E+E EE75 Air / Gas Velocity Transmitter

The E+E EE75 Air / Gas Velocity Transmitter are designed for measurements 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 lowest mass flows. At the same time, the innovative probe design produces reliable measuring results at high flow velocities.

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 to +120°C (-40 to 248°F). In addition to air velocity and temperature values, the transmitter calculates the volumetric flow rate in m³/min or ft³/min. 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 analog outputs.

Applications for the EE75 include:

• Monitoring incoming and outgoing air (energy management) in HVAC applications
• Filter monitoring and laminar flow control in cleanrooms
• 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
• Wind tunnels and climate simulators
