Description
- Dwyer series 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 offers 5% accuracy at a surprisingly low cost, with six units covering ranges from 0-785fpm to 0-3150fpm, with either 4-20mA or 0-10V DC output
- 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
- Specifications:
- Service: clean air and compatible, non-combustible gases
- Accuracy: ±5% of full scale
- Response time (90%): 5sec (typical)
- Temperature limits: 32 to 122°F (0 to 50°C)
- Humidity limit: 0-90% RH, non-condensing
- Power requirements: -A models 24V DC +10% - 15%; -V models 24V DC or 24V AC +10% - 15%
- Output signal: -A models 4-20mA current loop; -V models 0-10V DC
- Loop resistance: (-A models ) 700Ω
- Current consumption: 60mA + output current
- Maximum start up current: 85mA, 10V
- Output current limit: (-V models) >10mA
- Electrical connections: screw terminal, cable gland for 4-8mm wire (16 gauge wire)
- Enclosure rating: NEMA 6 (IP67) except sensing point
- Probe dimensions: 9.45 x .75" (240 x 19mm)
- Mounting orientation: unit not position sensitive, probe must be aligned with air flow
- Weight: 8.8oz (250g)
- Agency approvals: CE
