Wide Application of Potentiometers

We all know that the potentiometer is a variable resistor, which consists of a resistor body and a sliding system. By changing the position of the moving contact on the resistor through a sliding system, a voltage or current signal output that is related to the position of the moving contact can be obtained. Potentiometers have a history of over a hundred years since their birth. As a fundamental electronic component, they are widely used in a variety of control or feedback applications. Potentiometers are used for as small as the brightness adjustment of desk lamps, fan speed adjustment, and audio volume adjustment, as large as for providing feedback on vehicle angles, crane arm positions, and precise positioning of robotic arms.

The Importance of Potentiometers

It is because of the wide application of potentiometers that they are too common. The market is full of various brands of varying quality, which create an impression of low precision, short life expectancy and low value for potentiometers. Are potentiometers really low-end products? No! In fact, in many specific situations, only potentiometers can still be used today. It cannot be replaced by such as optical encoders, magnetic encoders, rotary encoders, etc. And a precision and reliable potentiometer is the cornerstone to ensure the reliable operation of the equipment.

Angular Displacement Potentiometer Comprehensive Test Bench Comes into Being

How to obtain an accurate and reliable potentiometer? Sibo has always insisted on rigorously testing potentiometers.

The main technical indicators of a potentiometer include total resistance, effective electrical stroke, linearity accuracy, compliance, sliding noise, contact resistance, contact resistance variation, output smoothness, clearance, etc. There are also various standardized documents defining these main technical indicators. However, these main technical indicators are tested separately, which makes the tests of potentiometer performance time-consuming. Some companies will cut corners and eliminate the tests of these technical indicators, resulting in hidden dangers of product quality.

As one of the earliest companies to launch potentiometer products in China, Sibo has been dedicated to studying and researching the potentiometer industry for 29 years and has a profound understanding of the main technical parameters of potentiometers. In 2023, Sibo summarized and integrated experience to develop the "SE-RP100 Angular Displacement Potentiometer Comprehensive Test Bench". This test bench was developed with reference to GB/T 15298-1994, GJB1865A-2015, IEC60393-1, QSB 4.00-2021, QSB1.01-2022 and other standards. It can be used for comprehensive testing of angle displacement potentiometers, to meet various testing and quality control needs of enterprises for potentiometers during production and use.

Function Introduction

The SE-RP100 Angular Displacement Potentiometer Comprehensive Test Bench mainly includes total resistance test, effective electric stroke test, independent linearity test, sliding noise test, contact resistance test, contact resistance change test, output smoothness test, and clearance test and other functional tests. It can test various kinds of angular displacement potentiometers such as wire-wound potentiometers, conductive plastic potentiometers, single turn potentiometers, and multi turn potentiometers. In addition to these common potentiometer performance tests, "absolute linearity test" and "absolute compliance test" can also be conducted according to customized requirements.

Characteristics Introduction

The SE-RP100 Angular Displacement Potentiometer Comprehensive Test Bench has high integration, high measurement precision, high automation, and good test repeatability. Test items can be selected, test item indicators can be set, test results can be automatically judged, and test reports can be automatically generated according to users’ testing needs. It is easy to operate, and can be also customized for special testing requirements.

1. High precision: The equipment uses high-precision and high-resolution power supply and measurement and acquisition system internally, with an accuracy of over 0.01%, to greatly reduce the data errors caused by equipment accuracy during product testing.

2. Good repeatability: Using high-precision direct drive motors, the repeatability can reach within ± 5 inches, to effectively ensure the consistency of testing.

3.    Standardization: The testing methods for each test item are designed according to the national standard methods to ensure the accuracy of the testing methods.

4.    Easy to operate: The equipment can test all test items at one time, and the test items can be selected. The test results are automatically saved, and test forms can be generated automatically.

5.    Customizable: According to the requirements of different users and scenarios, the equipment can choose different configuration requirements such as single station, dual station, stop position, single circle, multi circle, etc. We can also customize various special fixtures according to customer needs, such as terminal connections.

Professional Verification

In order to verify the accuracy and reliability of our equipment, we have invited a third-party company to conduct strict calibration. The test results show that our equipment is highly consistent with the testing results of laboratory equipment for various indicators of potentiometer products. It is worth mentioning that many laboratories lack the corresponding equipment and instruments for detecting the indicators of "sliding noise" and "clearance". But the SE-RP100 test bench can accurately measure these two indicators, demonstrating its unique advantages and becoming one of the few equipment in the market that can accurately detect these two indicators. This not only proves the high precision of our equipment, but also fully demonstrates the in-depth analysis of product characteristics and technical requirements by our engineering team. It also reflects the accumulation of experience and technical precipitation of Sibo Company in the potentiometer industry for nearly 30 years.

Industry Recognition

In addition, we also compared the test results of SAKAE, a global manufacturer of high-end potentiometers, and the results showed that our equipment also highly complies with it. This fully proves that the accuracy level of the SE-RP100 test bench can be comparable to international top equipment. We have also invited many industry friends from home and abroad to come to test. Their feedback was equally positive, giving high praise to our equipment. They believe that SE-RP100 technology is leading and easy to operate, greatly improving the testing efficiency and accuracy of potentiometer products.

Time-limited Benefits

The SE-RP100 angular displacement potentiometer comprehensive test bench is becoming a new benchmark for potentiometer testing equipment with its excellent performance and internationally standardized accuracy.
