A differential pressure transmitter is a device for monitoring pressure changes at two positions
Differential Pressure Transmitter LFT2050
A differential air pressure transmitter is composed of a pressure sensor unit (silicon wafer or ceramic-based), a circuit board to convert pressure into a basic charging signal, and a signal
amplifier. The unit has two pressure chambers separated by a diaphragm. The differential pressure transducer can measure the pressure difference of the two chambers. We call one chamber the
positive-pressure side and the other the negative-pressure side. The circuit board will memorize the shape change of the diaphragm powered by the silicon wafer or ceramic base, which converts the
pressure applied onto the diaphragms into an electrical signal.
Typically differential pressure sensors have two ports to which pipes can be attached and connected to the system in two distinct pressure points from where the differential pressure can be
measured and calculated. Because industrial sensors are used in systems that require high levels of functional safety and robustness, the interfaces they offer can seem a little unusual. Which used
in the right application will provide years of reliability and ease of maintenance.
DIFFERENTIAL PRESSURE SENSOR APPLICATIONS
Differential Pressure Sensor
Differential pressure sensors should only measure fluids with densities that don’t change with temperature variation since this will disturb the precision of your measurement. A good differential
pressure will ensure that the differential pressure is measured accurately independent of other changing parameters and will reliably transmit a signal to represent the differential pressure.
