These MiniAir 6’s are Steel vane anemometer for high temperature air and gas flows with a separate electronics housing with a linear voltage output. The separate electronics housing allows the Steel anemometer to be used for air flow measurements up to 250°C. The MiniAir 6 provides a 0-2V output relative to flow velocity ranges of up to 20m/s or 40m/s with Micro and Mini sized turbines. The sensors are simple to install and can be easily integrate into a fixed system with other instrumentation including data loggers or displays.
The MiniAir6 range of anemometers are designed with three separate parts. The vane anemometer, probe handle and separate electronics housing. The snap head, a probe handle and a separate elecronic housing. The Steel snapheads are designed for aggressive gases and are not replaceable. These probes are suitable for higher temperatures applications, up to 250°C.
In anemometry, the accuracy achieved by a vane probe is acknowledged to be unmatched. The vane rotation is closely linear to flow velocity and is unaffected by pressure, temperature, density and humidity. In the MiniAir probes, as each metal blade passes the probe handle, a pulse is generated by a simple magnetic pick up in the handle. The electronics in the separate housing reads the pulses generated and converts these readings to a linear 0-2V output signal.
The MiniAir Steel vane anemometers are available in two different sizes, Micro and Mini, with two different flow ranges available for each: 0-20ms; and 0-40m/s. Each anemometer has a different starting flow velocity due the differences in the initial combination of size and flow velocity have slightly different start up flow velocity as a certain flow is required to overcome the initial stationary friction forces of the individual turbines. This varies with the size, range and blade materials. All outputs are ranged from 0m/s and the anemometers will provide readings below the initial start up speeds once the turbines have some momentum.
Separate units are available with a replaceable plastic and Aluminium vane for non-aggressive gases and Steel anemometers for high temperature applications up to 140°C, as well as a Brass heads with Aluminium blades.
