The Engineering folks at Burns are always looking for interesting temperature measurements and devices. Well here are a few of our latest finds. These are not typical PRT’s or RTD’s. They are unique and highly custom applications of classic technology and cutting edge brilliance.
If you have a fever or are planning a climb of Mt Everest you may find this device of interest. The ultimate Sanitary RTD.
Remember, it’s for single use only..
From Nova, Jan 2006; the Thermal Radio Pill was presented as part of the article on understanding the health issues during high altitude climbs.
This next device called a Shot Noise Thermometer presented by Yale in 2006 is nearly Quantum Physics based technology. This idea relates noise, not audible noise but electrical noise, to temperature. The intention is to develop this device into an operating primary standard for temperature down to 0.01 Kelvin. Calibration of this device is certainly a metrology challenge, covering multiple measurement techniques and requiring sub-millikelvin combined uncertainties.
In the area of Quantum Mechanics, is Nanotechnology. The International Nanotechnology Business directory shows some Nano-Pictures. Take a look! Then come back and see what Nanoway Cryoelectronics , a company in Finland is working on. Nanoway is launching a test program for their CBT (Coulomb Blockade thermometer) sensor chip. This Nano based device operates in the near absolute zero range.
We just thought these were fascinating and wanted to share.

On a lower tech level I’m always fascinated by the thermometer readout in my car. I wonder where the actual sensor resides? Sometimes the radiant heat from the blacktop on a hot summer day (something we are looking forward to here in MN) seems to drive the reading up quite a bit higher than the general ambient temperature!
