Conversion of Strain Quantities (Voltage) Measured by Transducers into Proper Physical Quantities
Strain quantity (or voltage) measured by a transducer such as load cell or pressure transducer is converted into the physical quantity in proper engineering unit as follows.
The following 2 types of calibration coefficients are stated in KYOWA's Test Data Sheet. Use a proper one for the applied measuring instrument.
- A:Calibration coeffcient indicating the physical quantity corresponding to a reference equivalent strain of 1×10-6 strain
- B:Calibration coefficient indicating the physical quantity corresponding to an output voltage of 1μV against a bridge excitation voltage of 1 V.
When using a strain amplifier
Physical quantity = Measured strain (×10-6 strain) x A
When using an amplifier other than strain amplifier or recorder
