Applications

AT8-DA4 transducer is known to be used in multiple industrial processes due to its excellent features. Some of the most common applications include:

• Hydraulics – The AT8-DA4 transducer is used for pressure measurements in hydraulic systems because of its high resolution and accuracy. It is integrated into these systems to allow the measuring of pressure variation from positive to negative areas, thus ensuring more efficient operations.

• Automotive – It is used in motors and engines of cars to measure the pressure in the lubrication systems efficiently. It further helps in controlling the speed of the engine thus enhancing the performance.

• Manufacturing – It finds its application in various manufacturing processes to monitor the pressure of various fluids with great accuracy. This further improves efficiency of production and reduces the production costs significantly.

Working Principle

AT8-DA4 transducer converts an input pressure signal into an electrical signal using a pressure sensing element. The sensing element in this transducer consists of a diaphragm which deflects according to the changes in pressure. The diaphragm is connected to a strain gauge which changes its electrical resistance with any deflection in the diaphragm. The signal is then further amplified and then provided to the user at the output through the signal conditioner.

This transducer is equipped with a temperature compensator which helps maintain accuracy in operation over a broad range of temperatures. Generally a silicon-diaphragm is used in this transducer which is a heat resistant material, thus its response is independent of the temperature variation.

In a typical operation, the transducer converts the electrical signal to a current or a voltage signal and then transmits it to the customer. It can be used for various pressure measurements; it is accurate up to range of ±0.25% FS. Furthermore, it operates on a wide range of temperatures and is also resistant to shock and vibration.

Conclusion

The AT8-DA4 transducer is an advanced industry tool which serves as an important accessory in various industrial operations. Its working principle is based on measuring pressure variation using a pressure sensing element which transmits the signals to the user. Its wide range of applications in hydraulic, automotive and manufacturing sectors speaks for its efficiency and accuracy. As such, AT8-DA4 is the transducer of choice in various industrial environments.
