Low cost anemometer fights dust:
08/30/2001 EDN - Design Ideas / As higher levels
of power dissipation underscore the need for
cooling, more and more fans are finding their
way into small electronic enclosures. The dust
that fans pull into these enclosures can,
however, cause major problems for
high-reliability systems. By coating heat sinks
and electrically charged components, the dust
acts as a blanket that raises the effective
thermal impedance betw... . |

Thermistors And A Microcontroller
Simplify Anemometer Design:
10/14/02 Electronic Design - Ideas for Design /
Typically, air flow is measured with a hot-wire
anemometer. Here's an alternative version of
that concept using two thin-film platinum
resistance temperature detectors. A
high-performance mixed-signal microcontroller
can make the measurement and drive. . . |
