Path transducer, linear potentiometric
Linear potentiometric displacement transducers consist of an elongated resistive element and a slider. The slider moves along the resistive element and thereby picks up a partial resistance that is dependent on position. In many cases, the resistance element consists of conductive plastic. Linear membrane potentiometers are a variant of the linear potentiometric displacement transducers. Linear potentiometric displacement transducers are absolute measuring sensors. The current position information is available immediately after the supply voltage is applied.... Read more

The measurement resolution of wire potentiometers depends on the thickness of the wire. With conductive plastic potentiometers, the resolution is virtually infinite. Conductive plastic potentiometers enable high traverse speeds.
The input voltage applied to the potentiometer has an important influence on the measuring accuracy. This goes directly into the accuracy. The supply voltage should therefore be as constant as possible. Linear potentiometric displacement transducers are absolute measuring sensors. Immediately after the supply voltage is applied, the current path information is available.
Traversing speed
For the contacting measuring method, the possible traversing speed of the sensor must be observed. The possible traversing speed is essentially dependent on the contact pressure of the slider on the resistance element. The travel speed, also called adjustment speed, is maximum approx. at 0.5...1 m/s.
Linearity
The linearity, also called non-linearity, is an important criterion for the evaluation of the sensor. The nonlinearity is the maximum deviation of the actual characteristic curve from the reference line.
Three methods can be used to determine the reference line: best fit straight line (BFSL), boundary point setting, and initial point setting. Each of these methods leads to different results. For the comparability of nonlinearity data of different products, the respective method used must be known, since the value of the linearity data clearly depends on the method used to determine the nonlinearity.
When setting the boundary , the reference line passes through the start of the characteristic curve and the end of the characteristic curve. This method specifies the largest possible deviation between the characteristic curve of the sensor and the reference line determined according to this method. The difference in the determined nonlinearity can be up to a factor of 2 larger with this method than with the smallest value method.
The smallest value method places the reference line so that the maximum positive and negative deviations are equal. This method is often more informative than the limit point method. The smalles value method gives the smallest error values.
The initial method is used less frequently. The measurement resolution of wire potentiometers depends on the thickness of the wire. With conductive plastic potentiometers, the resolution is virtually infinite. Conductive plastic potentiometers enable high traverse speeds.

What is a linear potentiometric displacement transducer?
A linear potentiometric displacement transducer is a measuring device that is used to measure the linear movement or displacement of an object. It consists of a potentiometer that has a variable resistance change when the displacement transducer moves. The resistance changes proportionally to the position of the transducer and can be used as an output signal to measure the deflection. This measuring principle is often used in industrial applications such as automation technology or robotics.
How does a linear potentiometric displacement transducer work?
A linear potentiometric displacement transducer, also known as a linear potentiometer or sliding resistor, consists of a fixed resistance element, a wiper and a moving contact.
The resistive element is usually a spiral-shaped metal strip that is applied to an insulating carrier material. The wiper is a moving contact that slides along the metal track. The moving contact is often attached to a moving component whose position is to be measured.
The wiper is electrically connected to both ends of the metal track, creating a variable resistance. As the slider moves along the metal track, the resistance value between the slider and the two ends of the resistance element changes.
To measure the resistance value, a voltage is applied to both ends of the resistance element. The output voltage is then tapped at the wiper. Depending on the position of the wiper, the resistance value changes and therefore also the output voltage.
The output voltage can then be converted into an electrical signal and used to control other devices or systems. As the change in resistance is linear with the position of the wiper, the potentiometric displacement transducer can be used to measure linear movements.
However, it is important to note that linear potentiometric displacement transducers are susceptible to wear and tear and therefore require regular maintenance or replacement to ensure accurate measurements.

What accuracy can be achieved with a linear potentiometric displacement transducer?
The accuracy that can be achieved with a linear potentiometric displacement transducer depends on various factors, such as the quality of the sensor, the measuring environment and the evaluation electronics. In general, it can be said that linear potentiometric displacement transducers can have an accuracy of around ±1% of the measuring range. However, it is important to note that this accuracy can vary depending on the application and that there are also high-precision potentiometric displacement transducers that can achieve an accuracy of ±0.1% or even higher.
How is a linear potentiometric displacement transducer calibrated and adjusted?
The calibration and adjustment of a linear potentiometric displacement transducer usually takes place in several steps:
1. Mechanical adjustment: First of all, the displacement transducer must be mechanically installed and aligned correctly. This includes the correct mounting of the housing and the alignment of the measuring flask or the measuring axis.
2. Zero point calibration: To set the zero point of the displacement transducer, the measuring piston or the measuring axis is moved to the starting position in which the value zero is displayed. This can be done by moving it manually or by using a zero point calibration tool.
3. Endpoint calibration: To set the end points of the displacement transducer, the measuring piston or the measuring axis is moved to the maximum and minimum position. The corresponding measured value is read and compared with the actual physical end points. If deviations occur, the end points of the displacement transducer can be adjusted to ensure accurate measurement.
4. Linearity calibration: To ensure the linearity of the displacement transducer, the measuring piston or the measuring axis is placed in several intermediate positions and the corresponding measured values are recorded. The recorded measured values are then compared with the ideal linear function in order to detect deviations. If necessary, correction factors or curves can be applied to improve linearity.
The exact steps and procedures may vary depending on the manufacturer and model of the displacement transducer. It is important to follow the manufacturer's instructions and, if necessary, consult a specialist to carry out correct calibration and adjustment.

What challenges can arise when using a linear potentiometric displacement transducer and how can they be solved?
Various challenges can arise when using a linear potentiometric displacement transducer:
1. Wear and tear: The mechanical movement of the wiper on the potentiometer resistor element can cause wear. This can impair the accuracy and reliability of the displacement transducer. To solve this problem, regular maintenance and cleaning measures should be carried out. It may also be necessary to replace the travel sensor.
2. Mechanical faults: External mechanical influences such as vibrations or shocks can also affect the accuracy of the displacement transducer. To minimize this problem, the displacement transducer should be mounted in a stable and vibration-free environment. If necessary, shock absorbers or other mechanical protective measures can also be used.
3. Electrical faults: Electromagnetic disturbances or interference can impair the measuring accuracy of the displacement transducer. To solve this problem, suitable protective measures should be taken, such as using shielded cables or placing the displacement transducer away from strong electromagnetic fields.
4. Nonlinearity: Another problem can be the non-linearity of the displacement transducer, i.e. the output voltage or current of the displacement transducer does not change proportionally to the actual change in position. To solve this problem, it may be necessary to calibrate the displacement transducer. Here, the output voltage or current is measured as a function of the actual position of the displacement transducer and a correction function is created to compensate for the non-linearity.
5. Temperature dependence: The output variables of a displacement transducer can also be influenced by temperature fluctuations. Temperature compensation may be necessary to solve this problem. Temperature sensors are used to measure the temperature of the displacement transducer and correct the output signals accordingly.
It is important to note that the specific challenges and solutions may vary depending on the specific application and requirements of the transducer. It is recommended to consult the manufacturer's instructions and specifications for the specific displacement transducer and, if necessary, obtain support from the manufacturer or specialist personnel.
