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... . |
Self Heated Transistor Digitizes Airflow: 03/14/96 EDN-Design Ideas |
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... |
