How automated calibration can help service companies be more competitive

Service companies that perform calibrations for the process industries operate in a challenging environment. Not only is there a lot of competition, but contracts for customers are based on estimates, meaning that every additional hour of work directly affects the bottom line. Finding and retaining skilled calibration technicians is also a challenge. So, what can service companies do to make their quotations more accurate and ensure work is carried out as consistently and efficiently as possible? The answer is to…

IR Inspection Windows – See What You’ve Been Missing

An Infrared Inspection Window is a window that is used to separate environments of differing pressures or temperatures while allowing light energy at a specified electromagnetic wavelength to pass between the two environments. Source: IR/INFO.ORG…

“How Accurate Are Your Temperature Measurements?”

In a recent issue of “The Monitor” Windmill Software discussed this important factor that everyone considering the use of thermocouple temperature sensors should know The full article is online at: https://www.windmill.co.uk/thermocouple-accuracy.html “There are many factors that limit the accuracy of…

Understanding Pressure Calibrator Accuracy Specifications

  Comparing the accuracy specifications of pressure calibrators can be a challenging task because different manufacturers specify accuracy in different ways. This means that you can’t simply compare the numbers given in the specification – you need to understand how these numbers are calculated and what they mean in practice. In this blog post, I look at the different ways pressure calibrator accuracy specifications are presented, explain what they mean, and compare them, as well as take a brief look…

The irony of the magnet system for Kibble balances—a review

The magnet system is an essential component of the Kibble balance, a device that is used to realize the unit of mass. It is the source of the magnetic flux, and its importance is captured in the geometric factor Bl . Ironically, the Bl factor cancels out and does not appear in the final Kibble equation. Nevertheless, care must be taken to design and build the magnet system because the cancellation is perfect only if the Bl is the same in…

Achievement of 0.005% combined transfer uncertainties in the NIST detector calibration facility

Improvements in a lamp-monochromator-based facility at the National Institute of Standards and Technology (NIST), the Visible near-infrared Spectral Comparator Facility (VisSCF) which is used to calibrate optical detectors for spectral radiant power responsivity from 300 nm to 1100 nm, are described. These changes include extending the VisSCF operational range down to 300 nm from 350 nm, thereby fully covering the ultraviolet-A (UVA) spectral region and partially covering the UVB range. These improvements have lowered the magnitudes of most of the components in the uncertainty budget…

Spectral irradiance scale realization and uncertainty analysis based on a 14 mm diameter WC–C fixed point blackbody from 250 nm to 2500 nm

Spectral irradiance scale in the wavelength range from 250 nm to 2500 nm was realized at National Institute of Metrology on the basis of a large area tungsten carbide–carbon (WC–C) high temperature fixed point blackbody, which is composed of a 14 mm diameter WC–C fixed point cell and a variable temperature blackbody BB3500MP as a furnace. A series of 1000 W FEL tungsten halogen lamps were used as transfer standards. The new spectral irradiance scale was compared with the scale based on a variable-temperature blackbody…

Infraspection Institute Announces Release of Updated Standards for 2022

Burlington, NJ March 1, 2022 – Infraspection Institute has announced the release of updated versions of its popular series of Standards for infrared thermography. All twelve Standards have been revised to keep abreast of technological and industry changes. Source: Infraspection Institute News…

How to avoid safety and compliance issues in fine chemicals

Safety and compliance are non-negotiable in the fine chemicals industry, which produces complex, pure chemical substances such as active pharmaceutical ingredients. Fine chemicals are batch driven, with complicated, multistage processes where accuracy and efficiency are critical. In this industry, one of the keys to ensuring both safety and compliance is that measurements taken throughout the production process are accurate, which can be challenging to say the least with paper-based calibration. Paper-based calibration is time consuming and because it relies on…
