Series VTT Hot-Wire Air Velocity Transmitter, For Non-combustible Gases., Feature : Excellent Performance

Series VTT Hot-Wire Air Velocity Transmitter

Series VTT Hot-Wire Air Velocity/Temperature Transmitter

Configurable Air Velocity Ranges, Available with 5 Digit Display

The Series VTT Hot-Wire Air Velocity and Temperature Transmitter provides a versatile unit for air velocity and temperature needs. The VTT offers five field-selectable ranges as well as operating in metric (ms, °C) or English (fpm, °F) units. The VTT can measure up to 30 ms (6000 fpm) and 50°C (122°F). The units are available with or without an LCD display which alternates between velocity and temperature. Series VTT can be ordered in duct mount or remote mount configurations with 4-20 mA or 0-10 V outputs. The VTT is a useful transmitter for many common HVAC applications.
