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.GS41AV
We supply the GS41AV without a sensor, if you require a sensor, please order this from Eltek separately.
The E plus E EE660 is a sensor for measuring very low air velocity. A thin film sensor operates on the hot film anemometer principle and provides excellent accuracy to 0.15m/s (30ft/min) whilst demonstrating a high insensitivity to pollution. The EE660 is non directional and also ideal for in -duct laminar flow applications.
The EE660 operates from a 24VDC supply and when used with the Eltek GS41AV transmitter provides comprehensive air velocity data, ideal for building ventilation studies before and after retrofits.

The E plus E EE576 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.
