What is GOBLET series

A strain gauge is constructed so that the gauge leads to conduct electrical signal are connected by soldering to the metal foil which is called gauge element.  The solder is an alloy composed of lead and tin.  Since lead is not only harmful to human bodies but may cause adverse effects on the natural environment, we have developed a strain gauge using lead-free solder.  It is known that the use of lead-free solder may result in a shorter fatigue life of the strain gauge compared to a strain gauge using conventional solder including lead.  To overcome the problem, we have developed a strain gauge having a unique gauge pattern and special plastics backing.  With the use of lead-free solder for the connection of gauge leads, the strain gauge of this configuration shows a fatigue life equivalent to that of conventional strain gauges.  Most of general purpose strain gauges in our strain gauge series F are available in this configuration, and they are supplied as RoHS compliant products with CE marking.  
We have given a name GOBLET especially for the strain gauges, as the pattern looks like a goblet.  GOBLET is also an abbreviation of “Gauges Of Brilliant Lifespan and Environmentally Thoughtful”, which represents the excellent fatigue life and small environmental effect of the strain gauges and expresses the concept of development of the strain gauges. 
Owing to the use of special plastics for the backing, operational temperature range of the gauges has been improved to -196 to +150°C.  Integral leadwires for instrumentation are available using lead-free solder and in various types to meet usage conditions. 
We will keep extending the GOBLET to other series of our strain gauges, not only to satisfy the needs for strain gauges but to meet environmental requirements including effective use of natural resources.
