Do you need to prototype, test, and validate electronic or electromechanical control system designs? Degree Controls has USB sensors which measure air velocity and air temperature simultaneously using dual sensing elements. A variety of compact sensor head styles are available, to accommodate a wide range of airflow applications. The UAS1000 RF (reference) with board-mount sensor head is a popular sensing solution for testing the airflow of printed circuit board assemblies (pcbas). The reference sensor consists of a UAS1000 sensor body with sensor electronics, and separate sensor head, giving users the freedom to embed the sensor head into a pcba for real time air velocity and temperature measurements, without using valuable space on the test board for sensor electronics.


Engineers install UAS1000 RF sensors onto pcb load boards for actual airflow testing. With through-hole micro header, 0.050” pitch, the sensor head is soldered directly to a pcb, or plugged into a surface mount socket for easy removal, ideal for plug-and-play test strategies with flexible measurement locations. Traces are run on the load card from airflow sensor locations to PCB mount connectors. UAS1000 sensor bodies then make the connections from the load card to a PC or °C Port data acquisition instrument to collect air velocity and temperature data in real time.

Use the UAS1000 RF airflow sensor to validate heat sink performance, thermal flow paths, and chassis cooling methods. By incorporating RF sensors onto pcb load boards, engineers obtain empirical data with which to evaluate thermal performance of printed circuit boards, chassis, and enclosures. Such meaningful airflow data allows research teams to make design improvements, shorten development times, and reduce project costs.

A thermal load board (TLB) is used to simulate an application board such as a motherboard or blade server. It is a tool for the thermal testing of electronics systems and enclosures.
