Ceramic piezoresistive pressure sensor

Industrial process control:

Solution: SelectionCeramic piezoresistive pressure sensor(Corrosion resistant)+Pt100 thermistor (high precision), outputting 4-20mA standard signal, connected to PLC or DCS system.

Key points: Emphasize long-term stability, resistance to electromagnetic interference, and explosion-proof certification (such as Ex ia).

Automotive Engine Management System:

Solution: Select MEMS piezoresistive intake manifold pressure/temperature integrated sensor, output 0-5V analog signal or PWM signal.

Key points: High reliability, wide operating temperature range (-40 ℃~125 ℃ or above), and fast response are required.

Smart Home/IoT:

Solution: Use an integrated digital temperature and pressure combination sensor (such as BMP280) to communicate with the MCU through an I2C interface.

Key points: Pursuing small size, low power consumption, low cost, and easy mass production.

Response time: During dynamic measurement, attention should be paid to the frequency response characteristics of the sensor.

Long term stability: refers to the ability to maintain performance parameters unchanged within a specified period of time.
