How it works
The load sensor mainly utilizes the elastic deformation of the columnar elastic body under the action of external force to change the resistance value of the resistance strain gauge attached to its surface (increase or decrease), and then converts this resistance change into an electrical signal (voltage or current) through the corresponding measurement circuit, thereby completing the test process.
Details
Excellent alloy steel material
Made of high-quality alloy steel, it has high hardness after quenching. The nickel-plated anti-corrosion layer has good corrosion resistance and can maintain long-term stability in harsh external environments.
Application Scenario
Usage and precautions:
(1) When determining the sensor specifications, it is recommended to select 80% according to the rated load.
(2) When designing a loading device, the user should ensure that the line of action of the loading force coincides with the force axis of the sensor to avoid measurement errors caused by lateral forces.
(3) Sensor cable wiring mark:
A: Sensor: Power supply +: red, power supply -: blue
Signal +: yellow, signal -: white
B: Amplifier: Power supply: Red, Common terminal: White (blue)
Signal: Yellow
(4) After the sensor is connected to the power supply, it must be preheated and the instrument must be stable before starting to work. When making long-distance measurements, the lead shielding layer must be grounded after being connected to the system.
(5) The sensor housing, protective cover, and lead connector are all sealed. Please do not open them at will.
(6) The sensor should be stored in a dry and corrosion-free environment. Avoid using the sensor in an environment close to high non-working heat sources.
