USER-FRIENDLY MEASURING DEVICES air flow and velocity transmitters avt series Multifunctional air velocity transmitters for building automation systems The AVT series air velocity transmitters are engineered for building automation in the HVAC/R industry. The AVTs measure air velocity and temperature, with field selectable range and output options in a single device. Designed with a duct mount probe and adjustable collar suitable for round or rectangular ducts. AVT series devices include: • 3 field selectable measurement ranges for air velocity, selectable via jumper (see Model Summary). • Separate readings and outputs for air velocity and temperature. • Proportional output options include: voltage (0-10 V) and current (4-20 mA). AVT series device options offer: • Backlit display • Field adjustable relay The versatility of the AVT series air velocity transmitters ensures that the right product for your application is available. similar products applications • DPT-FLOW series air flow transmitters AVT series devices are commonly used in HVAC/R systems for: • in-duct air flow and velocity monitoring • in-duct temperature monitoring • VAV applications Copyright HK Instruments 2017 www.hkinstruments.fi Datasheet Version 6.0 2017
