MICROPROCESSOR VANE ANEMOMETER mAS3

TECHNICAL DATA

Measuring range: 0.2 - 20 m/s

Uncertainty of measurement: 0.5 %

Velocity measurement methods and averaging periods:

• instantaneous velocity measurement: 1 sec.

• average velocity measurement: from 1 sek. to 3600 sec.

Ingress protection of electronic circuit: IP54

Diameter of measuring head: f = 98 mm

Maximum ambient temperature: 5 - 45 deg. C

Battery power supply, continuous operation for - 15h

Mass (excl. casing): 470 g

STANDARD EQUIPMENT

• user guide

• genuine leather casing

• power supply for charging of battery

Optional equipment:

• extension rods of various type and length (from 0.5 to 4.5 m)

• RS232 interface + Windows software (2002 model)

Optional intrinsically safe version EX:

• Exia I category (approval of the Polish State Mining Authority)

• category - Exia I/IIC T4

This is the unique device of such class on Polish market with a user defined averaging time and intrinsic safety category IIC.

This model, developed at the Institute has won a prize on THERM'98 fairs.

In year 2002 we introduced a modified version of mAS3. Cover protecting the measuring vanes is made of acid-resistant steel 316L and optical indicator signals averaging.

Optionally it can be equipped with RS232 interface and standard software, on demand the software can be customized to the user's needs i.e.:

• printing protocols of ventilation system acceptance

• research on changes of volumetric flow (i.e. due to window replacement)

Modifications allowed us to extend guarantee period to 36 months!

Each of our anemometers has a Calibration Certificate accepted by the Polish Standard Office and the set of documents which, by Polish law is required for measurements in gas or vapour explosion hazard atmospheres.
