Series AVU Air Velocity Transmitter

ideal for building automation systems, ±5% or ±8% full scale accuracy

the seris avu air velocity transmitter is ideal for a wide range of hvac measurement and control applications, particularly in complete building control and energy management systems. The series avu transmitter operates by measuring the heat loss from one of the two sensing elements in the air stream, then calculating the air velocity. Units are virtually immune to drift due to the design of the sensing element,which makes the transmitter accurate over the whole air velocity range.

calibration option available under accessories.

product applications

supply and exhaust fan tracking,clean room systems,air pollution studies and manufacturing,zone control in hvac systems
