The EE75 Series air velocity transmitters were developed by E+E Elektronik in Austria, to obtain accurate measuring results over a wide range of velocities and temperatures.
A high quality hot film sensor element based on cutting-edge thin film technology ensures maximum sensitivity, even at low mass flows. At the same time, the innovative probe design produces reliable measuring results at high flow velocities of up to 40 m/s.
The integrated temperature compensation minimises the temperature cross-sensitivity of the EE75 series which, combined with the robust mechanical design, allows it to be used at process temperatures between -40 and +120°C.
The transmitter calculates the volumetric flow rate in m3/h. The cross section of the duct needs to be determined for this purpose and the volumetric flow rate can be displayed and directed to one of the further measurements. The configuration software included in the scope of supply allows one to choose the appropriate output parameter and freely scale the display range and signal level of the two analog outputs. User-friendly calibration of the air velocity and temperature and the adjustment of key parameters are supported as well. The EE75 Series comes in robust metal housing, which protects it from any possible damage in rough industrial environments.
Typical applications for this series of transmitters would include monitoring of incoming and outgoing air (energy management) in HVAC applications; filter monitoring and laminar flow control in clean-rooms; exhaust systems, exhaust hoods and glove boxes in the pharmaceutical, bio and semiconductor industries; mass flow measurement during incineration processes; monitoring and measurement of compressed air systems; air conveying systems and wind tunnels and climate simulators.
