  • How the pressure transmitter works
    How the pressure transmitter works
    The electrical components that the pressure transmitter feels pressure are generally resistance strain gauges, which are sensitive devices that convert the pressure on the device under test into an electrical signal. The most widely used resistance strain gauges are metal resistance strain gauges and semiconductor strain gauges. The metal resistance strain gauge has two kinds o...

  • Several methods for preliminary judgment of humidity sensor probe performance
    Several methods for preliminary judgment of humidity sensor probe performance
    Correcting humidity is much more difficult than correcting the temperature. Temperature calibration often uses a standard thermometer as a standard, and the calibration standard of humidity is difficult to achieve. Dry and wet bulb thermometers and some common pointer hygrometers cannot be used for calibration, and accuracy cannot be guaranteed because of their requirements. Th...
