Fan-Aspirated Temperature/Humidity Sensor compensates for parasitic heating due to electrical power dissipation and/or exposure to solar radiation.

  • Internal fan constantly draws air in over the sensor, providing highly accurate temperature readings.
  • Ideal for installations where steep temperature gradients are common, and where there is little to no air flow.
    • Use in freezers where there is intermittent air flow.

Key Features:

  • Applications from -4 to 140°F (-20 to 60°C) and 0 to 90% relative humidity.
  • Temperature accuracy:
  • ±0.90°F (±0.50°C) for -4 to 14°F (-20 to -10°C).
  • ±0.72°F (±0.40°C) for 14 to 140°F (-10 to 60°C).
  • Inflation due to self-heating: <0.9°F (0.5°C) typical, 2.3°F (1.3°C) max.
  • Humidity accuracy (at 86°F/30°C):
  • 10 to 80% relative humidity, ±3%
  • 80 to 90% relative humidity, ±4%
