Shandong Core Future A-OFF100 six-axis force and torque sensor

describe

The A-OFF100 fiber Bragg grating anchor axial force sensor uses the principle of fiber Bragg grating microstrain measurement to measure axial force. Through special structural design and process packaging,fiber gratings are welded on the internal structural parts of the sensor. When the upper and lower surfaces of the product are subjected to axial force,the internal structure undergoes micro-strain,causing the fiber grating wavelength to be linearly proportional to the axial force to achieve Measure axial force.

This product is mainly developed and designed for the axial force measurement of anchor bolts. It is currently mainly used in metallurgy,coal mines,tunnels and other industries to detect ground stress after rock and soil excavation,and is used in conjunction with the BA-FT series fiber optic sensing demodulators. Connectivity enables online monitoring and measurement.

Features

• Characteristics of fiber optic sensors: intrinsically safe,free from electromagnetic interference,corrosion-resistant,anti-pollution,and lightning-strike resistant,and can be used under harsh conditions such as strong electromagnetic interference,high lightning strikes,flammable,and explosive;

• It is generally installed several meters to hundreds of meters underground. If the temperature changes very little throughout the year,temperature compensation is not required. Temperature sensors can also be installed for compensation to improve measurement accuracy;

• The layout is simple and can be mixed with other types of optical fiber sensors in series or parallel to improve the utilization of the demodulator.

• Commonly used demodulator for other types of sensors,with good compatibility;

• Using metallized grating,the zero point is stable;

• It can replace traditional bolt washers and be used directly,making installation and maintenance easy;

• High precision,high stability and high reliability.
