Description
The AVT-MOD-D 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. Using the Modbus output greatly reducing the wiring installation as units can be daisy-chained to the next unit in the system. Each unit has a display for local readings.
Applications
- Monitoring air velocity and temperature in ducts
- Monitoring air volume based on air velocity and duct diameter
- Modbus Communications are ideal for large scale Demand Controlled Ventilation (DCV) systems
- Monitoring the proper use of air filters
(proper air velocity = proper functioning of filters)
Features
- Modbus output provides air velocity and temperature to main control unit.
- No voltage drop over long cable runs, readings
- Available with display
- Easy to install with units daisy-chained by twisted-pair cable
