Featured Product - Underwater Sensor
Posted on March 11th, 2014

The Burns underwater RTD is designed for measuring water temperature in power plant cooling ponds, municipal waste water discharge, and other similar applications.   Construction is 316 / 304 SS, and nylon for long term corrosion resistance.  Heavy duty neoprene insulation on the 18 AWG cable insures long life and accurate measurement.  Available with cable lengths up to 500 feet in 3 or 4 wire circuit arrangement, the sensor follows the IEC 60751 and ASTM E1137 standards for a 100 ohm, 0.00385 coefficient platinum sensor.  Sensor and cable are completely waterproof and corrosion resistant and can be laid directly on the pond bottom or suspended. underwater_sensor-a.JPG 

Available with a 304 SS guard tube that provides additional durability and impact protection. 

See the drawing.

Accuracy up to ± 0.15°C at 10°C (50°F) is available when the “05″ interchangeability code is selected.  Standard accuracy is ± 0.30°C at 10°C (50°F).

Featured Product; Easy-Removal Sanitary Sensors
Posted on January 3rd, 2014

In the sanitary process environment, clean and easy management of the sensing instruments is crucial.

The thermowell and the sensor are installed utilizing a hygienic clamp union.  Removal of the sensor is easy and convenient in support of calibration or replacement without disturbing the thermowell or opening the processing system.

Measuring the Actual Process Temperature
Posted on August 27th, 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.

Fascinating! 

The Food industry works hard to eliminate E. Coli and the BioTech industry embraces E. Coli.

Food Safety - Temperature matters!
Posted on August 15th, 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 29th, 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.

autoclave-by-steriflow.jpgFrom 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.
