Description
The AVT-D-R is an all in one air velocity and temperature transmitter suitable for HVAC applications and can be used for measuring air velocity, temperature and air volume in ventilation systems. Air volume is calculated from the air velocity and the duct diameters. Each unit has a display and relay outputs in addition to the standard dual analogue outputs of 0-10V and 4-20mA for velocity and temperature.
Applications
- Monitoring air velocity and temperature in ducts
- Monitoring air volume based on air velocity and duct diameter
- Monitoring the proper use of air filters
(proper air velocity = proper functioning of filters)
Features
- All measurement ranges in a single device
(0…2 m/s, 0…10 m/s, 0…20 m/s) - Separate outputs for air velocity and temperature
- Available with relay output
- Easy to install on round and rectangular ducts
