Candlestick sensor promises accurate thermal measurements

Advanced Thermal Solutions has rolled out its candlestick–style sensors available in three heights. According to the company, the devices simultaneously measure air temperature and velocity to allow engineers to characterise thermal conditions inside electronic systems. The narrow, low–profile base–and–stem design of the sensors cuts the disturbance of airborne heat flow in the test area to guarantee accurate measurements.

The use of a single sensor to measure both temperature and velocity eliminates errors that can occur when airflow is non–isothermal, while multiple sensors can be used to thoroughly map an entire system's thermal and airflow conditions. Each sensor has a polyimide–sleeved stem that allows continuous repositioning.

Calibrated for low and high velocity flows, the sensors have a temperature measurement range of –20°C to 120°C, accurate to within ±1°C. Velocity measurements range from zero to 50m/s. Candlestick sensors come in heights of 9mm, 12mm and 20mm. The base diameter of all models is 9.5mm. Stem diameter is 0.5mm, and bead diameter is 1.1mm.
