Specialty Sensors Overview
Application specific air velocity & temperature sensors meet specialized needs for critical containment and electronics development, and monitor airflow in industrial applications. Choose from sidewall, inline, and board mount sensor head styles.
Specialty sensors use dual-sensing elements to measure air velocity and air temperature simultaneously. The sensor element is built remotely from the sensor electronics, which is advantageous for those systems involving high EMI sensitivity or extreme temperatures, or where the sensing area is limited. Application specific air velocity sensors are configured to order with choices for supply voltage, sensor head style, velocity range, and analog and digital communication outputs.
Sensor Heads
Sidewall sensors act as flow-through devices and are well suited for applications where clean, ambient air can be drawn in, rather than contaminated exhaust air, to measure airflow. (Sidewall is leftmost air velocity sensor in image above.)
Inline sensors are designed to retrofit failed legacy products, or those which are no longer accurate enough for new standards. They are typically mounted inside a cabinet plenum area to increase the tamper-resistance of the sensor element. Inline sensors can be quickly installed and connected by splicing into the ½” flow tubing being used by an existing airflow monitor. Tubing is included with inline sensors. (Inline is middle air velocity sensor in image above.)
Board mount sensors consists of a sensor body for sensor electronics, and remote, board-mount sensor head, giving users the freedom to embed the tiny sensor head into printed circuit board assemblies for real time air velocity and temperature measurements. With segregation of the sensing element and sensor electronics, valuable space on the test board is not used up by sensor electronics. (Board mount is rightmost air velocity sensor in image above.)
Applications
Application examples include sidewall sensors measuring face velocity of fume hoods & biosafety cabinets, inline sensors as upgrades to legacy airflow monitors in laboratories, and board mount sensors enabling precise testing of thermal load cards and product evaluation boards. Board mount sensors are used in the development of smart heat-sink designs as well, where real time air velocity or air temperature data is used to speed control fans.
