Pressure and DP Transmitter with Flange Diaphragm
Description:
A pressure and differential pressure (DP) transmitter with a flange diaphragm is a type of pressure measurement device that combines the functionality of measuring both absolute pressure and differential pressure, utilizing a diaphragm with flange connections for installation.
The transmitter consists of a diaphragm sealed within a housing, which is connected to the process or system where pressure is being measured. The diaphragm separates the process fluid from the sensing element inside the transmitter. Flange connections on the diaphragm enable easy installation and connection to the process piping.
In the case of absolute pressure measurement, the diaphragm is exposed directly to the process pressure, providing an accurate reading of the pressure in the system relative to a reference pressure. For differential pressure measurement, the diaphragm senses the difference in pressure between two points in the system, allowing for flow rate calculations or level measurements.
The transmitter contains electronic components, including strain gauges or capacitive sensors, which convert the diaphragm deflection into an electrical signal. This signal is then processed and amplified to provide an output corresponding to the measured pressure or differential pressure.
