Strainsert Force Calibration Service

Strainsert’s calibration facilities enable Strainsert to certify all our manufactured products at our manufacturing site up to a 500,000 pound capacity. All Strainsert force measurements are traceable to the National Institute of Standards and Technology (NIST) and are performed by a highly-trained and experienced staff in a controlled environment. Strainsert calibration services include:

1. Factory-site Calibrations to 500,000-lbs.

   (Calibration capabilities to 4,000,000-lbs. are available in partnership with a local calibration facility)

2. NIST Traceability

3. Detailed Calibration Reports

4. Tension and/or Compression Calibrations

5. Compliance with ANSI/NCSL Z540-1 and MIL-STD-45662A Specifications (Optional)

6. Complete System Calibrations Available

7. Special Overload / Proof Load and Additional Testing

Standard Strainsert Calibrations:

All of Strainsert’s standard calibration procedures result in a customer report that includes the product model and serial number, rated capacity, test load(s) applied, output sensitivity recorded at each test load, and a statement certifying traceability of the measurements.

Stainsert offers several different calibration procedures and corresponding reports based on the customer’s requirements and product design criteria.

Available Standard Strainsert Calibration Procedures:

*: Indicates the standard calibration included in the purchase price.
**: System calibration is included when transducer and indicator/signal conditioner are purchased together as a system.

XX: Specify 2, 5, IN, or SC

CAL2: Calibration with respect to a straight line with a fixed endpoint. (Please see Cal2 Trimmed drawing below)

CAL5: Calibration with repect to the best straight line through zero. (Please see Cal5 Untrimmed drawing below)

CALIN: System calibration with an indicator readout.

CALSC: System calibration with an analog signal conditioner.

Cal2 Trimmed and Cal5 Untrimmed Load Cell Calibration

Proof Loading Calibration (PL):

A Proof Load Calibration reports the output at Full Load. Output data is reported in units of mv/V.

Loading Only Calibration (LO):

A Loading Only Calibration reports the output of the Force Sensor at each step of a 5 step calibration run. Force Loads are applied in 5 equal steps in ascending direction from (No-Load) to (Full-Load), then back to (No-Load) in one step. A total of three runs are reported.

The force sensor output is reported in mv/V. Calibration Analysis is based on percentage of Full Scale Signal, and provides:

1. Non-Linearity, Compared to Best Fitting or Predetermined Straight Line Signal
2. Repetition of Loading Cycles, Zero-Load, Max. Load readings.
3. Deviations of End Point , or Maximum Load, reading from Straight Line Signal.

For all functions, maximum deviation figures are reported, without averaging.

Strainsert Force Sensing Clevis Pins and Bolts are provided with a one direction (LO) calibration at no extra charge.

Loading and Unloading Calibration (LU):

A Loading and Unloading Calibration reports the output of the Force Sensor at each step of a 10 point calibration run. Force Loads are applied from No-Load to Full-Load in five equal steps, then back to No-Load in five equal steps. A total of three runs are reported.

The force sensor output is reported in mv/V. Calibration Analysis is based on percentage of Full Scale Signal, and provides:

1. Non-Linearity, Compared to Best Fitting or Predetermined Straight Line Signal
2. Repetition of Loading Cycles, Zero-Load, Max. Load readings.
3. Deviations of End Point , or Maximum Load, reading from Straight Line Signal.
4. Hysteresis

For all functions, maximum deviation figures are reported, without averaging.

Strainsert Flat Load Cells, Fatigue Rated Flat Load Cells, and Tension Links are provided with a one direction (LU) calibration at no extra charge.

Loading Only Calibration Dual Bridge (LOD):

Identical to the (LO) calibration for each indepedent bridge of a dual bridge transducer.

Strainsert Dual-Bridge Load Sensing Clevis Pins and Bolts are provided with one direction (LOD) calibration at no additional cost.

Loading and Unloading Calibration Dual Bridge (LUD):

Identical to the (LU) calibration for each independent bridge of a dual-bridge transducer.

Strainsert Dual-Bridge Flat Load Cells, Dual Bridge Fatigue Rated Flat Load Cells, Dual Bridge Tension Links are provided with one direction (LUD) calibrations at no additional cost.

Loading Only Calibration Bi-Directional (LOBD):

(LOBD) calibration loads are applied from (No-Load) to (Full-Load) in five equal steps, then back to (No-Load) in one step.

Two runs are recorded for each of the loading directions.

The transducer signal is reported in mV/V.

Calibration Analysis is based on %FS Signal, and provides:

1. Non-Linearity, Compared to Best Fitting or Predetermined Straight Line Signal
2. Repetition of Loading Cycles, Zero-Load, Max. Load readings.
3. Deviations of End Point , or Maximum Load, reading from Straight Line Signal.
4. Detailed Cross-Talk readings induced in the bridge circuit of the loaded direction.

For all functions the maximum deviation figures are reported without averaging.

Strainsert Bi-Directional Load Sensing Clevis Pins and Bolts are provided with one (LOBD) calibration for each primary loading direction at no additional cost. Cross-talk correction algorithms are also provided as required.

Loading and Unloading Calibration Bi-Directional (LUBD):

(LUBD) calibration loads are applied from (No-Load) to (Full-Load) in five equal steps, then back to (No-Load) in five equal steps. Two complete runs are made for each of the two loading directions.

The transducer signal is reported in mV/V.

Calibration Analysis is based on %FS Signal, and provides:

1. Non-Linearity, Compared to Best Fitting or Predetermined Straight Line Signal
2. Repetition of Loading Cycles, Zero-Load, Max. Load readings.
