Ceramic Capacitive Pressure Element/Sensor

Content

Overview

Ceramic Capacitive Pressure Sensor uses ceramic as sensitive element to form capacitor structure and execute measurement without intermediary liquid. Compared with silicon resistance and ceramic resistance, it can be applied to all kinds of medium environment and maintain high accuracy in a wide temperature range(-40℃~150℃).

Background

With rapid development of intellectualization, the demand for sensors is increasingin all industries. As one of the three main types of sensors, pressure sensor is widelyused. Due to structure and material properties of silicon or ceramic resistance, it is difficult to ensure measurement accuracy and long-term reliability at high temperature and corrosiveenvironment. However, ceramic capacitive pressure sensor can overcome the shortages and outperforms silicon orceramic resistance at extreme environment.
