The Series AVU Air Velocity Transmitters from Dwyer Instruments are suitable for measuring clean 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 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 sensing elements are clad in metal ensuring a long service life and enabling the sensors to be cleaned easily. Product Applications: Supply and exhaust fan tracking; Clean room systems; Air pollution studies and manufacturing; Zone control in HVAC systems. Specifications: Service: Clean air and compatible, non-combustible gases. Accuracy: AVU: ±5% of FS; AVUB: ±8% of FS. Response Time (90%): 5 sec (typical). Temperature Limits: 32 to 122°F (0 to 50°C). Humidity Limit: 0-90% RH, non-condensing. Power Requirements: -A models 24 VDC +10% - 15%; -V models 24 VDC or 24 VAC +10% - 15%. Output Signal: -A models 4 to 20 mA current loop; -V models 0 to 10 VDC. Loop Resistance: (-A models) 700 ?. Current Consumption: 60 mA + output current. Maximum Start Up Current: 85 mA; 10 V. Output Current Limit: (-V models) >10 mA. Electrical Connections: Screw terminal. Cable gland for 4-8 mm wire (16 gage wire). Enclosure Rating: NEMA 6 (IP67) except sensing point. Probe Dimensions: 9.45 x .75" (240 x 19 mm). Mounting Orientation: Unit not position sensitive. Probe must be aligned with airflow. Weight: 8.8 oz (250 g). Agency Approvals: CE. Country of Origin, UK.
  • VERSATILE AIR FLOW MONITOR: Monitor air velocity in HVAC measure and control applications: building control and energy mgt systems, supply and exhaust fan tracking, cleanrooms, air pollution control, zone control, VAV systems. Versatile 25 VAC or VDC power input, two signal outputs and two accuracy levels to meet most needs.

  • ACCURATE AND DEPENDABLE: Cutting edge sensor design insures virtually no drift. Accurate over the whole air velocity range. Choose ±5% or ±8% Full Scale accuracy to meet your budget and application.
