SERIES AVPT | PENCIL STYLE AIR VELOCITY TRANSMITTER
®
FEATURES/BENEFITS
• Sensing elements have been coated with an engineered conformal coating to ensure durability and longevity
• Varying lengths for easy installation
• Functionality at temperatures below freezing
DESCRIPTIONAPPLICATIONS
• VAV systems
• Building ducts
The Series AVPT Pencil Style Air Velocity Transmitter uses thermal
anemometer technology to provide high accuracy and stable air velocity
measurements in imperial and metric units. The Series AVPT can be
congured with either a voltage output or BACnet MS/TP communication
to provide universal inputs to a variety of monitoring equipment. Models
are available with xed cable lengths of 20 or 78 inches with ying leads
or a 5-pin M12 connector on a 24 inch cable. Probes are available in
lengths of 6 or 12 inches. A mounting ange included with the product
provides the ability to vary insertion depth.
Models are available in 3% or 5% accuracy to suit a variety of applications,
while the optional BACnet MS/TP communication protocol allows units to
be daisy-chained to provide access to all of the velocity and temperature
measurements.
Service Clean air.
