Upgraded Backing Materials of Metal Foil Strain Gauges

BCM SENSOR has recently successfully upgraded the materials of the backing layer of its metal foil strain gauge from FIBA to FIBAL:

- F: modified phenolic resin
- I: modified polyimide resin
- B: laminated polyetherketone
- A: advanced laminated polyimide
- L: laminated polyimide

Thanks to the different backing materials, the strain gauges from BCM SENSOR can have different working temperature ranges as listed below:

- F: -30~+80°C
- I: -85~+150°C
- B: -45~+150°C
- A: -195~+200°C
- L: -55~+150°C

These wide working temperature ranges can meet the requirements of various applications, from commercial and normal industrial applications to automotive and military applications.

Both backing A and L are laminated polyimide. The gauge with backing A features the widest working temperature, while the gauge with backing L can have the highest strain limit up to 40,000με.
