Industrial temperature measurement | Basics and practice

Free Download From ABB

(Extract From the Introduction)

With this Handbook for industrial temperature measurements we are attempting to provide the technician with solutions to his wide variety of responsibilities. At the same time, it provides for those new to the field, insight into the basics of the most important measurement principles and their application limits in a clear and descriptive manner.

The basic themes include material science and measurement technology, applications, signal processing and fieldbus communication.

A practice oriented selection of appropriate temperature sensor designs for the process field is presented as well as therequired communication capability of the meter locations.

The factory at Alzenau, Germany, a part of ABB, is the Global Center of Competencefor Temperature, with numerous local experts on hand in the most important industrialsectors, is responsible for activities worldwide in this sector.

125 years of temperature measurement technology equates to experience and competence. At the same time, it forms an important basis for continued innovation.

In close cooperation with our customers and users, our application engineers create conceptsto meet the measurement requirements.

Our Sector-Teams support the customer, planner and user in the preparation of professional solutions.

Thermocouple App Notes Series, 1 of 4 – Thermocouple Fundamentals

App notes on how TCs work & their calibration

Thermocouple App notesOnline — Thermocouples are broadly used in many industrial and scientific applications. But it can be a bit tricky to understand how they work and how to calibrate them.

Fluke Calibration has developed a thermocouple application note series created by temperature calibration experts to help you learn what you need to know.

The series covers how thermocouples work, choosing calibration equipment, calculating uncertainties, and how to calibrate thermocouples.

There are four application notes in the series:

Air humidity and temperature play an important role in meteorology. Highly accurate measurements of these climate parameters form the basis of accurate forecasts and meaningful records.

The E+E Elektronik Model EE33 series humidity and temperature sensor is the only one on the market with a double-heated probe. Both the sensor tube and the sensor element are heated.

An application note, free for download from their website, tells the rest of the story.

Multiple Sensor Type Vendors

There are numerous distributors who sell many temperature sensor products and accessories, among other things. Some manufacturers specialize in producing a significant number (usually three or more) of different types of temperature sensors and sell to either a distributor network or directly to the public by Internet and/or Catalog sales (telephone or mail).

Start your search either here for vendors of multiple types or, if you are seeking a specific type, go to the vendor page index or directly to a page describing sensor types; you can find the vendors of specific types from many different places there.

TI Temperature Measurement Videos

TI, or Texas Instruments, is one of the world’s most prolific and largest makers of temperature sensors. They make all kinds but their sensors are mostly in the form of Integrated Circuit semiconductors.

TI also does an exceptional job in educating users how their devices work and how they can be interfaced and incorporated in measurement systems. Especially useful are the videos showing how some of their other integrated circuit modules can be used with external temperature sensors, like Thermocouples, RTDs and Thermistors.

Here’s an example of an interesting one:

Developed through TI’s expertise in MEMS technology, the TMP006 is the first of a new class of ultra-small, low power, and low cost passive infrared temperature sensors. It has 90% lower power consumption and is more than 95% smaller than existing solutions, making contactless temperature measurement possible in completely new markets and applications.

Check out their Video Channel on YouTube, especially the long list of videos already published about “Temperature Measurement”. It very straightforward; just go to:

Online Thermowell Calculation Tool

Emerson’s Online Calculation Tool Helps Users Select Thermowells in compliance with the 2010 ASME Standard

Emerson Video about PTC 19.3 TW Emerson Video about PTC 19.3 TW

MINNEAPOLIS MN, USA — Emerson Process Management has introduced an online thermowell calculation tool that incorporates therecent ASME PTC 19.3 TW standard.

“The new tool offers preliminary calculations and gives users the option to perform a quick pass or fail thermowell calculation,” said Danjin Zulic, temperature marketing engineer, Emerson Process Management. “Users can save time by performing iterative, preliminary calculations to select the right thermowell earlier in the design process.”

The tool is now available free-of-charge at Emerson is the first to make available an online tool offering a more automated approach to thermowell calculation as opposed to the traditional way of utilizing spreadsheets.

In addition to the tool, the web site has a link to an R21 Report request form for official evaluations.

“Once the thermowell order is ready to be placed, the official R21 report provides detailed documentation of the thermowell calculation,” Zulic said.

A video and white paper are also available on the web site that explain the new ASME PTC 19.3 TW standard.

Enhancements in the new standards and thermowell calculation tool include different types of stem profiles, more accurate natural frequency equations, and a calculated Strouhal number. The new standard also provides natural frequency correction factors that take into account different components of the thermowell such as the mounting style and temperature sensor mass.

To try Emerson’s thermowell calculation tool, learn about the ASME PTC 19.3 TW standard and read the white paper visit
