What is a Differential Pressure Transducer?

A differential pressure transducer is a device that measures the difference in pressure between two points and converts this measurement into an electrical signal. This signal is then used to monitor and control processes in various industries. The Yokogawa EJA118E is known for its high accuracy and reliability in differential pressure measurement.https://www.zyyinstrument.com/differential-pressure-transmitter/yokogawa-eja118e

How Does a Differential Pressure Transducer Work?

A differential pressure transducer works by using a sensing element, typically a diaphragm, that responds to pressure differences between two points. The diaphragm's deflection is proportional to the pressure difference, and this deflection is converted into an electrical signal. The Yokogawa EJA118E uses advanced sensing technology to provide accurate and stable measurements, making it suitable for critical applications.
