    HVAC System
    Refrigerant pressure monitoring Pressure transmitters are widely used in refrigerant circuit of air conditioning. During the refrigeration cycle, due to the different states of the refrigerant (vapor and liquid), their pressure values are also different. The pressure transmitter can monitor the pressure change of the refrigerant in real time, and feedback the signal to the control system, the control system according to the feedback signal to adjust the rotation speed of the compressor, adjust the throttle valve opening and other methods to control the flow and pressure of the refrigerant, so as to ensure the air conditioning system works properly.

    Gas Pressure Monitoring
    Industrial gas pressure monitoring In order to ensure safe production of storage and transportation of industrial gas, it's essential to acquired pressure value of industrial gas in real time during storage and gas transmission pipeline. ORR pressure transmitter provides pressure monitoring instruments for industrial gas production and storage, ressure measurement enables the automatic monitoring and regulation of gas production equipment and storage cylinders through the auxiliary system to ensure safe production.

    Pressure Sensor Measurement Theory
    The pressure measurement system is made up of a sensing element with four strain gauges applied to it. The strain gauges are configured in a Wheatstone bridge, where all 4 resistors (labeled R1 thru R4 in Figure 2) are equal, and change by equal magnitude proportionally, when strain is applied. The greater the force or strain (input), the greater the output. A Wheatstone bridge device requires 4 wires for its connection, positive and negative excitation, and positive and negative sensor output.

    Applications of Absolute Pressure Sensors
    With the rise in smart watches and navigation systems, absolute pressure sensors find homes wherever elevation above sea level (altimeter measurement) is required. Weather stations also use them for barometric pressure measurements.
