Class-A Strain Gauges
for Transducer Application
BCM class-A strain gauges are specially developed for manufactureing
precision transducers. For the purpose of this specific application, most
of the class-A strain gauges are encapsulated gauges and possess both
temperature and creep compensation properties.
For a certain type of the class-A gauges, the gauge can
be manufactured with effective modulus compensation as well, and those
strain gauges are sometimes called EMC gauges.
The EMC gauges are manufactured from kamar foil (EKF-series),
and the application of EMC gauges is a solution for manufacturing low-cost
transducers because with EMC gauges one can eliminate the use of compensation
resistors and achieve a moderate accuracy for concerned transducers.
For more information on temperatrue compensation (S.T.C.),
creep compansation, and effective modulus conpensation (E.M.C.) of strain
gauges, please refer to the corresponding topic of STC,
Creep Compensation,
and EMC, respectively.
To choose a correct and proper
strain gauge, we suggest you first refer to
Strain Gauge Coding System,
in order for a quick understanding of BCM gauge features according
to its part number (P/N).
Listed in the following table is the class-A gauges available
in stock for quick delivery.
