SPOT WELDER W-50RC

This is a capacitive charge spot welder used for installing weldable strain gauges and fixing lead wires. The welding energy is controlled in 2 ranges of 1~10/5~50 watt second continuously, and a stabilizing circuit cancels the effect of changes in the power source voltage. Projecting parts such as electrical cables is packed inside, it is extremely convenient for field applications.

F series Foil strain gauge

These gauges employ Cu-Ni alloy foil for the grid and special plastics for the backing.  A wide range of operating temperature from -196 to +150°C is possible.  The backing is color coded to identify the objective material for self-temperature compensation.  Strain gauges for stress concentration measurement and residual stress measurement are available in addition to general use gauges.  Leadwire integrated strain gauges are also available with various types of leadwires.  Strain gauges in this series can be supplied with option –F using lead-free solder.  (GOBLET gauges in this series use lead-free solder as standard specifications.)
