Tension system module PFVO143
PFVO143 Tension Amplifier is an instrument specifically designed for measuring and amplifying the internal or surface tension of objects. It operates based on the principle of an electric bridge and consists of a circuit consisting of four resistors and a sensor. Sensors are usually strain gauges or pressure sensors that can detect the deformation or external force of an object.
When an object undergoes deformation or force, the resistance value of the sensor will undergo slight changes. These small changes can cause changes in the resistance value of the bridge, thereby affecting the magnitude of the voltage signal. In order to amplify the small changes in the sensor, it is necessary to adjust the bridge. In a tension amplifier, the positive and negative input terminals of the operational amplifier are connected to the connection points of the two central branches of the bridge, respectively. The output terminal of the operational amplifier is connected to a negative feedback resistor, and the other end of the resistor is connected to the negative input terminal of the operational amplifier. The resistance value of a negative feedback resistor is usually determined by the resistance value of the regulating resistor.
The PFVO143 tension amplifier is widely used in force measurement and control systems in engineering and scientific fields, and has the following main functions:
Material testing: In the testing of materials such as metal, plastic, and rubber, it is often necessary to use a tension amplifier to measure and record information such as tensile load, bending load, and compressive stress of the material.
Medical health: In the medical field, PFVO143 tension amplifiers are also widely used. For example, when implanting plant stents in the body, tension amplifiers can help ensure uniform tension of the stent and help doctors evaluate the stability of the stent in the body.
Process control: During the manufacturing process, PFVO143 tension amplifier can help operators grasp important parameters of product production, so as to adjust the production process in a timely manner. For example, in the textile industry, tension amplifiers are applied to measure yarn tension to ensure consistency in the quality and size of the produced yarn.
In addition, when debugging equipment such as the transmission system of the coating machine, attention should be paid to avoiding exceeding the maximum tension that the tension amplifier can withstand, in order to prevent overload or abnormal vibration from occurring. At the same time, attention should also be paid to preventing equipment from being affected by external factors such as temperature changes and electromagnetic interference.
The use of PFVO143 tension amplifier mainly includes the following steps:
Check equipment and power supply: First, ensure that all equipment and power supply are functioning properly and connected to the correct power outlet. At the same time, check if the working environment meets the requirements to avoid affecting the smooth installation of the equipment.
Preparation for startup: Before starting up, make sure that all devices are wired properly and plug the power plug into a power outlet.
Connect the tension sensor: Connect the tension sensor to the corresponding device and secure the sensor with screws.
Starting the device: Press the power switch and the device will start, displaying “READY” and “100%” on the screen.
Setting mode: Press the “SET” button to enter the setting mode. A series of numbers will be displayed on the screen, indicating that the device has entered setup mode.
Calibration program: Press the “%” button, the device will automatically enter the calibration program, and adjust internal parameters based on the measured tension value.
Save parameters: Press the “SET” button to save the set parameters and return to normal working mode. When the device is in normal working mode, the measured tension value will be displayed on the screen. If it exceeds the set range, the device will automatically adjust the parameters.
Change parameters: When the device is running, if there is a need to change parameters, you can press the “SET” button to enter the setting mode, change the corresponding parameters, and save to return to normal working mode.
During use, the following points should be noted:
Avoid overload: Avoid exceeding the maximum tension that the tension amplifier can withstand to prevent overloading or abnormal vibration of the coating machine transmission system.
Prevent interference: Pay attention to preventing equipment from being affected by external factors such as temperature changes and electromagnetic interference, especially in high-temperature environments or near strong magnetic fields. Strengthen equipment protection and protective measures.
Check the circuit: Before calibrating and adjusting the tension amplifier, it is necessary to first check whether the circuit is normal, including whether the power supply voltage is stable, whether the power switch is turned on and off normally, and whether the signal transmission cable is in good condition.
