Position sensors (or transducers) convert physical dimensions into a measurable signal. When it comes to angle measurement, linear position measuring, and other motion detection, 8156V1T3L.5FS (from here onward referred to as 8156) is a powerful transducer with a unique set of features. Understanding the capabilities and principles of operation of this component is key to successful designs for motion sensing.

Application Field of 8156

8156 is a differential transformer used for measuring linear and rotary acceleration. A differential transformer is an electric device comprising of two coils wound on a core which are used to measure the self-inductance of a coil. It is an active device with built-in conditioning electronics, which will output a voltage signal proportional to the acceleration passing through it. 8156 applications include:

• Machine condition monitoring
• Remote sensor applications
• Vibration monitoring
• Rotational speed monitoring
• Nuclear power plant monitoring
• Robotics
• Industrial automation

Working Principle of 8156

8156 consists of a Hall effect sensor, signal conditioning electronics and a differential transformer, all integrated into a single package. The device works by sensing the magnetic field around the primary coil. An amplifier can sense the changes in the strength of the magnetic field and convert them into a voltage signal, which is then conditioned by the signal conditioning electronics and output from the device.

The primary coil of the differential transformer is energized with a current of typically 100mA to 1000mA. This current generates a magnetic field around the coil, which causes flux leakage into the secondary coil. The secondary coil then induces a voltage signal proportional to the current in the primary coil. This voltage signal is then conditioned and output from the device in the form of a linear voltage signal.

The differential transformer is capable of accurate linear position measurement up to an accuracy of 0.1%. It also has the ability to measure rotary acceleration to a high degree of accuracy. In addition, it also offers temperature compensation, ensuring that the measured signal is not affected by temperature changes.

Conclusion

8156 is a powerful transducer with unique features that makes it suitable for applications such as machine condition monitoring, remote sensing, robotics, and industrial automation. It has a differential transformer for linear position measurements and rotary acceleration with accuracy up to 0.1%. The built-in signal conditioning electronics ensures that the output of the device is temperature compensated and accurate. 8156 is a great tool for monitoring various mechanical and electrical parameters in a wide range of motion sensing applications.
