DIGITAL PRESSURE GAUGE
A digital pressure gauge uses a pressure sensor to convert pressure into an electronic signal, which is then processed by a microprocessor to display a pressure reading.
A pressure sensor, such as a piezoresistive pressure sensor, converts pressure into an electronic signal.The diaphragm deflects when pressure is applied to the sensor.
The deflection of the diaphragm changes the cross-sectional area of the piezoresistive element
Pressure Transmitter
Pressure transmitter measures the pressure of a medium by converting it into an electrical signal. The pressure of the medium is applied to a pressure sensor, which can be a diaphragm, membrane, or other element. The pressure causes the sensor to deform. The pressure causes the sensor to deform. The deformation is converted into an electrical signal. The signal is filtered, amplified, and compensated for temperature. The signal is delivered to another unit for processing.
