Combined pressure and temperature sensor for Simultaneous measurement of pressure and temperature.

SI-706 Combined Pressure and Temperature Sensor-Dual function

The Combined pressure-temperature sensor uses a special core. Thermocouple types are: J, K, E type or PT100 platinum resistance. Integrated structure of temperature and pressure. Measure the medium pressure and temperature at the same point at the same time. The combined pressure and temperature sensor has a built-in temperature / pressure sensor. The two outputs do not affect each other. Consuming the power of one sensor can complete the pressure and temperature measurement. Widely used in scientific research, military industry, petrochemical, electric power, metallurgical machinery and environmental protection fields. Such as oil well temperature and pressure measurement, diesel engine common rail temperature and pressure measurement, injection machinery temperature and pressure measurement.

Why use a Dual Pressure and Temperature Sensor?

Temperature and pressure integrated dual-function type: pressure, temperature measurement. The main reason for using dual pressure and temperature sensors is to save space. It can be widely used in the occasions where pressure and temperature need to be measured simultaneously in industrial control detection.

The integrated temperature coefficient organically integrates the temperature sensing element (thermal resistance or thermocouple) with the signal conversion and amplification unit. Thermocouple types are: J, K, E type or PT100 platinum resistance. Integrated structure of temperature and pressure. Simultaneously measure the medium pressure and temperature at the same point. It is suitable for measuring the temperature of the medium while measuring the pressure.

Working principle of Pressure and Temperature sensor

Thermocouples or thermal resistance sensors convert the measured temperature into electrical signals. Then send the signal to the input network of the transmitter. The network contains related circuits such as zero adjustment and thermocouple compensation.

The signal after zero adjustment is input to the operational amplifier for signal amplification. The amplified signal is output with 4-20ma DC current after being calculated and processed by the v / i converter. The other channel is processed by the a / d converter and displayed on the meter header.

There are two types of transmitter linearization circuits, both of which use feedback. For the RTD sensor, use positive feedback to correct it. For the thermocouple sensor, the multi-section broken line approach method is used for correction.
