Ruskin's EAMP series probe utilizes thermal dispersion technology to measure the airflow in the most demanding applications.
The mathematically defined relationship between heat transfer rate and airflow velocity make it possible to accurately measure flow by elevating a thermal temperature sensor and placing it in the airstream with an ambient air temperature sensor as a reference. The heated sensor is elevated to a stipulated temperature differential above the reference point. The velocity is calculated using the reference point (ambient), the known heat transfer characteristics of the heated sensor, and the power expenditure necessary to maintain the delta between the heated sensor and the ambient reference sensor.
The airfoil shape of the probe, geometry of the calibrated metered orifice (CMO) and placement of the sensors are all based on results from computational fluid dynamics and extensive lab testing. Ruskin's unique design provides lower pressure drop and accurate measurement of flow and temperature.
