Newsletter March Exergen Global: Heat Balance

EDUCATION - OUR ACADEMY
KNOWLEDGE AND INNOVATIONS ARE OUR DRIVING FACTORS

My colleagues and me are fully aware that a productive relationship between you, our partners, customers, distributors,  is based on us providing the feedback and training yo need to understand how our unique infrared non-contact temperature sensors work and how they can be perfectly deployed in a wide range of applications.

We therefore explain a couple of our unique technologies and opportunities:

1. Heat balance

Exergen’s heat balance method measures fluid temperature inside of devices by measuring both the tubing surface and ambient temperature, then calculating the internal temperature necessary to maintain the heat balance. In medical applications this ensures patient safety as it provides a method to measure fluid temperatures non-invasively. A convenient clip head provides a reproducible mounting location for the sensor and can be quickly removed from used tubing and attached to new tubing.

TECH NOTE #88: MEASURING TIRE TREAD INTERNAL TEMPERATURE WITH THE IRT/C-HB (HEAT BALANCE)™ SERIES INFRARED THERMOCOUPLE

By its very nature, infrared measures surface temperature, but most material properties of interest relate to internal (bulk) temperatures. For many materials, such as metals, the gradient between the surface and internal temperatures is small enough to ignore. For other materials, such as rubber products, the gradient can be quite large when the material is exposed to an ambient temperature that is much different from its bulk temperature. This problem is particularly acute in the manufacture and testing of tires, since surface temperature may not be a reliable indication of internal tread temperature, which is the property of interest, due to the action of rapid convection and radiation at the surface, and slow conduction internally.

TECH NOTE #99: IRT/C HEAT BALANCE SERIES FOR MEDICAL APPLICATIONS

The Heat Balance (HB) Series of IRt/c infrared thermocouples have the ability to measure the internal temperature of the target material, non-invasively, by employing a patented heat balance technique. A typical application in medical equipment is monitoring or controlling the temperature of fluid transported through disposable tubing when warming or cooling:

- Transfusion systems

- IV warming systems

- Dialysis systems

- Cardio-pulmonary bypass systems

- ECMO systems

- Blood analyzers
