The tension loadcell can directly convert the measured tension into various forms of electrical signals, which is convenient to meet the requirements of centralized detection and control of automation systems, so it is widely used in industrial production.


tension loadcells are widely used in many monitoring and control applications. In addition to direct tension measurement, tension loadcells can also be used to indirectly measure other quantities, such as liquid/gas flow, velocity, water surface or altitude.


At the same time, there is also a class of tension loadcells designed to dynamically measure high-speed changing tensions. Example applications are the monitoring of combustion tension in engine cylinders or the tension of gases in turbine engines. Such sensors are typically fabricated from piezoelectric materials, such as quartz.


Some tension loadcells, such as those used in traffic enforcement cameras, operate in binary mode, that is, when the tension reaches a certain value, the sensor controls the circuit to be turned on or off. This type of tension loadcell is also called a tension switch.


Main applications

1. Applied to hydraulic system

In the hydraulic system, the tension loadcell is mainly used to complete the closed-loop control of the force. When the control spool moves suddenly, a peak tension several times the working tension of the system will be formed in a very short period of time. In typical mobile and industrial hydraulics, any tension loadcell can quickly be destroyed if not designed with such extreme conditions in mind. It is necessary to use a shock-resistant tension loadcell. There are two main methods for the tension loadcell to achieve shock resistance. One is to change the strain gauge chip, and the other is to connect an external coil. Generally, the first method is used in the hydraulic system, mainly because Easy to install. Another reason is that the tension loadcell is subject to constant tension pulsations from the hydraulic pump.


2. Applied to safety control system

tension loadcells are often used in safety control systems, and the main target area is the safety management system of the air compressor itself. There are many sensor applications in the field of safety control. As a very common sensor, it is not surprising that tension loadcells are used in safety control systems.


The application in the field of safety control is generally considered from the performance aspect, the price consideration, and the safety and convenience of the actual operation. It has been proved that the effect of selecting the tension loadcell is very good. The tension loadcell uses the processing technology of mechanical equipment to install some components and signal conditioners on a small chip. So small size is also one of its advantages, in addition, cheap is another big advantage of it. To a certain extent, it can improve the accuracy of system testing. In the safety control system, the tension brought by the compressor is controlled to a certain extent by installing a tension loadcell in the pipeline equipment at the air outlet. This is a certain protection measure and a very effective control system. When the compressor starts normally, if the tension value does not reach the upper limit, the controller will open the air inlet and adjust the equipment to reach the maximum power.


3. Applied to injection mold

tension loadcells play an important role in injection molds. The tension loadcell can be installed in the nozzle of the injection molding machine, the hot runner system, the cold runner system and the cavity of the mold. Plastic tension somewhere between the cavities.


4. Applied to monitoring mine tension

There are many kinds of tension loadcells, and based on the special environment of mine tension monitoring, mining tension loadcells mainly include: semiconductor piezoresistive tension loadcells, metal strain gauge tension loadcells, differential transformer tension loadcells, etc. These sensors have a wide range of applications in the mining industry, and which sensor to use depends on the specific mining environment.


5. Used in compressors, air-conditioning and refrigeration equipment

tension loadcells are often used in air compressors and air-conditioning refrigeration equipment. These sensor products are small in size and easy to install. The tension guide port generally adopts a special valve needle design.
