Instrument serving as the hub of an in-vehicle measurement system
The multi-recorder TMR series is a compact multi-channel data recording system that can easily combine measurement units for all sensor inputs depending on the purpose. Because of its small size and light weight, it is ideal for in-vehicle measurement with limited installation space. In automobile measurement, there are a number of test items such as running performance evaluation test, operability, ride comfort, and safety, using many sensors. Multi-recorder systems have a variety of measurement units that meet these needs.

Selecting strain gauges for automotive, aircraft, industrial machinery, and small strain gauge applications
Our strain gauges are used as a direct measure of the strength of the object being measured. In keeping pace with such applications amid increasingly more sophisticated technology, we have introduced newer and smarter sensors to our lineup. This section introduces a variety of applications in which we have garnered achievements in the automotive, aircraft, and industrial machinery fields, illustrating subjects of measurement and goals. Contact us when making a specific measurement plan, and we will provide details such as how to select and install strain gauges, adhesives, etc.
Ultracompact strain gauges Selection of strain gauges for strain measurement in extremely small locations
Automobiles, personal computers, industrial machinery, and other components require miniaturized printed circuit boards and mounted parts. As a strain gauge for directly measuring their mechanical properties, we have developed a lineup of ultracompact strain gauges that can be installed in a smaller area.

Selecting strain gauges for shear strain and torque measurement
Measure strain occurring at 45 degrees caused by shear stress. Since the gauge size is small, it can be applied to thin springs. The polyimide base allows measurement at temperatures up to +200℃. A standard specification for a coefficient of thermal expansion of 11 × 10-6/℃ is available. We also make self temperature compensated strain gauges according to the coefficient of thermal expansion of other materials.

Selecting strain gauges for stress concentration measurement
A strain gauge with a short gauge length is structured with 5 elements in a row on the gauge backing in order to measure stress concentration. There are two types of gauges (X and Y types), depending on the axial direction of the gauge and the arrangement of the 5 elements, as well as two-element gauges where the two types are in a stacked arrangement. F series gauges allow measuring up to +80℃ and QF series up to +200℃.

Selecting strain gauges for axial force measurement
FLK type, designed with a narrow gauge width, is suitable for adhering axially along bolt shafts, thin pipes, and round bars. Selection can be made from the F, QF, and ZF series depending on the environment it will be used in. QF- and ZF-series standard specifications for a coefficient of thermal expansion of 11 × 10-6/℃ are available. Self-temperature compensating gauges are also manufactured to match the linear expansion coefficient of other materials.
