Strain Gages BHB, BAM, and BAB250

Strain Gages Standard

Products Specifications

BE Series

Fully encapsulated Constantan foil gages, phenolicacetal backing and self-temperatu recompensation. With good flexibility, stable performance and easy bonding, are suitable for general transducers (Class 0.05) and stress analysis.

BA Series

Fully encapsulated Constantan foil gages, polyimide backing and self-temperature compensation. With high elongation, excellent heat-resistance and wide temperature range, are mainly used for precise stress analysis and normal accuracy transducers with temperature up to 150℃.


BQ Series

Constantan foil gages with thin and f lexible paper-based acetal backing, without selftemperature compensation, are easy bonding and handling. It is widely used for general stress analysis, especially for composite material sand cement structures.

Note:

1. BA Series strain gages are classified into two-temperature groupes at normal temperature (within 80℃) and moderate temperature (within150℃ ). It should be mentioned in your order. For example, BA350-3HA (11) is in normal temperature, BA350-3HA (11) 150 is in moderate temperature.
2.Both BE and BQ series are classfied into gages with temperature self-compensation and gages without temperature self-compensation.For example, BE120-3AA (11) is temperature self-compensated and BE120-3AA is non-temperature selfcompensated.
3. For encapsulated gages with grid pattern HA-D and HA-E, we only offer gages with lead wire forms.
4. Except for the models listed in above table, we also can produce hight precision transducers that use strain ages with any shape and size according to samples or drawings supplied by customers.
