HK Instruments AVT is an electronic air velocity and temperature transmitter for air and non-combustible gases with optional relay output AVT series air velocity transmitters are engineered for building automation in the HVAC/R industry. The AVT measures 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. The collar allows incremental adjustments to the insertion depth, enabling fine-tuning of measurement results to conform test and balance data. AVT series devices include: • Three (3) field selectable measurement ranges for air velocity, selectable via jumper, see Model Summary. • Separate readings and outputs for air velocity and temperature. • Output options include: voltage (0–10 V) and current (4–20 mA). AVT series device offers: • LCD display • Field adjustable relay • NIST-calibration documentation. The versatility of the AVT series air velocity and temperature transmitters delivers the right product for your automation application.
