Duct 3 %
The FAT 142 is a single-point, multi-range air velocity transmitter with user selectable 0-10Vdc or 4-20mA outputs and four user selectable measurement ranges.

The unit has a built-in self-test feature and the user can manually override the output to 0%, 50% or 100% of output range to aid commissioning.


  • User selectable 0-10Vdc or 4-20mA outputs

  • Built-in self-test feature

  • Built-in manual override facility for 0%, 50%   or 100% of output range

  • Durability and resistance to chemical   reagents

  • 0 to 4 m/s, 0 to 8 m/s, 0 to 16 m/s, 0 to 32 m/s selectable ranges

  Accuracy (3% of range):

  • 0 to 4 m/s, 0.12 m/s

  • 0 to 8 m/s, 0.24 m/s

  • 0 to 16 m/s, 0.48 m/s

  • 0 to 32 m/s, 0.96 m/s

A Multi-point Air Velocity Sensor for use in larger ducts or where turbulent airflow is likely to be encountered.

Stainless steel construction is used for the tubing and all gaskets are provided.

The FVP-SS can be connected to a PAV or PATX Differential Pressure Sensor of an appropriate range (please refer to data sheet on AP's website for further information).

The output of the sensor represents the velocity pressure and is defined by the following equation:










  • Mounting plate to suit flat ducts

  • Double gasket seals the probe to the duct

  • Available in lengths from 700mm to 2000mm

  • Push on connectors to suit PA-TUBE-8mm
