Autoclave Temperature Measurement

Posted on July 29, 2013


The Autoclave processing environment can present an interesting set of challenges.

  • Is the drain measurement representative of the load?
  • Is the load uniformly heated?
  • How many wall penetrations are required to insure proper processing?
  • Large chambers required to sanitize large items create sensor cables routed in may places.

From Autoclave as small as those used in a dental office or hospital, to systems large enough to laminate airplane wings, the challenges present themselves in many ways.  The team at Burns have frequent conversations about the issues as they related to the measurement need with multiple autoclave users.


See earlier post about the Autoclave load measurement challenges.


Each of these systems present unique challenges including access into the chamber, confined or complex maintenance access, and measurement at the point of highest interest; on the actual item(s) being processed.


We have responded to these concerns with several products designed for this exact environment.  The SA series of Autoclave instruments are water tight, durable and built for the demands of multiple Autoclave systems.  See the entire Autoclave family.

RTD Performance - Periodic Verification?

Posted on November 14, 2012

YES!   It can be as easy as measuring the resistance in a container of ice water. (you don't need a Triple Point of Water Cell.)ice-bath-a.JPG We have discovered too many times that sensors are installed in systems that experience a combination of temperature cycling, over temp excursions, vibration, high flow rates and /or just left unattended for years.  In many cases this is not a concern based on the requirements of the measurement.  Although, if these influences exists and the expectation is to be confident that the measurement represents the actual process media temperature, periodic verification can ensure that confidence. tech-papers.jpg This paper titled:  Developing a Periodic Performance Verification Program  for Platinum Resistance Thermometers, will help you understand the importance, and provide some guidance on how to establish a verification approach that is right for your application. Visit the Burns Website Technical Papers page - register/sign-in to access ALL the papers.  This set of papers provides an in-depth study of the source of error,  the cost of measurement error, and how to manage the multiple influences on the measurement. Our Mission is Your Measurement! We believe that any sensor will provide a measurement, although if the influences that exist in the application are not managed or planned for, that measurement may not represent the actual process temperature. If you would like to discuss your application to ensure measurement confidence in your operation - call or send a note.  Here is our contact information.

Mercury in Glass - a thing of the past.

Posted on February 16, 2011

nist.jpgRead this important message from NIST:


No more Calibration of Mercury Thermometers (MiG).


 In the big picture, this is necessary to help build momentum to STOP the use of these devices.  There are a lot of reasons they are in place, but the Mercury risk to the environment is too great.


FYI - Burns can help provide an RTD based instrument to replace the MiG.

Always Curious - Temperature in Industry!

Posted on January 13, 2010

How deep does the interest in temperature measurement in the industry run at Burns Engineering?  So deep that Jan, Burns' Customer Service Representative, went on a tour of a Power Plant with her family.  Here is what she observed at the Coal Fired Power Plant.


I recently had a chance to tour a power plant and observe how coal is converted into energy to heat our homes, businesses etc.coal-electric-plant-2.png  To me the most interesting part of my tour was watching the coal cars being emptied.  The trains come in from Wyoming or Montana with 105 to 117 cars loaded with coal. Each car holds up to 120 tons. The cars are automatically pulled thru the plant and each car is completely turned over and emptied onto a conveyer where the coal is crushed to fine dust for burning. The long line of cars continue to move slowly thru the plant and each one is emptied one after the other.  As the coal is crushed, water is continuously sprayed over it to keep it compacted.  The plant burns coal at a rate of 30,000 tons every day; about 3 trainloads, or about 9 million tons a year. 


I was able to stand on the roof and look over the 4500 acres the plant is on.electric-plant-3.png   There is a 88 acre coal storage pile with a 40 to 45 day supply of crushed coal piled high for burning.  I saw the main control room, the boilers and the large equipment used to move piles of coal out in the yard.  There are 3 boilers, each more than 200 feet tall, that use about 3,335,000 gallons of water an hour to produce steam.  All 3 boilers combined,  burn more than 1300 tons of coal per hour.   This is quite an engineering marvel and if you ever get a chance to go thru a power plant I highly recommend.


Jan,  Burns Customer Service.

Thanks for sharing your story Jan!

Trade Show? No Go?

Posted on December 18, 2009

What is your opinon of the classic Trade Show experience?  Burns participates in various Trade Shows and although there are always some interesting people to meet and facinating things to see, the attendance has been pretty thin.iphex-1.JPGmwfpa-traffic2.JPG


Has the Trade Show style event run out of steam?


Has information accessibility via the WEB transcended the historical value of the Trade Show hands-on experience?


What do you think?


What approaches do you prefer to evaluate products and services and see what's new?

Air Temperature & only the Air Temperature

Posted on August 28, 2008

The Engineering team at Burns has for many years enjoyed the air temperature measurement challenges in clean rooms, HVAC, storage areas, transportation, compressor rooms, production areas, environmental chambers, critical office areas..... 


In some instances it's all about durability and accuracy.


In other cases the challenge is measuring the temperature of the  AIR and not the WALL or some other influence within the wall.



Burns brings to these applications;  a myriad of design styles and adaptations, the wisdom that can be found in the series of technical papers on PRT Sources of Error and a passion for creative problem solving.


Share with us your Air temperature measurement challenge and we'll get the team engaged in making you a hero!  Call us at 952-935-4400, email us at or comment here on the BEblog.


We are ready to discover, design and create something to insure your success.  That's just the stuff we like to do....

RTDs in small packages…

Posted on July 11, 2008

The best things come in small packages.  I've heard that phrase many times.  Recently the engineering team at Burns has been working on a stealth project to evaluate material and process approaches for the purpose of; mini, tiny, micro and just little RTD's.  We code named the project SLIM and gave it a mascot....slim.jpg




We discovered some interesting materials and process options, and broke a few assumptions and perceived constraints.  Then, in the design mode, applied these ideas and created a few new RTD's for various applications throughout the BioPharma, Food & Beverage, PetroChem and Ethanol industries.  These little RTD's play a role in Bearing temperature monitoring, product transit condition monitoring and various surface sensing and tight locations where addition temperature profile and awareness is important to the process.




The team had a blast think beyond the rules, historical approaches and known materials.  In true "achieve, change and improve" mode, we are doing it again.


What paradigms have you busted through recently?  Click the comment button and tell us a bit about your recent  A-ha's.

More than a FEW at the FEW Expo

Posted on June 17, 2008

Ethanol and it's expansive support industry at the FEW Event have rushed the gates at the Gaylord Opryland Resort and Convention Center.   They are talking everything from filter bag systems, mixers, bacteria issues, biodiesel, fermentation and thermal oxidizers....   The conversation even dipped into the area of CIP (Clean in Place), posing the question, "Should the Ethanol fermentation process move toward the sanitary guidelines similar to the food and beverage industry?"  This was driven by the co-product "Distillers Grain" entering into the food stream through the animal feed.


The Expo opened Monday evening, breaking the ice with a Grand Opening and massive social in the expo arena.  The spirit in the room was an interesting mix of excitement, passion and commitment to all the good aspects and value of Ethanol as a clean and renewable fuel energy source.  That doesn't mean that there aren't questions and concerns about the interdependency with the other uses of corn, and the economic complexities as the ethanol industry grows....  It sounds like these folks are aware of all of this, and are committed to being good stewards of the resources they consume and at the same time looking for additional Sugar & starch sources to balance the demand for corn.  One alternate fermentation product being discussed is ALGAE!  Now that's being creative!


More later from on the Fuel Ethanol Workshop & Expo and the passionate folks in attendance.

Burns PRT goes swimming…

Posted on April 21, 2008

Originally design in 1975, the Burns Engineering Underwater PRT has found itself serving many submerged needs in industries from Power generation to Paper processing; helping to protect the delicate aquatic environment.




In Minnesota it's all about the Walleye...


The Burns Underwater PRT spends so much time underwater it's beginning to grow gills


In my search, DNR within every state in the US has regulation and guidelines for Industrial water discharge temperature to insure protection of the lakes, rivers and streams.




We all have a responsibility to care for our world.  This is one way Burns Engineering supports a Greener Globe!


What can we do to help you protect the environment?

Bearing Down on Bearing Temperature

Posted on February 13, 2008

In a past life (ok, "job position") I was responsible for a large wind-tunnel facility that included two 150 hp motors and multiple shaft bearings. To complicate the maintenance issues, the motors drove large fans that pushed air heated to 400°F, so the stress and temperature of the bearings were a significant concern.


I wasn't the only one with this concern.


machinerylubelogo.pngHere is an interesting article:  Eugene Matzan, "Detecting Premature Bearing Failure". Machinery Lubrication Magazine. May 2007. This is a good overview of the importance of monitoring bearing health.


mrotodaylogo.pngIn the article  "Bearing it all" provided by:  Power Transmission Distributors Association, June/July 2004 issue of MRO Today magazine. Copyright 2004, They deal with the "Too Hot To Touch" question and put the temperature in perspective.


mvclogo2.pngJust to give an international flavor, Machinery Vibration Consultants, Ltd from England, present an article titled:   "PREVENTING THRUST BEARING FAILURES", copyright 2006. Again, the discussion here is about temperature monitoring to prevent failures...


Burns Engineering's family of bearing temperature monitoring sensors provide an effective method of Bearing health monitoring. They can be customized to meet a variety of installation approaches and carry the Burns quality you can depend on.


Have a bearing health-monitoring story to share? Click the comment button above and share it! It's been a few years (ok, several years) since my days at the wind-tunnel facility, so I could sure benefit from an update about bearing maintenance issues!
