The most commonly used tension sensor is resistance strain, which is a rugged, durable and reliable sensor product. In order to ensure its accuracy, there are still some problems to be aware of during the installation and use. The following is a brief introduction.

1. The tension sensor should be handled lightly, especially for small-capacity sensors that use alloy aluminum as the elastomer. Any shock or drop caused by vibration is likely to cause a large output error.

2. Design the loading device and the installation should ensure that the action line of the loading force coincides with the force axis of the tension sensor, so that the effects of the tilt load and the eccentric load are minimized.

3. In terms of level adjustment. If a single tension sensor is used, the mounting plane of the base should be adjusted to the level using a level; if multiple sensors are simultaneously measured, the mounting surface of the base should be kept at a level as much as possible. The main purpose is to ensure that each sensor is basically the same.

4. Determine the rated load of the sensor used according to the range of the tension sensor in this description.

5, the base mounting surface of the sensor should be as smooth and clean as possible, without any oil or film. The mounting base itself should have sufficient strength and rigidity and typically require strength and stiffness above the sensor itself.

6. The sensor case, protective cover and lead connector are sealed and the user is not allowed to open.

7, to prevent chemical corrosion. Vaseline should be used to apply the outer surface of the tension sensor during installation. Avoid using direct sunlight and drastic changes in ambient temperature

8. If it is unavoidable, install protective or mitigation devices.

9. In order to prevent the large current from directly licking the sensor body and damage the sensor, it is forbidden to carry out the welding work after the sensor is installed.

10. Add a bypass device made of copper braided wire at both ends of the tension sensor loading device.

11. The cable should not be lengthened by itself. When it is really necessary to lengthen, it should be soldered at the joint and add moisture-proof sealant.

12. It is best to use a number of baffles around the tension sensor to cover the sensor. The purpose of this is to prevent debris from falling into the moving part of the sensor and affecting its measurement accuracy.

13. The cable of the sensor should be away from the strong power supply line or the place with pulse wave. When the competition cannot be avoided, the cable of the tension sensor should be inserted into the iron pipe separately, and the connection distance should be shortened as much as possible.

14. According to the range of the tension sensor in this description, determine the rated load of the sensor used. Although the tension sensor itself has a certain overload capacity, it should be avoided as much as possible during installation and use. Sometimes overloading for a short period of time may also cause permanent damage to the sensor.

15. In the case of high precision use, the tension sensor and instrument should be used after 30 minutes of warm-up.

16. The sensor should be placed in a dry, ventilated, non-corrosive atmosphere.

The installation and use of the tension sensor should pay attention to these details. Why the sensor used is not bad for a long time, and some have never had a problem. After reading the above introduction, you may understand it.
