Temperature-integrated strain gauges (with thermocouple)

Temperature-integrated strain gauges (with thermocouple)

These are temperature-integrated strain gauges having our unique thermocouple added. F series and almost all other foil strain gauges can be fitted with this capability. The temperature contact is a tab on the strain gauge, and displays the same temperature as the strain gauge. This can be measured with any of our data loggers.
* Data loggers applicable to the measurement of these gauges are TDS-540/-530/-303/-300/-630/-602/ -601A/-601/-102/-101R and TC-32K/-31K. Measurement using a dynamic strainmeter is not possible.

Slip-ring type Wheel Torque Measurement LTW-NA

Slip-ring type Wheel Torque Measurement LTW-NA　2.5kN・m

This is a torque transducer for measuring driving torque and braking torque while an automobile is traveling. Torque can be measured with analog output by connecting the slip-ring and dynamic strainmeter that come standard. The slip-ring has a built-in encoder, allowing an F/V converter to be connected for counting output pulse and thereby measure rotational velocity. Preparing a special rim and hub adapter also allows the torque transducer to be installed to any passenger automobile.

Low Elastic Strain Gauge Wood, Gypsum Use LF series Strain gauges for Wood and Gypsum

LF series Strain gauges for Wood and Gypsum

LF series strain gauges for wood and gypsum are foil gauges utilizing special plastic for the backing. The grid pattern is suited for measurement on materials having a low elastic modulus and reduces the stiffening effect of the strain gauge on the specimen. Gauges are self-temperature-compensated for 11×10-6/℃ materials.
A new series of strain gauges bearing the CE mark, GOBLET, has been added. This CE-compliant series of products is compliant with RoHS directives. These gauges exceed the capabilities of conventional strain gauges with lead-free soldering as well as a unique tab design. CE-compliant extension lead wires are also available.
