications due to its high cost performance. It is widely used in pressure measurement of air, water, oil and other media, in automobiles, air compressors, fire It has a wide range of applications in water pipes, industry, home appliances and other fields. Our company can customize pressure sensitive cores of various shapes and sizes according to customer needs.
二、Feature
●Ceramic base with high elastic modulus
●Zero and full scale laser calibration
●Excellent corrosion and wear resistance
●Anti-shock, anti-vibration, wide operating temperature range
●High sensitivity, high precision, high stability
●Internal active temperature compensation, extremely low temperature drift coefficient .
●Small size, easy to package
●Patented circuit and graphic design
*Note: In addition to device drift, the change caused by temperature is also affected by factors such as installation stress relief. It is recommended to perform stress relief and other processes first.
*Note: The temperature coefficient TCR of the sensitive resistor is less than 50ppm, and the drift caused by the change after temperature drift compensation is less than 0.02%FS/℃.
