Combined Pressure and Temperature Sensor working principle

The temperature and pressure integrated transmitter is a commonly used instrument used to measure and transmit two parameters: temperature and pressure. The working principle of the temperature and pressure integrated transmitter is mainly based on physical properties such as resistance, capacitance or semiconductors.

When it comes to measuring temperature, commonly used sensors include thermal resistors and thermistors. They are very sensitive to temperature changes and determine the temperature by measuring changes in resistance.

In terms of measuring pressure, commonly used sensors include piezoresistive sensors and piezoelectric sensors. They determine the amount of pressure by measuring changes in resistance or charge.

These sensors are usually designed with tiny size and weight and can be easily installed on the equipment or systems that need to be monitored. The signals from these two sensors are integrated and passed to the control system through the output signal, thereby achieving the measurement and monitoring of temperature and pressure parameters.
