Frictional type Axial Strain Transducer

Frictional type Axial Strain Transducer FGAH-1B-R／FGAH-1B-H

This transducer measures axial strain of steering tie-rod of a car and consists of two types FGAH-1B-R and FGAH-1B-H for which a cross section of the rod is round shape or hexagon's. It is also suited to measure axial strain of a tension rod used in aseismic reinforcement structure or in steel frame structure. Since frictional strain gauges are used in this transducer, installation is completed and it gets ready for measurement by merely pinching the rod with the transducer, without detaching the rod. There is no need of technical skill and complicated works for attaching strain gauges on the rod.

Frictional type Axial Strain Transducer FGAH-1B-R／FGAH-1B-H
Features
  • Easily installed by just clamping-on without detaching the existing rod
  • Tensile force management of rod between sheet piles or in architectural structures is easily achieved

Junction Box

Junction Box JB-2/JB-4

This junction box is used to connect two or four strain gauge type transducers and average the outputs of those transducers. The mean value is easily measured by a digital indicator or data logger. 
It can also be used as a branching box to divide the connection of switching boxes into two or four series.

Junction Box JB-2/JB-4

    Type JB-2/JB-4
    Number of input points JB-2 : 2
    JB-4 : 4
    Dimensions 80(W) x 50(H) x 120(D)mm
    Weight Approx. 220g

Examples of use

Example of use as an input averaging junction box

img-jb-2-4-02

・Strain gauge type transducers to be connected must be of the same capacity, rated output and input/output resistance
・The input/output resistance viewed from the instrument is as follows.
   (Input/output resistance of one transducer) divided by (Number of connected transducers).
   The calculated value above must be within the range of the instrument specification.

Example of use as a branching box

img-jb-2-4-03

As the inside of the junction box is wired with 7 wires (for terminals A to G), the junction box can also be used as a branching box as the above. Each connection between the data logger, junction box and switching boxes must be made using an exclusive 7-core cable specified by us.

Stress Gauge

SF series Stress gaugeCE

These gauges are intended to measure the stress in an optional direction of the specimen in plane stress field. The gauges are sensitive not only in these axial direction but also in the transverse direction, and the sensitivity ratio of the transverse direction to the axial directions is equal to the Poisson’s ratio of the specimen material. In addition, the gauges are not sensitive to the shearing strain. Accordingly, the output of the gauges is proportional to the stress in the axial direction. The gauges are available in three types depending on the Poisson’s ratio of the specimen material.

Crack Detection Gauge

FAC series Crack detection gauge

FAC series crack detection gauges are designed to measure the length and propagation speed of cracks occurring as a result of metal fatigue in machinery, ships, aircraft, and automobiles. A gauge is adhered beforehand where cracks have occurred or are predicted to occur. As a crack progresses, the grid lines separate one after another, and output value changes. Use together with the special adaptor CGA-120B.
