High-precision Air And Gas Velocity Transmitter

We are engaged in manufacturing and exporting of High-Precision Air And Gas Velocity Transmitter to our patrons. The AV 75 series air velocity transmitters were developed to obtain accurate measuring results over a wide range of velocities and temperatures.
Ahigh-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 Av75 series which, combined with the robust mechanical design, allows it to be used at process temperatures between -40 to +160A C (-40 to 320A F).

n addition to air velocity and temperature values, the transmitter calculates the volumetric flow rate in mA /min or ftA /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.
