Clogged Air Filter Sensor
D6A
Detect Clogged Fan Filters to Prevent
Overheating of Equipment
H
Sensor detects air flow over a 0.5 to
1.5 m/sec range; provides analog
voltage output of 0 to 5 VDC
H
Algorithms provide a temperature
reference point to determine if a filter
fan is moving the right amount of air
H
Wide operating temperature range: 0 to
45C
H
Low current consumption: 60 mA
H
Ideal for computer servers, routers and
network devices; uninterruptible power
supplies and cash registers

HANDLING
1. Do not apply a voltage of 13.2VDC or more.
2. The output voltage decreases when oil, moisture and dust
adhere to the thermally sensitive resistor. Wipe down the
resistor during maintenance.
3. The output voltage decreases when the terminal winds when
the thermally sensitivie resistor is cleaned.
4. An internal circuit can be short-circuited when water or dust
reaches the printed circuit board.
5. Avoid electrical shock. Do not touch the thermally sensitivie
resistor terminal with fingers or hands.
6. Avoid serious burns. Do not touch the thermally sensitive
resistor because it is heated to 80C.
7. Dispose of the sensor properly when it no longer operates.
