AIrflow detector is key to thermal
management
A novel airflow detector is specifically designed to detect clogged conditions in air filters on servers and other types of computer equipment efficiently.
A novel airflow detector is specifically designed to detect clogged conditions in air filters on servers and other types of computer equipment efficiently Aimed especially at large server farm type installations, the Omron D6A-N sensor uses thermistors to measure the velocity of the air passing through the air filter, detecting when filters become clogged with dust particles more efficiently than a conventional time totalling meter

Quick-release range of 22mm pushbutton switches
Omron launches new 22mm pushbuttons New from Omron is the easy-connection / quick-release A22 range of 22mm pushbutton switches.
The D6A-N uses a microprocessor with a complex algorithm that together with one thermistor heated to 80C, acting as a temperature reference point and the other subjected to the ambient air temperature flow, determines if a filter fan is moving the right amount of air.
By designing an appropriate response to the 0-5V output signal from the detector, system engineers can provide a reliable indication of which servers' filters need cleaning or replacing, before a more serious and costly fault develops.
Driven from a standard 12V DC supply, the sensor is installed vertically in the air flow being monitored.
It is simply fitted, using nylon rivets.
