Calibration Test Services and Equipment
Dynamic Strain, Force, and Strain gage Torque & Load Calibrations
PCB
® offers calibration services for dynamic strain and force sensors, as well as strain gage torque sensors and load cells. Each dynamicstrain or force sensor is provided with a five-point ascending compression calibration. Sensitivity and non-linearity data are reported.Tension calibration may be supplied upon request. Strain gage torque sensors are calibrated in both clockwise and counterclockwisedirections. Strain gage load cells are calibrated in both tension and compression. Sensitivity, non-linearity, hysteresis, and shunt calibrationdata are provided for static sensors.
Dynamic Strain Sensor Calibration Services
â– Strain gage reference
â– For Series 240 and 740 ICP
® strain sensors
Dynamic Strain Sensitivity Calibrations
A known strain input is placed on the sensor, and sensitivity measured via reference sensor
Dynamic Force Sensor Calibration Services
â– Strain Gage Reference
â– 10 to 100k lb (445 to 450k N range)
Comparison Calibration
â– 1.0 % FS accuracy A large,
hydraulic press manufacturer generates compressive loads for reference comparative testing
Torque Sensor Absolute Calibration
â– Torque arm method, where known weights are applied from a beam at known distances from the sensor's axis of symmetry
Torque Sensor Absolute Calibration
Otherwise know as a “torque arm”, known weights are suspended from the beam at known distances from the sensor’s axis of symmetry
â– 10 to 25k in-lb (1.10 to 2800 N-m) range 0.04% FS accuracy
â– 25k to 100k in-lb (11,300 to 56,500 N-m) range 0.14% FS accuracy
