UAS1000 EF Airflow Velocity Sensors for Thermal Analysis of Circuit Boards

January 26, 2023 | Posted By: Degree Controls Inc.

UAS1000 EF Sensors allow OCP NIC 3.0 designers to test PCBAs, optimize thermal designs, and define cooling capability for cards.

The 2022 OCP Global Summit held in October covered NIC (network interface card) 3.0, just one of the OCP community’s many projects supporting the growing demands on computing infrastructure and next-generation datacenters. Thermal testing of OCP NIC 3.0 cards is a must, and thermal design guidelines of the OCP NIC 3.0 specification state that “The actual cooling capability of the card shall be defined based on the testing with the OCP NIC 3.0 thermal test fixture”. Details of the thermal test fixtures, including predefined locations for air velocity and temperature sensors, are provided in the OCP NIC 3.0 specification.

Degree Controls UAS1000 Electronics Focused (EF) sensors provide measurements for both airflow velocity and air temperature. The UAS1000 EF is a low-profile, right-angle sensor and is easily secured to a fixture PCB with adhesive or a cable tie. Remotely located on a thin, highly-flexible, 3-meter flat cable with convenient USB connector, the EF sensor provides ready access to compact and distant locations. With choices for velocity range, the UAS1000 EF measures air velocity and air temperature simultaneously, and is capable of ± 3% velocity accuracy.
