Measure Temperature and Air Velocity with Candlestick Sensor

After sizing a heatsink and fan, system designers may want some data to show the heatsink and fan are doing the job. For these and other characterization of thermal conditions in electronic systems, Advanced Thermal Solutions MS 1000-CS-WC could provide the answer and data they need. The candlestick-shaped sensor has a 0.5 mm in diameter stem and 9.5 mm base diameter to provide minimal intrusion into the system airflow. Heights of 9, 12 and 20 mm are available.

Calibrated for both low, natural convection and high velocity flows, the sensors address temperature measurements ranging from   -30 to +150°C ±1°C and velocity measurements from 0 to 50 m/s (10,000 ft/min) ±2%.

Honeywell Zephyr Digital Airflow Sensors Provide 2.5% Accuracy

Using a microelectromechanical system (MEMS) sense die and an Application Specific Integrated Circuit (ASIC) for signal conditioning and interfacing, Honeywell’s Zephyr Digital Airflow Sensors achieve 2.5% accuracy. The fully calibrated and temperature compensated HAF Series are available in standard flow ranges of ±200 SCCM and ±1000 SCCM.

 The MEMS design has thermally isolated heater and temperature sensing elements, providing a fast response to air or gas flow.  The ASIC provides an I²C digital output to simplify interfacing to microcontrollers. A 3.3 Vdc voltage option, low power requirements and small size make the units well suited for battery-powered and portable applications.
