The MiniAir 60 is a vane anemometer for measuring the flow velocities of gases with a linear frequency output. The MiniAir 60 provides a 0-4vDC/TTL output relative to flow velocity ranges of up to 20m/s or 40m/s with Micro, Mini and Macro sized turbines. The units require a 4.5-5.5vDC power supply and the standard plastic, Aluminium probes can be used up to 80°C, with units available with separate electronics and Steel probes suitable for up to 250°C. The sensors are simple to install and can be easily integrate into a fixed system with other instrumentation including data loggers or displays.
The MiniAir 60 range of anemometers are designed with at least two component parts. A vane anemometer and probe handle. The probe handle contains all the electronic components and comes with 2m cable with flying leads. All plastic heads are designed to be replaceable with an Aluminium vane for non-aggressive gases and a Steel vane for aggressive gases. Probes for higher temperatures applications are supplied with a fully Steel head and turbine that is screwed to the probe handle and is not replaceable.
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 of the MiniAir 60 reads the pulse and converts these readings to a linear frequency signal.
The MiniAir vane anemometers are available in three different sizes: Micro; Mini; and Macro, with two different flow ranges available for each: 0-20ms; and 0-40m/s. The standard probes are a synthetic plastic construction snap head with an Aluminium vane turbine and handle. A Steel vane and handle option is available for aggressive gases and a full Steel anemometer for high temperature applications up to 250°C.
