Characteristics of type I tension pressure sensor:
(1) Linearity: refers to the degree that the actual relationship curve between the sensor output and input deviates from the fitting straight line. It is defined as the ratio of the maximum deviation value between the actual characteristic curve and the fitting straight line within the full range to the full range output value.
(2) Sensitivity: sensitivity is an important indicator of sensor static characteristics. It is defined as the ratio of the increment of the output quantity to the increment of the corresponding input quantity that causes the increment. The sensitivity is expressed by S.
(3) Hysteresis: The phenomenon that the input and output characteristic curves of the sensor do not coincide during the change of input quantity from small to large (positive stroke) and from large to small (reverse stroke) becomes hysteresis. For input signals of the same size, the positive and negative stroke output signals of the sensor are not equal, and this difference is called hysteresis difference.
(4) Repeatability: Repeatability refers to the degree to which the characteristic curve obtained by the sensor is inconsistent when the input quantity is continuously changed in the same direction for multiple times in the full range.
(5) Drift: Sensor drift refers to the change of sensor output with time when the input is constant. This phenomenon is called drift. There are two reasons for drift: one is the structural parameters of the sensor itself; The second is the surrounding environment (such as temperature, humidity, etc.).
Several common types of tension and pressure sensors:
1. S-type tension pressure sensor;
2. Z-column tension and pressure sensor;
3. L-type high-precision tension and pressure sensor;
4. U-type tension pressure sensor;
5. ZT column tension and pressure sensor;
6. ZX type pin type tension and pressure sensor;
7. Type B pull plate type pull pressure sensor;
8. D-type tension pressure sensor;
9. X-type cantilever tension and pressure sensor;
10. XS pin type tension pressure sensor;
11. XD pin type tension pressure sensor, etc.
Application of tension sensor:
1. S-type tension pressure sensor is applicable to specified standard weighing, such as platform scale, hopper weighing system, etc., especially for some industrial weighing systems requiring high accuracy. Because of its high reliability and sealing design, it can work continuously and stably for a long time even in harsh environment.
2. The column-type tension sensor has the advantages of both column-type and S-type, compact structure, beautiful shape, high measuring accuracy, and strong anti-bias ability. It is widely used in metering and control systems such as batching, mechanical manufacturing, tensile testing machines, etc.
3. L-type tension pressure sensor has high accuracy, low drift, small volume and strong anti-bias ability, and is widely used in the measurement and control system of small force value.
4. U-type tension pressure sensor has compact structure, convenient installation, high measuring accuracy and strong anti-bias ability, and is widely used in the measurement and control system of tension pressure such as railway signal control, batching, machinery manufacturing, etc.
5. ZT type small column type tension sensor has the advantages of both column type and S type, compact structure, beautiful shape, high measuring accuracy and strong anti-bias ability. It is widely used in metering and control systems such as batching, mechanical manufacturing, tensile testing machines, etc.
6. ZX type pivot pin sensor is a high-precision tension and pressure sensor. It is applicable to all kinds of cranes, hoisting mechanisms, railway signal control, etc. It is widely used in metering control.
7. Type B tension sensor is a pull plate structure, which takes into account the advantages of column type and S type, and has high measurement accuracy. It is widely used in tension testing, measurement and control systems such as batching, machinery manufacturing, cranes, steel cables, ropes, etc.
8. D-type small tension sensor has compact structure, convenient installation, high measuring accuracy and strong anti-bias ability, and is widely used in metering and control systems such as batching, mechanical manufacturing, tensile testing machines, etc.
9. X-type cantilever type tension and pressure sensor has low shape, excellent natural linearity, good lateral force resistance, compact structure, strong anti-bias ability, and overload protection function, which can be used for various electronic scales.
