Advanced Thermal Solutions Temperature & Air Velocity Candlestick Sensor

Advanced Thermal Solutions Temperature and Air Velocity Candlestick Sensor is a robust, base-and-stem design sensor that measures air temperature and velocity for the thermal characterization of electronic systems. The low profile of the Candlestick sensor introduces minimal disturbance in the test domain. It features a polyimide-sleeved stem, which facilitates installation and repositioning during the test set-up. Sensors are calibrated for low (natural convection) and high velocity flows. They are capable of air temperature measurements ranging from -10°C to +120°C ±1°C. Velocity measurements range from 0 to 50m/s (10,000 LFM) ±2%.

The use of a single sensor to measure both air temperature and velocity at the same location eliminates errors that can occur when airflow is non-isothermal. Advanced Thermal Solutions Multiple Candlestick Sensors can be easily installed to provide a detailed map of a system’s thermal and airflow conditions. Their robust and flexible nature allows for the continuous repositioning of the sensor in the test domain.


  • Measures from 0 to 50m/s with no need to change the sensor for a different flow
  • Offers highly accurate readings in Hot Wire Anemometry in electronics cooling
  • Ideal for conditions where rapid measurement of flow control is required
