Dead Weight
Force and Load Cell
Calibrating Machines |
The Ultimate calibration Standard |
Description
Of all the devices and machines designed to measure mechanical forces none has ever equaled the positive and
unfailing accuracy obtainable with dead weights.
Morehouse has two different models of Dead Weight Load Cell Calibrators available: The Model L and the
Model MH.
The Model L is available only in capacities of 1,000 lbf or less – standard capacities being 500 lbf and 1,000 lbf,
or the approximate equivalent in kilograms or Newtons: 250 and 500 kgf respectively, or 2,500 and 5,000
Newtons respectively.
The Model MH is available in larger capacities – standard capacities being 2,000 lbf, 5,000 lbf, 10,000 to 100,000 lbf, or the approximate equivalent in kilograms or Newtons.
Construction
Both models of the machine are designed to make full use of the accuracy of dead weights without any
mechanical interference or machine losses. The yoke assembly on which the dead weights are suspended bears
directly on the instrument being calibrated.
There are no intervening levers or flexures between the weight
complements of the machine and the instrument being calibrated to introduce ratio and beam deflection errors.
The loading stages on both models are adjustable to accept instruments of varying heights and to allow for
tension as well as compression calibrations.
The weights supplied with both machines are machined from stainless steel and are adjusted to better than
.003% of their nominal weight. The accuracy of the weights can be certified traceable to the National Institute of
Standards and Technology.
