How does a potentiometric position sensor work?
Potentiometric Position Sensors are resistance-based sensors that use a resistive track with a wiper that is attached to the object whose position is being monitored. Movement of the object causes the wiper to change its position along the resistance track and therefore alter the measured resistance value between the wiper position and the end of the track. In this manner, the measured resistance can be used as an indicator of the object’s position. This is accomplished by using a voltage divider where a fixed voltage is applied across the ends of the resistance track, and the measured voltage from the wiper position to one end of the track yields a value that is proportional to the wiper position. This approach works for both linear displacements and rotary displacements.
What is a magnetorestrictive position sensor?
By their nature, magnetorestrictive position sensors are used to detect linear position. They can be equipped with multiple position magnets to provide positional information on multiple components along the same axis. They are non-contact sensors and since the waveguide is typically housed in a stainless steel or aluminum tube, these sensors can be used in applications where they can be a potential for contamination. In addition, magnetorestrictive position sensors can function even if there is a barrier between the waveguide and the position magnet provided that the barrier is made of a non-magnetic material.
How do capacitive position sensors work?
Capacitive position sensors rely on detecting a change in capacitance value to establish the position of the object being measured. Capacitors consist of two plates separated from each other with a dielectric material between the plates. There are two general methods that are used to detect the position of an object using a capacitive position sensor:
What are the advantages of ultrasonic position sensors?
The advantages of ultrasonic position sensors are that they can work with target objects of different materials and surface characteristics, and can detect small objects over larger distancer than other types of position sensors. They are also resistant to vibration, ambient noise, EMI, and infrared radiation.
What is proximity sensor?
Proximity sensors as well can detect that an object has come within range of the sensor. Both sensors, therefore, might be considered as a specialized form of position sensors. More about these sensors may be found in our related guides about proximity sensors and about motion light sensors.
What is a position sensor?
The position sensor is a device that collects information on the precise position and movement of an object.

It can also detect the thickness of a part, the level of a fluid or the angle of rotation of a shaft. The position sensor is essential for the correct operation of different machines such as machine tools.

Steel Foundries
Steel fabrication and foundry operations require powerful hydraulic cylinders with accurate position sensing. This has become excellent opportunity for our SL Series Linear Position Sensor, as traditional rod-type sensors do not stand up to the extreme high temperatures in this environment.
Oil Refinery Application
Another example of our sensor’s flexibility can be seen in oil refinery equipment, where the SL series position sensor was part of a valve control system used in the coking process. There are particularly high temperatures in this application, making rod-type magnetostrictive sensors unusable.
