Chapter 8: Products and Applications


while many of the earlier chapters of this volume have explored the physics and technology behind non-contact temperature measurement, now it's time to delve into the wide array of products that are available to take advantage of radiation phenomenaand how they're applied to industrial use.

Non-contact temperature sensors allow engineers to obtain accurate temperature measurements in applications where it is impossible or very difficult to use any other kind of sensor. In some cases, this is because the application itself literally destroys a contact-type sensor, such as when using a thermocouple or resistance temperature detector to measure molten metal. If the electrical interference is intense, such as in induction
heating, the electromagnetic field surrounding the object will cause inaccurate results in conventional sensors. A remote infrared sensor is immune to both problems.

For maintenance, no other sensor is able to provide long-distance, noncontact temperature measurements needed to find hot spots or trouble areas in distillation columns, vessels,
insulation, pipes, motors or transformers. As a maintenance and troubleshooting tool, it's difficult to beat a hand-held radiation thermometer.

Although non-contact temperature sensors vary widely in price, they include the same basic components: collecting optics, lens, spectral filter and detector. For more detailed technical
information on each sensor type, see the previous chapters.

Topics covered include:
1.  Alternative Configurations
2.  Application Guidelines
3.  Accessories and Options


Other chapters of Transactions will systematically cover other aspects of temperature, humidity, pressure, strain, flow, level, pH, and conductivity instrumentation as well as other measurement, data acquisition and control topics. Click here to view the other chapters of Volume I, or to download Non-Contact Temperature Measurement in its entirety.

 
We hope the Transactions in Measurement and Control series will find a permanent home on your reference shelf, and that it proves itself of great value now and in the future.
