Hot Wire Probe Air Velocity Transmitters, LCD

Product Details

OverviewThe EE75 series air velocity transmitters were developed 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 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 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 DegreeC (-40 to 248 DegreeF).In addition to air velocity and temperature values, the transmitter calculates the volumetric flow rate in m/min or ft/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 analogue outputs.The configuration software included in the scope of supply allows to choose the appropriate output parameter and freely scale the display range and signal level of the two analogue outputs. In addition user-friendly calibration of the air velocity and temperature and the adjustment of key parameters (e.g. response time of the velocity measurement, low flow cut-off points, etc.) are supported as well.An optional illuminated display with two control buttons integrated into the cover is available. In addition, this enables changes of the configuration to be made directly on the unit.The EE75 series has a robust metal housing to protect against possible damage in rough industrial environments. There are four different models, providing a comprehensive range of mounting options.Mounting optionsModel A for wall mountingModel B for duct mountingModel C with a remote probeModel E with remote probe, pressure-tight up to 10bar (145psi)The EE75 series can be used to measure the velocity of other gasses as well, although a correction has to be applied to the unit at the factory.Typical ApplicationsMonitoring incoming and outgoing air (energy management) in HVAC applicationsFilter monitoring and laminar flow control in cleanroomsExhaust systems, exhaust hoods and glove boxes in the pharmaceutical, bio and semiconductor industriesMass flow measurement during incineration processesMonitoring and measurement of compressed air systemsAir conveying systemsWind tunnels and climate simulatorsFeaturesHigh accuracyWorking range 040 m/s (08000ft/min) and -40120 DegreeC (-40248 DegreeF)Measurement of air velocity and temperature calculation of volumetric flow rate low dependence on the angle of inflow probe diameter 8mm (0.3") remote probe up to 10m (32.8ft) easy mounting and maintenanceCorrection for pressure, humidity and media-low flow cut-off pressure tight up to 10bar (145psi)SI and US units selectable
