描述

聯絡供應商

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)

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
