FAQ#029 – What is the Real Gauge Factor reported in the Specifications and Compliance Certificates of both VW embedded and arc-weldable strain-gauges?
The gauge factors for VW strain-gauges are generic factors calculated from the dimensions and the physical properties of the gauge material. The VW strain-gauges arep roduced in series with industrial method, so each strain gauge is equal to the other: it means that the gauge factor of VW strain gauges do not change. The Gauge […]
FAQ#028 – Are the vibrating wire strain-gauges and spot weldable VW strain gauges equipped with temperature sensors?
Yes, vibrating wire strain-gauges, as well as all other Sisgeo’s vibrating wire instruments, are equipped with a built-in NTC thermistor YSI 44005 type (3000 Ohm at 25°C). Thermistor is included in the instrument price and therefore there is not additional cost for it.
