| Specification | Description | ||
|---|---|---|---|
| Standoff mounted sensors | One or two sensor assemblies for each fan are cantilever-mounted to the face of the fan for correct positioning of the sensor into the airstream. | ||
| Sensor distribution | You can mount up to two sensor assemblies for each fan.
When you use two sensor assemblies for each fan, position the sensors
opposite each other at the fan inlet. Note: On dual
inlet fans, you only require two sensor assemblies to sample the
flow from the entering airstream.
