These strain gauges have strain sensing elements fully encapsulated in corrosion-resisting metal tubes (except for AW-6). They are suited to use in various environment including in liquids or gases. Installation is easily done using dedicated spot welder W-50R/W-50RB
By the connection of display unit TMR-381, stand-alone control of multi-recorder becomes possible such as setting of various units, measurement control (balancing / measurement start and stop / automatic measurement setting), monitoring (T-Y sweep / Y-T cont. / X-Y / numerical) and setting file management. When dedicated I/F cable is used for connection, external power source is not required because this unit is operated by the power supply from the control unit TMR-311. It is also possible to use a LAN cable for connection. In this case, extension is possible up to 100 meters and a USB mobile battery can be used as the power source.
Since the display unit operates independently of the control unit, measurement will be continued even if the display unit is turned off after the automatic measurement is started. The display unit may be connected only for confirmation of data and/or stop of measurement.

More Information
This is a small acceleration transducer suitable for measurement of vibration mode of machines and structures including cable tension of bridges. High sensitivity of 30000 x 10-6 strain for 10 m/s2 makes minute vibration measurement possible.
Protection ratings : IP 61 equivalent
| Type | Capacity | Rated output | Non-linearity | Temperature |
|---|---|---|---|---|
| ARS-10A | 10 m/s2 | Approx. 15m V/V(30000 x 10－6 strain) | 1％RO | -10 to +50 ℃ |
Measurement moves in the plus direction when acceleration occurs in the acceleration transducer itself toward the “+” mark on the casing.
More Information
This is a transducer to measure axial strain of tie-rod of a car. It is also suited to measure axial strain of 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 or complicated works for attaching strain gauges on the rod. It is applicable either to round rod or hexagonal rod by replacing the spacer and fixing bracket.
