Class-C Strain Gauges
for Stress Analysis
BCM class-C
gauges are specially designed for application of stress analysis to be
performed in some critic measurement conditions, like high temperatures
(up to 250 °C), water proof, or high elongation.
As long as temperature
induced error is not so important that it is not necessary to take into
account temperature compensation, the class-C strain gauges are recommended
to use for stress analysis in above-mentioned critic measurement conditions.
The class-C gauges are organised in gauge
part numbers (P/N). In order to choose a proper gauge according to gauge
P/N, we suggest you first refer to
Strain Gauge Coding System
for a quick selection of the correct gauge.
Following tables list all class-C gauges available in stock
for quick delivery.
