The air velocity transmitter, AVT, is used for measuring air velocity and air volume in ventilation systems.
Air velocity sensor AVT
AVT-D-R: relay model is always equipped with display. The switching point and the hysteresis of relay can be configured by jumper, pushbutton and display user interface. AVT-D for display, -R for relay.
Technical data
| Type | Measurement range (velocity) | Accuracy of velocity | Measurement range (temperature) | Accuracy of temperature | Supply voltage | IP Class |
| AVT | 0...2, 0...10, 0...20 m/s | <0,1m/s +5% from reading | 0...50ºC | <0,5ºC (v > 0,5m/s) | 24VDC/24VAC ± 10% | IP54 |
| AVT-D | 0...2, 0...10, 0...20 m/s | <0,5m/s +5% from reading | 0...50ºC | <0,5ºC (v > 0,5m/s) | 24VDC/24VAC ± 10% | IP54 |
| AVT-D-R | 0...2, 0...10, 0...20 m/s | <1,0m/s +5% from reading | 0...50ºC | <0,5ºC (v > 0,5m/s) | 24VDC/24VAC ± 10% | IP54 |
| AVT-R | 0...2, 0...10, 0...20 m/s | <1,0m/s +5% from reading | 0...50ºC | <0,5ºC (v > 0,5m/s) | 24VDC/24VAC ± 10% | IP54 |
