Position sensors play a vital role in many industries by accurately measuring the position of an object or actuator. A wide variety of sensors are available for different applications, including angle and linear position sensing. One such example is VA38847K, a device manufactured by Proximity Research, Inc. This article will discuss the application field and working principle of VA38847K.

VA38847K Application Field

VA38847K position sensor is a device suitable for applications in industrial and automotive sectors. It is designed for reliable angle measurement and linear position measurements. This device is particularly suitable for actuator systems and assembly lines requiring precision angle and linear position measurements. The accuracy of this device\'s measurements ranges from 0.1° to 0.5°, depending on the application. This makes the VA38847K an ideal choice for assembly lines and other applications requiring highly accurate measurements.

VA38847K Working Principle

The VA38847K position sensor comes equipped with an angle measurement IC. The IC utilizes two optical measurement principles to obtain angle measurements - sine and cosine. The sine measuring principle uses two waveforms of equal amplitude and period, while the cosine measuring principle requires two waveforms of different amplitudes. The IC part of the device then ”reads” the angles between the waveforms to obtain accurate readings. Alternatively, the device can also be used to measure linear positions. In this case, the IC reads the linear distance between two points using optical technology.

The VA38847K also features an integrated temperature sensor which allows the device to compensate for temperature changes. This ensures that the readings are as accurate as possible. Additionally, the device also features over-voltage, over-current and dielectric breakdown protection which helps protect the device from the harsh industrial environments.

Conclusion

VA38847K is an advanced position sensor designed for accurate angle and linear position measurements. It is suitable for industrial and automotive applications, as it comes with features such as temperature compensation and protection against harsh industrial environments. This position sensor is highly accurate, with readings ranging from 0.1° to 0.5°, depending on the application. These features make VA38847K an ideal choice for actuator systems and assembly lines requiring precision measurements.
