Force Sensor Mechanical Sensors Are Now Used

Sinocera Piezotronics, INC | Updated: Jul 12, 2017

Force Sensor Mechanical sensors are now used

Real life in the presence of powerful, the interaction between objects generated force. Often people will need to measure the size of the force, similar to the thrust thrust, etc., because the force is a direction of the size of the vector, we need to measure the force when the physical signal into a measurable electrical signal output device , That is, mechanical sensors based on the device, the same size according to the size of the force, the application of different environmental requirements, and now there are a lot of mechanical sensors. Weighing sensors, tension sensors, torque sensors, etc. These mechanical sensors are now widely used.

For each of the different applications, there are different types of sensors in each branch of the mechanical sensor. There are many types of targeted sensors that are now used in industrial machines to measure tension sensors. The tension sensor is based on the principle of the load cell, using two tension transmission parts to force the internal structure of which the force sensitive device is fixed, the piezoelectric pads are pressed on one side in the central area of the piezoelectric sheet, The other side of the chip and the edge of the force between the part and close to the piezoelectric film. According to the different strength and size of the design of the appearance of different tensile sensors, S-type tensile sensors, plate ring tension sensors and so on. S-type tensile force sensor is the most common sensor in a sensor, most of which is used to measure the tension and pressure between the solid, which is also commonly known as the pull pressure sensor, because its shape like S shape, so habit Also known as S-type tension sensor, which has the advantage of easy installation, easy to use, suitable for hanging scales, batching scales, machine scales and other electronic force measurement system. Plate ring tension sensor is also the name of the name of the name, and it The advantages are more suitable for a large range of work under harsh conditions, frequency response characteristics, and many are used in building materials, cement, chemicals, lifting, lifting industry.

There are more types of tension sensors, as well as similar internal spiral external column tension sensor, hook scale sensors, etc., but they also use a principle, the role of force to produce deformation, so that the physical signal into electrical signals. Because the tensile force measurement form is more, and in order to more convenient to directly measure the size of the pull pressure, so the structure of the tension sensor has different changes, but the shortcomings of these changes is different tensile force sensor accuracy is a change, So in the choice of tension sensors, the integrated accuracy and range is the most important indicator. Load cell and load cell installation considerations which? I believe many of my friends on this issue is not very understanding, then we can not work in our work, in order to carry out our work efficiency, we We have to improve our load cell and load cell sensors have a certain understanding of the installation. Next, let's take a look at how the engineers of Shenzhen Lecture Technology Co., Ltd. introduced it?

In order to ensure the accuracy of the load / load cell, there are still some problems in the installation and use process. Note that the installation and use of the load / load cell should pay attention to the following details to ensure that the load / sensor measurement accuracy and use life:

1, force / load cell to gently, especially for the use of aluminum alloy as an elastomer small capacity sensor, any vibration caused by the impact or fall, are likely to cause a large output error.

2, the design of the loading device and installation should ensure that the load force of the line and force / load cell force axis coincidence, so that the impact of tilting load and eccentric load to a minimum.

3, in the level of adjustment. If you are using a single load cell / load cell, the mounting surface of the base should be adjusted to the level using the level; if the sensor is measured simultaneously, the mounting surface of the base should be kept as far as possible on a horizontal plane, The purpose of this is mainly to ensure that the power of each sensor is basically the same.

4, according to its description of the load / load cell range selection to determine the rated load of the sensor used.

5, the sensor pressure sensor base mounting surface should be as smooth and clean, without any oil or film, etc. exist. The mounting base itself should have sufficient strength and rigidity, usually requiring higher strength and rigidity than the sensor itself.
