What is measurement risk?

April 12, 2017

Measurement decision risk as probability that an incorrect decision will result from a measurement. Are you telling your customers instrument passes without considering measurement uncertainty? If taken to court, are your measurement defensible? This paper examines the proper way to make statements of compliance.

Uncertainty propagation for force calibration systems, or how to put together a force CMC.

February 07, 2017

Having troubles understanding measurement uncertainty and how to put together a budget? This paper examines all of the components required to put together a full calibration and measurement capability (CMC) reviewed by Accreditation Bodies for your scope. This is a guide to calculating force measurement uncertainties and was published in Cal Lab magazine.

The Design, Development and Commissioning of a 2kNm Torque Standard Machine

January 02, 2017

This paper describes NPL’s 2 kN·m torque machine — Now at Morehouse Instrument Company — a lever deadweight machine with a vertical torque axis and an uncertainty of ±0.002 %. Despite the greater difficulty in applying torques to a vertically mounted transducer, this design was selected as it enables a symmetric “pure” torque to be applied. In addition, this design provides adaptability, enabling comparisons with the application of asymmetric torque and “on-thefly” torque calibrations to be studied.

How to make your load cells perform better - The advantages of Installing an integral threaded adapter

May 10, 2017 12:00:00

There are three distinct advantages to installing a threaded adapter on a shear web load cell. There are also three disadvantages of not installing a threaded adapter that will sacrifice performance, repeatability, and reproducibility of the load cell.

The Importance of Torque Control

March 13, 2017 12:00:00

What happens when torque is not applied properly. Do you even know if your wrenches are capable of applying the correct torque? This blog explains over and under torquing as well as something called back torquing. Back torquing is when you have no idea that a particular wrench is applying a torque in the opposite direction, resulting in inaccurate torque values being applied to the fastener.

Load Cell Creep

March 07, 2017 12:00:00

Load Cell Creep is the change in load cell signal occurring with time while under load. This post discusses the three common load cell creep definitions with some humor. Morehouse sell good load cells that have very low creep.

Measurement Risk - What you need to know about your calibration provider. You may not be getting what you really need!

January 31, 2017 12:00:00

Have you ever heard the term measurement risk? It is a real term that may make the difference from a $ 500 loss to hundreds of thousands, or hundreds of millions in losses. When things work, no one really thinks about risk, when they do not, everyone is to blame. This article examines what measurement risk is and why you should care about it.

Does resolution need be in an uncertainty budget?

January 24, 2017 12:00:00

There’s a question I’ve heard asked more often than it should be: "How should I treat measurement uncertainty contributed by the resolution of a device?"
