High Temperature Use Strain Gauge QF series

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.

Soil Pressure Gauges KDA-PA/KDB-PA

KDA-PA/KDB-PA Soil Pressure Gauge 200kPa to 2MPaCE

These are 200-mm outer diameter soil pressure gauges widely used at construction sites. 
They are designed with a dual-diaphragm structure that can minimize the displacement of the sensing surface when pressure is applied, and thereby keep the stress distribution in the soil undisturbed. KDA-PA and KDB-PA models are available with differing cable exit directions, with KDA-PA used to measure pressure in soil and monitor the behavior of embankments, and KDB-PA used to measure pressure in earth-retaining walls and soil pressure on walls of structures.
