The Candlestick Sensor is narrow and low profile to minimize the disturbance of the heat flow in the test domain. It features a flexible, plastic-sleeved stem, which facilitates installation and repositioning during the testing process. Air velocity and temperature sensors are calibrated for low (natural convection) and high velocity flows. They are capable of temperature measurements ranging from -20° to +120°C ±1°C. Velocity measurements range from 0 to 50 m/s (10,000 ft/min) ±2%, depending on the particular model of sensor. The use of a single sensor to measure both temperature and velocity eliminates errors that can occur when airflow is non-isothermal. Multiple Candlestick Sensors can be easily installed to thoroughly map a system’s thermal and airflow conditions. Their robust nature allows for continuous repositioning and reading.
