CE Authorized for use in the EU - Series A

Posted on September 11, 2013

a01.jpgThe Burns Engineering Series A RTDs have been self certified as complying with the European Parliament Directive 2011/65/EU on the restriction of the use of certain hazardous substances in electrical and electronic equipment (RoHS).  Consequently the CE mark has been applied to the Burns Engineering Series A product for compliance to directive 2011/65/EU.  No other "New Approach" directives were found to apply.

 

The Series A products have been self certified for European Parliament Directive 2001/95/EC on General Product Safety.

 

The CE mark applies to All the Series A models

 

See the Series A catalog for product details. http://www.burnsengineering.com/local/uploads/content/files/series_a.pdf

 

See the Series A Instruction Manual.

Measuring the Actual Process Temperature

Posted on August 27, 2013

True - Any sensor will measure temperature.

 

False - The measurement always represents the process actual temperature.

 

We have proven time after time that the sensor selection and the interface of the sensor with the process will turn a measurement into a confident measurement.  Which would you like?

 

Recent tests on stem conduction, specifically at very cold temperatures, reinforced our commitment to discussing the installation with our customers.

 

Don't be fooled by the specifications as they are typically only to compare sensor designs based on tests in the laboratory according to ASTM or IEC.  Be aware that these standards define stem conduction differently.

What really matters??  The details of the installation.  Various solution options exist to ensure confidence in the measurement at the temperatures you are concerned about....   even when the target immersion is a challenge.

Food Safety - Temperature matters!

Posted on August 15, 2013

The food industry is challenged with bacteria that evolves as fast as the processes to manage them.  Listeria and Salmonella, the 2 big challenges, not to mention E. Coli, are changing and becoming more heat and chemical resistant.

 

 

The result is biofilms that grow quickly and are tougher to eradicate.  The treatment approaches gaining ground are enzyme based chemical that breakdown the biofilm and help expose the bacteria so that the cleaners and sanitizers can work their magic.  The belief is that sanitization is about 95% effective.  It is good that the human intestinal system can deal with that possibility of 5%.

 

The food industry works hard to keep their facilities and systems clean - from the loading dock to the processing equipment.

 

We have learned that the cleaners and sanitizers work best within a temperature range specified by the manufacturers.  Enzymes are most effective between 120°F and 150°F.  The sterilization process typically involves steam at ~~ 250°F.  Sterilization is more costly to perform, although with accurate temperature monitoring to insure saturation, it is the only process that is 100% effective.

 

Thank you to the Food Processors for their diligence and dedication to these important processes and cleaning regiments - we as consumers truly appreciate your efforts...

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.

There is a lot of focus in the Biotech and BioPharma industry on single use and disposable processing equipment.  The drive to achieve sanitary operation, reducing risk of contamination, and the mounting expense to build and operate large facilities has brought this conversation and system development to the forefront.  The equipment and systems involved with single use and disposable processing demand new, creative, and highly effective instruments.  Temperature is a critical parameter to ensure efficient  and effective operation. bioreactor.jpg

 

The Bioreator PRT was specifically designed for Bioreactor bag style systems, and offers industry-leading accuracy, stability, and short-term repeatability performance.  Bioreactor Sensor information.

 

We have customized this and multiple other sensors to help many Biotech and BioPharma companies achieve confident temperature measurement while reducing the effort of CIP and SIP through single use and disposable operations.

 

Don't see what you have in mind?  Contact Burns and we'll design a sensor for your specific needs.
