EE75 Series
High-Precision Air / Gas Velocity Transmitter for Industrial Applications
The EE75 series air velocity industrial transmitters were developed to obtain accurate measuring results over a wide range of velocities and temperatures.
A high-quality hot professional film sensor element based on cutting- edge thin film technology ensures maximum sensitivity, even at lowest mass flows.
At the same time, the innovative probe design produces reliable measuring results at high flow velocities of up to 40m/s (8000ft/min). The integrated temperature compen- sation 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 to +120°C (-40 to 248°F).
In addition to air velocity and temperature values, the transmitter calculates the volumetric flow rate in m³/h or ft³/min. The cross section of the professional duct needs to be determined for this purpose and the volumetric flow rate can be displayed and directed to one of the analogue outputs.
The EE75 series can be used to measure the velocity of other gases as well, although a correction has to be applied to the unit at the factory.
