#1 Reason Why Force Measurements Matter - Force Transducer Testing and NASCAR

Why Force Measurements Matter - Force Transducer Testing and NASCAR Why Force Measurements Matter - Photo Courtesy of Associated Press Austin Dillon went cascading into the catch fence at Daytona speedway on the early morning of July 6th, 2015. Was he thinking of all the testing his NASCAR Sprint Cup car goes through? Absolutely not! […]

Force Measurement Error - Thread Loading In Compression

Force Measurement Error - Thread Loading In Compression It is important to remember that not all calibration laboratories provide the same type of calibration service.  For load cells calibrated in compression, there may be a noticeable difference in output.  The output is dependent on the calibration fixtures used at the time of calibration, the alignment […]

ASTM E74 Primary, Secondary and Working Standards Explained

Primary Force Standards (As Defined per ASTM E74) Morehouse Deadweight Machine ASTM E74 Standard Practice of Calibration of Force-Measuring Instruments for Verifying the Force Indication of Testing Machines (section 3.1.2) defines a primary force standard as a deadweight force applied directly without intervening mechanisms such as levers, hydraulic multipliers, or the like, whose mass has […]

Tips from the Cal Lab – Point of Use to Save Time

Morehouse 10 MN UCM Have you ever noticed a technician running around your facility asking, “Does anyone have a 5/32-inch Allen wrench?” Well, if you are reading this and you are not in the United States, Liberia, or Burma, the 5/32-inch may not make much sense. Didn’t the US Government pass something in 1988? Oh […]

Single Measurement Bliss

Morehouse is proud to present Single Measurement Bliss! by Dilip Shah When you make the first measurement, everything looks fine. It is when you make a second, repeated measurement and it is different from the first measurement that doubt begins to arise. Which one is the correct measurement? Then, you take a third measurement, and […]

Unbolting Load Cells May not Produce Repeatable Calibration Results

Unbolting Load Cells May not Produce Repeatable Calibration Results Unbolting Load Cells might be common practice, though the errors associated with this practice can be quite high. This article discusses ways to minimize these errors. Bolting a Load Cell Thread Class and Torque Applied • Morehouse recommends bolting a load cell to a base before sending […]

How to Convert Weights to be used as Force Standards from Mass and Force Transducers to Mass

The mass of a body relates to the amount of material it contains. Forces are defined by Newton's second law of motion as expressed in the equation: F = kma Since it is impractical to make an accurate determination of force directly from this equation - at least as a routine procedure - it is customary to […]
