BCM Class-A Strain Gauges
for Transducer Applications
BCM class-A strain gauges are specially developed for manufacturing 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 temperature compensation (S.T.C.), creep compensation, and effective modulus compensation
(E.M.C) of strain gauges, please refer to the corresponding topic of STC, Creep Compensation, and EMC, respectively.
Listed in the following table is the class-A gauges available in stock for quick delivery.
