Strain Indicator Calibrator Vishay Model 1550A


Strain Indicator Calibrator, Vishay, Model 1550A, Strain, Indicator, CalibratorStrain Indicator Calibrator Vishay Model 1550A is atrue Wheatstone-bridge simulator, the 1550A Strain Indicator Calibrator presents known and repeatable resistance changes to the input of the indicator. Three decades of push buttons are used to produce incremental resistance changes. The 1550A is NIST-traceable.

Strain Indicator Calibrator Vishay Model 1550A is a laboratory standard for verifying the calibration of strain and transducer indicators.
