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.

The Series AVU Air Velocity Transmitters from Dwyer Instruments are suitable for measuring air velocity within a duct and giving 4-20 mA or 0-10 V linear outputs. A typical application would be in a VAV air conditioning system.

The transmitters operate by measuring the heat loss from one of two sensing elements in the airstream and hence calculating the air velocity. The special design of these elements makes the transmitter accurate over the whole air velocity range and gives excellent immunity to drift.

The sensing elements are clad in metal ensuring a long service life and enabling the sensors to be cleaned easily.

Installation:
Electromagnetic Compatibility
Series AVU Air Velocity Transmitters have built in immunity to electrical interference. However, to achieve full immunity meeting the standards described below, a screened cable must be used correctly. The cable screen must be earthed at the enclosure of the controller/power supply and connected to the screen inside the AVU casing using the procedure described on the back page. The inside of the transmitter and the sensing elements near the end of
the probe must be protected from electrostatic discharge at all times.
