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.
