Description
The MIEX06112 is a synthetic plastic micro snap head with an Aluminium vane impeller and separate external electronics. The external electronics box should be located in a safe area outside the hazardous area and operates as a zener barrier to the probe and your monitoring equipment. The electronics provides a linear 0-2V output signal for a flow velocity range of 0-20m/s. The probe has a starting flow velocity of 0.5m/s but can provide readings below this once the impeller has started moving. The ‘Micro’ head is smaller than the probe handle and allows the sensor to be inserted into a compression gland and only requires a minimum access diameter of 16mm. The Micro head is ideal for measuring flow rates in ducting and other small pipe work, or any applications where a probe needs to be inserted and secured in place

Snap-Head Replacement
The MiniAir units with external electronics still use the same snap head fixing system, which allows a new impellar to be fitted to the probe handle quickly and easily. Saving cost caused by non-productive time or by allowing a damaged turbine to be replaced without the need to replace a whole probe and/or electronics. The old snap head just needs pulled directly from the handle and a new snap head fitted by pushing it onto the handle. This allows users to have a probe back in service in a matter of seconds by simply changing the snap-head.
Every MiniAir probe head generate a pulse each time a vane blade passes the probe handle and the MiniAir 6 electronic box converts the output to a linear 0-2V output. Each snap head and probe handle are paired and any replacement snap head should be of the same original size and flow range. Fitting an incorrect snap head will not match the probe handle and therefore the MiniAir 6 will no longer provide an accurate output, as will trying to us a different sensor with the incorrect electronics box.
