3-A and BPE - BE in conversation?

Posted on January 16, 2008

ASME-BPE (BioProcess Equipment) committees meet Jan. 21 - 24 in beautiful San Juan, Puerto Rico.


The 3A organization, known as 3-A Sanitary Standards Inc., meets in May of each year.


These organizations are quite different, yet use much the same language to describe their objectives.


The question is:


What relationship between the organizations would best serve the industries?


It seems that both organizations are concerned about providing guidelines in the areas of sterility, sanitary, clean-ability, hygienic equipment, product safety and cross-product burden.   A review of the topics of interest from the 3A , 2007 Annul Meeting, indicates a few examples of the language and topics that are of interest to both BPE and 3A.


3A includes pharmaceutical products in the  3A mission statement and BPE addresses personal care products within it's mission, indicating broad and holistic areas of concern.


Burns Engineering designs Sanitary products to meet the guidelines of both organizations.  The Burns' Sanitary RTDs are designed to meet the 3A-74 specification for use in the Food and Beverage industry for milk and dairy processes.  The Sanitary products also incorporate the materials, surface finishes, sanitary flange designs as guided by the BPE-2005 standard.  The Burns Engineering Sanitary Wells  and Non-Intrusive RTDs, incorporate the same design criteria for use in both industries as well as the CIP and SIP processes, insuring a drainable design and NO flow restrictions.


The design expectations are similar and in many ways overlapping, such that the Burns' Sanitary RTDs are applicable across the industries of Biopharma, Food and Beverage, and Semiconductor.


If the product design is able to cross industries, can the conversation cross industries?


What do you think?  Should there be closer collaboration?

Brilliance at ASTM Committee E20

Posted on December 27, 2007

John Zwak, Sr. Metrology Engineer and Jim Burns, President participated in the ASTM Committee sessions in November.  John is the Secretary for Committee E20 on Temperature Measurement, and Jim is the Chairman for Subcommittee E20.04.01 on Thermocouple testing where John is also the Secretary.


This is not only an opportunity to bring Burns' 47 years of experience to the conversation but to learn a lot from the many other brilliant folks in attendance.


Speaking of brilliant!  As part of the E20 meeting, Greg Strouse from NIST offered a presentation on an amazing technology as a potential replacement for a Standard Platinum Resistance Thermometer, SPRT.


The technology, "Sapphire Whispering Gallery", has been around for years.  Classic applications leverage the phenomenon of total internal reflection of energy waves, for the development of Oscillators to meet the demands for precision signal generation and processing.    In these applications, the device is generally temperature compensated to reduce temp effects.  This Review of SWG-mode Oscillators  gives a pretty technical, but interesting overview of the technology.


Mr. Strouse and his friends at NIST are exploring a concept that leverages the predictable temperature sensitivity of the Sapphire Whispering Gallery Thermometer, (SWGT) to accurately measure temperature with uncertainties of < 10mK.


Awesome stuff!  We here at Burns will be watch how this technology develops.   Check back with us to see what additional insights are revealed by the great work at NIST.


Post a comment!  I'd love to hear your thoughts on this interesting SWGT idea.

Committed to your success! MWFPA 2007

Posted on November 21, 2007



I am sitting at the MWFPA 2007 event listening to Vince Lombardi, Jr. speaking about Teamwork!  A topic that transcends industries, businesses, projects and issues.


It got me thinking....


That is the key to what Burns wants to BE;  A team, with you.  To BE in a Teamwork relationship about the temperature related challenges that you have on your list of concerns.  To bridge our Temperature expertise and your process expertise to achieve the goal which can be best described as your success.


For a guy from Minnesota who happens to be a Minnesota Viking fan, I am humbled by the powerful message, in the presence of the son of Coach, Vince Lombardi.


His message:  "combining clear goals and dreams, with commitment and mental toughness, will enable success", is exciting and energizing.


Burns will BE committed and BE temperature experts on your team.


We would love to hear from you about how we can team-up for your success.

Thinking about MWFPA.

Posted on November 21, 2007

How important is the requirement for No-Animal-Derived materials?


3A vs. the ASME-BPE? What’s your perspective?


Is irradiation effective as a method to insure safety?


International expansion: Your thoughts on maintaining food safety?


The role of temperature control on your CIP/SIP efforts?


Would better temperature-control improve your efficiency?


MWFPAWow. Lots of questions on our minds as we head to Milwaukee next week to participate in MWFPA 2007. The food & beverage manufacturing process is a challenging one. We've learned that by being trusted partners for clients in the food & beverage industry for more than 45 years. So we hope to see some old friends and meet some new ones next week.


But why wait? Let's start the conversation right here: What are the most pressing issues you face in the food & beverage manufacturing process?


Bet we've got a few ideas of how temperature measurement can help!

Vacuum, Pressure, Steam… No Problem!

Posted on November 21, 2007

A harsh environment and a tough packaging challenge in the BioPharma and Food & Beverage industries, pretty much sums up the development task for our newest Autoclave Load Cell product: Burns Model 21090.


As you may know, the operating conditions of the autoclave process ranges from vacuum to positive pressure steam at temperatures up to 135C. Individually, these conditions are fairly easy to design around, but the combination presents a few interesting challenges in the RTD world – and sealing the device such that the insulation resistance performance is maintained after multiple cycles is the fun part.


Other features we designed into our new autoclave sensor include a .125 diameter stainless steel sharp-tipped sensor sheath to facilitate insertion through the rubber membrane of the load cell, and a dual Pt100 element that can support either a 3- or 4-wire operating connection. The cable features a silicone rubber jacket providing the durability necessary to meet the handling concerns that were shared with us from users of large chamber autoclave systems. We also designed a bulkhead/transition system to assist in providing a sealed penetration through the wall of the autoclave.


Now back to the sealing challenge!


Inside the transition housing (or handle which is laser marked for easy identification) is an elegant design which protects the 8-wire joints, simply yet effectively seals the sensor and involves very few complex parts. The design insures ease of manufacture and an epoxy fill method that results in an extremely stable final assembly.


New Autoclave Sensor


We're proud of the creativity of the approach and through our design verification testing, we're confident in the high reliability of the Model 21090 in the harsh environment of the Autoclave processing cycle.


Got another challenging application?  Comment on the blog or give us a call.

"There's an obstruction in the way of getting the sensor in the location....  Help!"


That's what our customer told us. So we took on this Sanitary temperature application challenge and had fun looking for creative solutions. In this case, the sensor needed to be broken in order to fit into the measurement location. This was the perfect application for a segmented sensor. For more information, see the Application Notes, "Sanitary RTD Probe for Tight Locations" on our Burns' site.


Challenging is the new exciting!

A Man and an RTD with a Mission.

Posted on November 21, 2007

Serial #16 Serial # 16 was destined for a higher purpose. Measuring temperature was its original calling, yet when Dad (Don Burns) retired 10 years ago and transitioned the company to my brother JD and I, we honored Dad's legacy and serial #16 received a promotion. This RTD, manufactured in August of 1962 became a symbol of longevity, creativity and honor. Appropriately mounted and framed, we presented this original device to Dad in recognition of his retirement as well as his technical brilliance and passion for creative problem solving.


Many more serial numbers have followed in the cure cycles and calibration schedules of serial #16, all of which were destined for their own greatness and purpose in various industrial processes and pharmaceutical applications. Number 16 may never experience the energizing environment of a refinery or participate in the creation of a life-saving drug, yet #16 holds an honorable place in the hearts of all who have a passion for solving temperature measurement challenges.


I often bump into friends of dad’s from the early days of #16. It's always fun to hear their stories and see the passion in their eyes. (Share yours on the BEblog if you have one!)


Congratulations Dad and Thank You serial number 16.

ASME-BPE: A Commitment to Life.

Posted on November 21, 2007

ASME-BPE.....  What an amazing group of passionate folks working together through a series of sub committees and task groups to improve the world of BioProcess Equipment. I visited several of the working committees during October in Philly. I was impressed how diligent the groups were about being precise as well as how attentive everyone was to current practices in the industry. As much as the Subcommittees strive to give guidance, they also realize they serve the industry, and they live in the industry. I observed a careful balance of definition and openness; guide but don't handcuff; lead but don't leave behind. The collaboration was beautiful.


It appears this group really wants to influence life in the future. The article from Mechanical Engineering, December 2005, Getting a New Life gives an interesting perspective on that commitment, on an international scale.


They are working hard to complete the 2007 version of the BPE Standard, targetting an early 2008 release.


How have you seen the  ASME-BPE organization help your organization?  I'd love to hear your thoughts.
