QF series strain gauges for high temperature use

These are foil strain gauges having a polyimide resin backing.  Strain measurement in high temperature is easily performed by bonding the strain gauge with room temperature curing adhesive NP-50B.  Strain gauges for stress concentration measurement or torque measurement are also available in addition to general use gauges in this series. 
New series of strain gauges named GOBLET are added to this series.  They are compliant with RoHS 2 Directive 2011/65/EU and supplied with CE marking.  Even though lead-free solder is used in the GOBLET gauges, they show better performance than conventional strain gauges owing to the adoption of unique gauge pattern.  Extension leadwires with CE marking are also available.
