Industrial SF-ESP-1 Thermal Airflow Probe Sensor

Industrial SF-ESP-1 Thermal Airflow Probe Sensor is an Electra-Flo component designed for installation in ductwork, with a 20" by 30" duct size specification. As part of Air Monitor's ELECTRA-flo thermal dispersion family, the SF-ESP-1 uses multi-point thermal sensors to determine the average airflow and air temperature inside a duct, providing a single, representative flow reading for the system. The probe is intended to be used with ELECTRA-flo probe arrays, which place several sensing points along the duct to condition turbulent flow and improve measurement accuracy, thanks to aerodynamic sensor apertures that condition turbulent airflow. By capturing both velocity and temperature data, the SF-ESP-1 supports monitoring, balancing, and verification activities in commercial and industrial HVAC applications, where precise airflow information helps ensure design compliance and consistent indoor air quality. Typical deployments include large-diameter supply and return ductwork in office buildings or facilities with demanding air-handling requirements, where reliable, repeatable measurements are essential for commissioning and ongoing performance checks. The SF-ESP-1 embodies the ELECTRA-flo approach to airflow measurement, emphasizing modular, probe-based sensing that can be integrated into broader monitoring architectures within HVAC systems.
