### Torque Formulas and Conversions

Torque Explained In the simplest sense Torque = Force * Length Torque is derived and traceable to SI units of length,  mass,  and time. The meter is the length of the path traveled by light in vacuum during a time interval of 1/299 792 458 of a second. The kilogram is the unit of mass; it is equal […]

### ASTM E74 Calibration Procedure Simplified

Steps recommended to perform calibration in accordance with ASTM E74-13a. Stabilization Allow UUT to come to room temperature Warm up Instrumentation Preparation Select 10-11 Test points IF UUT IS TO BE USED IN BOTH INCREASING AND DECREASING FORCES,  THE DEVICE MUSE BE CALIBRATED IN BOTH MODES.  THE SELECTION OF FORCE POINTS SHOULD BE AT LEAST […]

### Keep your force measurement system in control with Statistical Process Controls (SPC) and 5 in 1 solution

In previous posts, we have been focusing on measurement errors.  Good measurement practices are equally important.  We often forget about those practices we put in place to make sure our equipment is working properly.  Monitoring your process by putting practices in place to ensure that your measurements are accurate is essential to limiting your risk and keeping […]

### Good Force Measurement Practice - Stop using 4-wire systems and switch to 6-wire systems

The majority of force or torque systems we calibrate each year consist of load or torque cells, an indicator or readout, cables, adapters and some sort of shipping or carrying case. Around 90 % of these systems come in with an indicator only capable of supplying an excitation to the bridge and measuring a signal […]

### The Measurement Risk Lottery

no one won this drawing and the lottery is now up to over \$1,300,000,000.00! The Powerball is up to over  \$1,300,000,000.  A number so large, it cannot even be displayed on the lottery billboards.  How does a jackpot get this high? The odds of winning a prize are 1 in 24.87. Roughly a 4% chance. […]

The purpose of this blog is to discuss the common types of load cells used in general force measurements.  We will discuss the advantages and disadvantages of each type of cell. These load cells consist of the following: Column Load Cells Multi Column Load Cells S-beam Button or Pancake Shear Web Single Column or High […]

### Calibration and Measurement Capability (CMC) Workbook For Force - ASTM E74 Uncertainty

Morehouse has developed an excel workbook to help those trying to figure out measurement uncertainty and how to calculate their Calibration and Measurement Capability (CMC). Updated 9/05/2020!  The new update contains coefficients for interpolating uncertainty. Most of this workbook is set up for labs following the ASTM E74 standard.  (With slight modification the uncertainty sheet […]

### Morehouse 7 Step Process For Troubleshooting A Load Cell

Visual Inspection Lets Us Know Which Cell Is Damaged We have wasted countless hours trying to troubleshoot nonworking load cells.   In an effort to provide better customer service and shorten our calibration lead time (most calibrations are performed in 5-7 business days) we have developed a process to troubleshoot nonworking load cells.    This […]

### Measurement Uncertainty Calculations and how the Measurement Hierarchy works in relation to measurement uncertainty

Metrological Traceability:  Property of a measurement result whereby the result can be related to a reference through a  documented unbroken chain of calibrations, each contributing to the measurement uncertainty.  This article will define each level of the measurement hierarchy as it related to measurement uncertainty for force measuring devices and then compare the expanded uncertainty […]
