　　1、 Overview of LMC-200 type force measuring anchor rod:

　　The force measuring anchor rod, also known as the anchor rod dynamometer, is an instrument used to measure the changes in the force on the anchor rod. It can determine the load borne by the tail of the anchor rod by measuring the hydraulic pressure of the hydraulic pillow. By monitoring the anchor rods, the quality of anchor rod support can be monitored to achieve the purpose of monitoring the stress of the surrounding rock in the tunnel.

　　2、 Technical specifications of LMC-200 force measuring anchor rod:

　　⑴ Range: 0-200KN;

　　⑵ Resolution: 0.1KN;

　　⑶ Accuracy: 1.5% FS;

　　⑷ Operating environment: 0-40 ℃, 95% RH underground in coal mines.

　　3、 Technical characteristics of LMC-200 force measuring anchor rod:

　　This force measuring anchor rod belongs to the specialized force measuring device for mining and geotechnical engineering, and is a monitoring instrument for measuring the force changes along the entire length of the anchor rod. The anchor rod is mainly composed of resistance strain gauges (sensors) and handheld collectors. The resistance strain gauge fixed on the anchor rod will sense the stress changes and read the output value (kN) through a handheld collector. Its characteristics are small size, light weight, stable performance, and easy installation and carrying.

　　4、 Working principle of LMC-200 type force measuring anchor rod:

　　Within the elastic limit, the elastic force of a spring is directly proportional to its deformation (elongation or compression value). Writing: F=k'x

　　Among them, "F" represents the elastic force of the spring, which is the force exerted on the object when the spring deforms.

　　（1）“x”， It is the length of the spring that extends or shortens. Note that "x" is based on the length of the spring when it does not deform, that is, x=x '- xq or x=Xo ← x'.

　　（2）“k”， It is called the stiffness coefficient of a spring, which describes the magnitude of the elastic force generated per unit deformation. A large k value indicates that a large force is required per unit length of deformation, or that the spring is "hard". K is related to the spring material, length, thickness, etc. The international unit of k is N/m.

　　(3) If several identical springs are connected in series or parallel, the stiffness coefficient of this new spring is no longer the same as the original stiffness coefficient.

　　If two springs with a stiffness coefficient of k are connected in series to form spring 1, and their stiffness coefficient is k, then F=ki * x. Since the elastic force at each point is F, the stiffness coefficient of spring 1 can be written as ko when two springs with the same stiffness coefficient and original length are connected in parallel, and the reading of F=k2. x becomes smaller.

　　Similarly, the reading increases after parallel connection.
