Rev. 2

1.0 SCOPE: This purchase description specifies a 2000 lbf Tensiometer Calibrator to be used for the calibration of cable tensiometers by selected Precision Measurement Equipment Laboratories (PMELs) .

2.0 PERFORMANCE REQUIREMENTS:

2.1 Measuring Range: The Tensiometer Calibrator shall have a measuring range of 10 to 2000 pounds.

2.2 Uncertainty: The Total Uncertainty of the Tensiometer Calibrator shall be within± 0.1 % of applied load over the entire measuring range.

2.2.1 Weight Calibration: The yoke and the weights supplied shall be calibrated with certification directly traceable to the National Institute of Standards and Technology (NIST) .

3.0 FUNCTIONAL REQUIREMENTS:

3.1 Weight Increments: The Calibrator shall be capable of applying any load from 10 to 2000 pounds in increments of 1 pound.

3.1.1 Weight Configuration: All weights shall be of nominal value following a 1-2-5 weight complement, adjusted to standard gravity.

3.2 Weight Location: All weights 10 pounds and greater shall be contained within the Calibrator' s frame. All weights less than 10 pounds may be hand weights and added to the yoke assembly by the Operator as needed. The hand weights shall be designed with a slot for easy placement on the yoke assembly.

3.3 Weight Loading: The weights contained within the Calibrator' s frame shall be able to be applied and removed without manual lifting by the Operator. Any combination of weights seleeted within the calibrator's frame shall be completely loaded or unloaded within one minute.

3.4 Loading: The rate of application shall be such that the "Shock Loads" do not exceed 2 inches per minute when the weights are applied or removed. The Operator shall be able to apply and remove the amount of weight selected using a switch or button.

3.5 Control Panel: Weights loaded on the Calibrator shall be operator selectable via a control panel located in front of the calibrator and no higher than 6 feet from where the operator is standing to the top of the control panel.

3.6 Load Rotation Limiter: The Calibrator shall have a mechanism which steadies the load, and limits the rotation of the applied load while it ' s hanging in place. This Load Rotation Limiter shall not affect the applied weight when the Calibrator is in use.

4.0 MECHANICAL & PHYSICAL REQUIREMENTS:
