ISA Webinar Recording: Temperature Measurement and Control

By Greg McMillan 1 Hour & 35 Minutes+

 

This educational ISA webinar on control valves was presented by Greg McMillan in conjunction with the ISA Mentor Program.

Greg is an industry consultant, author of numerous process control books, 2010 ISA Life Achievement Award recipient and retired Senior Fellow from Solutia Inc. (now Eastman Chemical).

The ISA Mentor Program enables young professionals to access the wisdom and expertise of seasoned ISA members, and offers veteran ISA professionals the chance to share their wisdom and make a difference in someone’s career.

Temperature Measurement with your Computer

Windmill LogoOne of the best of our favorite resources on the Web is a software company on Manchester, England, Windmill Software. They have supplied free PC software for Test & Measurement to all who wish to download it from their website: http://www.windmill.co.uk,

Windmill has for many years also published a free monthly informative eNewsletter called Monitor newsletter (ISSN 1472-0221); archive and subscription available online at http://www.windmill.co.uk/newsletter.html.

At last look it was up to issue No, 224!

Here’s links to one of the extra specials they have done on the subject of temperature measurement

(Excerpt)

Measuring Temperature with a Computer

Temperature measurement is the most common application of data acquisition systems. You will need a device to measure the temperature – a temperature sensor. Thermocouples, resistance temperature devices (RTDs), thermistors, platinum resistance thermometers and infrared thermometers are all types of temperature sensor.

The most popular are thermocouples and RTDs. The sensors you choose depends on several things, such as as your expected maximum and minimum temperatures, cost, accuracy needed and your environmental conditions.

To get data from the temperature sensor into your PC you need a data acquisition interface with suitable software. The interface unit plugs into your computer, for example into the USB or Ethernet port.

You wire the sensor to the interface, install the software and the computer can now monitor temperatures.

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.
