MiniAir64 Steel Anemometers with Separate Electronic Housing

Quick Overview

These MiniAir 64's are vane anemometer with a separate electronics housing for measuring the flow velocities of corrosive, high temperatures gases up to a maximum temperature of 140°C. The MiniAir 64 will provide a linear 4-20mA output for flow ranges of 0-20 or 0-40m/s. Units with Stainless Steel turbines are also available for use up to 250°C. Probes are available with Micro and Mini sized sensing heads. The sensors are simple to install and can be easily integrate into a fixed system with other instrumentation including data loggers or displays.

Details

The MiniAir64 range of anemometers are designed with three separate parts. The vane anemometer, a probe handle and a separate electronics housing. The probe handle contains a magnetic switch that provides a pulse each time a turbine blade passes the top of the handle. The electronic components are all housed in the separate housing and this housing will accept the pulses from the probe and convert this to the 4-20mA output. The probe has a 5m cable that connects to the electronics housing and there is another 2m cable with flying leads for connecting the output to your own system. The separate electronics housing allows the probe to be used for gas flows up to 140°C, but the electronics housing must be kept below 80°C. Probes for higher temperatures applications, up to 250°C are also available.

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 4-20mA 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.

These units are ideal for corrosive/aggressive air and gas flow measurements. For aggressive applications where the gases may affect Steel, or where the flow is likely to be low, a Brass probe is available. Fully Steel versions are available for high temperature applications up to 250°C. Links for these products, plus the standard MiniAir 64 anemometer with electronics in the probe handles, are provided in the section below.
