TD228-3002P Application Field and Working Principle

The TD228-3002P Pressure Transmitter is a type of transducer used for measuring static and dynamic pressure and providing a signal output of transducer, usually with a conventional current signal 4-20mA. It is accurate up to 0.5%, while providing excellent media compatibility with both corrosive and non-corrosive fluids. The product offers a wide variety of mounting options including integral, remote, enclosed, or panel mounting.

Application Fields

TD228-3002P Pressure Transmitter is widely used for measuring pressure of corrosive fluids in industries such as marine, petroleum, chemical, and power. It can also be used for applications of industrial, pressure, and process control. Other application includes monitoring of liquid producing, customer pressure, steam pressure, filter pressure, water pressure, blood pressure, and reflux pressure. The Pressure Transmitter is also suitable for monitoring gas pressure in domestic heating systems.

Working Principle

The TD228-3002P Pressure Transmitter works in accordance with the principle of piezoelectricity. Piezoelectric transducers work by using the piezoelectric effect to convert mechanical and acoustic signals into electrical signals. In this way, a pressure signal can be converted into an electrical signal. The TD228-3002P Pressure Transmitter comprises of a diaphragm, which is an actuator that uses the piezoelectric principle to convert a pressure signal into an electrical signal. The diaphragm is made from a special material that is able to generate electric charge when it is compressed or relaxed. When a pressure is applied to the diaphragm, a voltage signal is generated.

The voltage signal produced by the diaphragm is then amplified and converted into a current signal with a linear output voltage range from 4-20mA. The current signal is then fed to the measuring device, such as an indicator display for an operator to observe.

Conclusion

The TD228-3002P Pressure Transmitter is a widely used transducer for measuring static and dynamic pressure. The product offers a wide variety of mounting options and is suitable for monitoring gas pressure in domestic heating systems as well as pressurization in other industries such as marine, petroleum, chemical, and power. The Pressure Transmitter is based on the principle of piezoelectricity, whereby a pressure signal is converted into an electrical signal through the use of a diaphragm. It then converts the signal to an amplified current signal of 4-20mA that is fed to the measuring device.
