Frictional Type Torque Sensor System
FGDH-3A 

Frictional type torque sensor system FGDH-3A employs a frictional-type gauge does away with having to adhere a strain gauge and time-consuming connection of lead wire. IT measures torque occurring at the drive shaft of an automobile and sends the digital data wirelessly. It uses the 2.4 GHz range of the wireless range for long-range communication and easy receiving antenna locationing. The sensor clamps around the shaft and screws down easily. Applicable shaft diameters are ø20 to 30 mm, ø30 to 40 mm, and ø40 to 50 mm. Power supply uses a USB power cable with recharging capability, so the sensor can be recharged without needing to be removed.

AW series High temperature Weldable strain gauge

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

Display Unit TMR-381

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.
