Working principle
The load sensor mainly uses the elastic deformation of the columnar elastic body under the action of external force, so that the resistance value of the strain gauge pasted on its surface changes (increases or decreases), and then converts this resistance change into an electrical signal (voltage or current) through the corresponding measuring circuit, thus completing the testing process.
Details
Excellent alloy steel material
Using high-quality alloy steel, after quenching, the hardness is high. The nickel-plated anticorrosion layer has good corrosion resistance and can maintain long-term stability in harsh external environments.
Application scenarios
Usage and precautions:
(1) When determining the sensor specifications, it is recommended to select 80% of the rated load.
(2) When designing the 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 force.
(3) Sensor cable wiring markings:
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 and starts working, it must be preheated, and the instrument must be stable before starting work. When performing long-distance measurements, the grounding wire shield must be grounded after being connected to the system.
(5) The sensor housing, protective cover plate, and lead connector are all sealed. Please do not open them arbitrarily.
(6) The sensor storage environment should be dry and free of corrosion. Avoid using the sensor near high non-working heat sources.
