GenII - Model GS41AV -Transmitters for Air Velocity Monitoring
The GS41AV transmitter is designed for use with the E plus E series of air velocity sensors, types EE660 or EE576. Highly accurate readings can be achieved down to 0m/s. The combination has proved ideal where air laminar flow in ducted heating / ventilation systems in domestic or industrial installations needs to be monitored.
The E plus E sensor head uses a field proven hot-film element to measure velocity by detecting the change in temperature as air moves past it, cooling the element. This technique means the sensor is less sensitive to dust and dirt, giving very stable results. An alignment strip along the probe`s tube allows the user to set a measured probe depth during mounting in a pipe or duct. This provides a method for repeatedly mounting probes to an accurate known depth.
The value logged is the rolling averaged value over a three minute cycle, meaning that transient values or deviations from the norm are not lost when logging.
