CCP serices capacitive ceramic pressure elements circular 21mm chip Pressure sensors
1. Product Description
Pressure sensors are crucial components employed in various industries, and among the three main sensor types, ceramic capacitive pressure sensors stand out. Traditional silicon piezoresistive products face challenges in maintaining measurement accuracy and long-term reliability in high-temperature and corrosive testing environments due to their structural and material characteristics. Ceramic capacitive pressure sensors address these drawbacks, ensuring accurate measurements and long-term reliability in such challenging conditions.
These sensors utilize ceramic as the sensitive element, employing a capacitive structure for non-intermediate liquid dry measurement. The pressure-induced changes in capacitance values serve as the basis for pressure measurement. In contrast to conventional silicon piezoresistive sensors, ceramic capacitive sensors excel in adapting to diverse measuring media environments. They maintain high measurement accuracy over a broad temperature range (-40℃ ~ 125℃). Applications for these sensors span across automotive systems (oil pressure, transmission pressure), petrochemical (air conditioning pressure), pipeline pressure, and industries such as food and medical intake pressure, as well as water pipe pressure.
