12 Load Cell Calibration Services PCB maintains a completely equipped calibration laboratory for calibration and re-certification of strain gage based torque sensors, single axis load cells, and multi-axis transducers. These services are available for sensors manufactured by PCB as well as other companies. Calibrations and re-certifications performed by PCB are traceable to the National Institute of Standards and Technology (NIST) and conform to ISO/IEC and ANSI/NCSL Z PCB s calibration laboratory is accredited by The American Association for Laboratory Accreditation (A2LA) to ISO The scope of our accreditation for load cells is: Range Best Uncertainty [1] (±) 10 to 500 lb (0 to 2225 N) 0.04% FS 100 to 10k lb (445 to 45k N) 0.06% FS 10k to 100k lb (45k to 445k N) 0.08% FS [1] Best Uncertainties represent expanded uncertainties expressed at approximately the 95% confidence level using a coverage factor k = 2. Basic Calibration Standard calibration services include five (5) points ascending and descending in tension and compression. Charted calibration data is provided in a theoretical vs. actual format with mv/v, non-linearity, and hysteresis provided at each increment. Shunt calibration data is also provided along with a precision shunt calibration resistor. The standard calibration service includes a basic certificate of NIST traceability.
