Description

The MINI20132 is a vane anemometer probe suitable for use with the MC 4.0 handheld display for monitoring the flows of non-aggressive gases. The probe head is a synthetic plastic construction with a metal turbine that generates a frequency output each time a blade passes the probe handle. The frequency of rotation is almost proportional to the air-flow velocity and largely independent of pressure, temperature, density and humidity. The MC 4.0 converts the rotational frequency into a standard signal and shows the measured value in the display.

The MINI20132 includes the Macro snaphead, which is 85mm in diameter, with a flow range of 0-20m/s. The larger diameter head allows for a lower start up speed and allows the sensor to cover a larger area. The Macro head is ideal for measuring flow rates in open air, or where the air flows may start as low as 0.2m/s. The Mini head require a start up flow rate of 0.4m/s and Micro head requires 0.6m/s.

Cleaning Instructions – MiniAir20 Macro Plastic Probe

As the probes are highly sensitive measuring instruments, they must be cleaned with very great care.

Any fibres, hair or other foreign bodies can be carefully removed with fine tweezers. When doing so, take care not to bend or otherwise damage the vanes or the spindle.

The adjustment of the bearing screws must never be changed. This can result in erroneous measurements.

Never allow hard objects to contact rotating impellers!!!

Cleaning agents which extract the plasticizer from the plastic are never to be used for plastic probes (practically all solvents!).

We recommend the following for cleaning the probes:

– running water
– soapy water
– pure benzine

Cleaning example:

1) Carefully swish the top part of the impeller back and forth in clean, pure benzine for about 10 min. Then swish the top part of the impeller back and forth in clean kerosene for about. 1 min. to re-lubricate the impeller bearings.

If soapy water is used as a cleaning agent it is advisable to wash out the soap solution thoroughly with distilled water before lubrication with kerosene.

2) After cleaning the probe, rub it dry externally with a clean, dry, fluff-free cloth.

3) Leave the top part of the impeller to dry for about 30 minutes.

Only clean the head of the impeller! Probes are on no account to be fully immersed in the solution.

Snap-Head Replacement

The snap-head fixing system renders it very simple to fit a new impeller to the flow probe: this saves costly non-productive time and in the event of damage to the snap-head enables you to have the probe back in service in a matter of seconds by simply changing the snap-head.

MINI20132 is the replacement part for part no. 95.0014.
