Tension sensor, also known as tension detector, is an instrument used to detect yarn tension in the process of tension control. In essence, the tension sensor is also a load cell.
Structure and working principle:
The principle of the tension sensor is based on the weight sensor, the use of two tension transfer components to transmit force, the internal structure of the force sensor is fixed in the center area of the piezoelectric plate on one side of the piezoelectric plate gasket, the piezoelectric substrate is located between the other side edge and the force transfer part and close to the piezoelectric plate. Tension sensor according to its working principle can be divided into strain gauge type and micro-displacement type,
Strain gauge type tension sensor is the tension strain gauge and compression strain gauge in accordance with the bridge connected together, the resistance value of the strain gauge will change with the change of external pressure, the change value depends on the size of the pressure.
The micro-displacement tension sensor is through the external force to apply the load, so that the plate spring displacement, and then through the differential transformer to detect the tension, because the displacement of the plate is very small, so called micro-displacement tension detector.
According to the strength and size of different tension, tension sensors of different shapes are designed, such as S-type tension sensor, plate ring tension sensor, etc. The S-type tension sensor is the most commonly used mechanical sensor that uses dry to measure most of the tension and pressure in a solid, often called a tension pressure sensor because it looks like an S-shape, so it is called an S-type tension sensor used on it.
The tension sensor mostly uses a three-wheel style structure, in order not to affect the operation of the cable, so in the design also achieved a solid and compact principle design, measurement repetition is good, high accuracy, easy installation is the design characteristics of the base two-wheel style, and the mobility of the center wheel will dry installation and operation.
Applications:
Mi force sensors have been found in many lines today and have been widely used, especially in the field of industrial production measurement. The advantage of the tension sensor is that it is simple to install and makes the household
Moreover, it is suitable for hanging scales, weighing machines, modified scales and electronic force measuring systems. Ring tension sensor plate because of the same name and more suitable for a large range, bad working ring competition, good frequency response, many with dry building materials, cement, chemical, lifting, lifting and so on.
In addition, tension sensors are also used in the paper industry, pharmaceutical, chemical, food, steel mills, foil production plants, cable laying and sawmills and other machines, which require batch processing
The use of high quality hydraulic components and instruments.
A typical application of tension sensors in the pharmaceutical field is to weigh stirring containers that handle the corresponding prescription during processing in a factory. And in the printing industry, tension sensing
According to the collection of paper tension signal to the controller, and the controller according to the signal to adjust the unwinding and winding speed to achieve the balance of tension, and save the cost of waste and increase the output. In the printing press, it is necessary to detect the printing register, the amount of ink and water, the paper failure and other tests. And it uses the displacement type. Tension sensor installation:
The installation of the tension sensor is divided into two types, the first is to use the bearing seat fixed with a bolt hole to fix the bearing seat on the base. The other is to use the optional plate fixed bearing
When installing the method, it is important to pay attention to the causes of inaccurate tension measurement, when the tension sensing device is connected to the signal line, the switching quantity and the output terminal are weak and pure
Try to stay away from strong wires, so as not to interfere with electromagnetic signals on tension detection. In practical application, the output sensitivity, temperature compensation range, zero temperature shadow direction, rated load, limit conformity and other factors are also the reasons that affect the inaccurate tension measurement. Precautions for use:
1. The screws for installing the tension detector and bearing seat should not be too long, which will cause the reed of the tension detector to fail to work properly and no tension can be detected.
2. When using side fixing, the fixing screws should not be too long, otherwise it will cause damage to the measuring mechanism in the tension detector.
3. The tension detector should not be strongly impacted or harmed at any time, otherwise it will cause damage to the tension detector.
