Air velocity transmitters
Air velocity is very important in ventilation systems. What airspeed should be in the ventilation ducts? 4 ... 5 m/s for side branches of air ducts for supply and extraction ventilation; 6 m/s for the main supply and exhaust ventilation channels; 8 ... 12 m/s for the main channels of industrial enterprises. Air velocity transmitters were developed to monitor the air speed in ventilation. The air velocity transmitters are supplied with a duct mounting flange for fast and easy mounting. The duct mounting flange has a neoprene gasket for good sealing into the duct. The depth of the transmitter's probe can be adjusted with the duct mounting flange.
Air velocity transmitter
The air velocity transmitter is developed for air velocity measurement inside ventilation ducts in HVAC systems. The sensor of the transmitter is at the end of its probe to measure air velocity and temperature inside the ventilation duct. This transmitter enclosure has an IP65 protection class. There is one screw and two snap lids on the cover of the enclosure. The air velocity transmitter is delivered with a duct mounting flange, which helps for easy and fast installation. The transmitter probe depth to the ventilation duct can be adjusted with the duct mounting flange.
Features
- Power supply 24 VAC / VDC
- Two outputs for Air Velocity 4 - 20 mA and 0 - 10 VDC
- Ranges 0 - 5 m/s, 0 - 10 m/s, 0 - 15 m/s or 0 - 20 m/s
- Accuracy ± 5 % for 0-20 m/s
- Response time 1 second- or 5-seconds DIP switches selectable
- Protection class IP65
