Industrial Pressure Transmitter - How It Works
The electrical component of the industrial pressure transmitter to feel the pressure is generally a resistance strain gauge, which is a sensitive device that converts the pressure on the measured component into an electrical signal. The most widely used resistance strain gauges are metal resistance strain gauges and semiconductor strain gauges. There are two types of metal resistance strain gauges: filamentary strain gauges and metal foil strain gauges. Usually, the strain gauge is tightly bonded to the matrix that generates mechanical strain through a special adhesive. When the stress of the matrix changes, the resistance strain gauge is also deformed together, so that the resistance value of the strain gauge changes, so that the strain gauge changes. The voltage across the resistor changes.
