Velocity Sensor Control

Overview: An ultra-sensitive air velocity sensor and pneumatic controller, control pneumatic damper actuators in heating and air conditioning systems to provide constant air velocity in the duct regardless of the static pressure. Features: State-of-the-art design provides reliable operation. Not position sensitive. Direct Acting (DA) and Reverse Acting (RA) models are available. Insensitive to static pressure changes. Accurate control throughout entire velocity range. Graduated scales for minimum and maximum velocity adjustments. Velocity reset by thermostat demand. Adaptable to many terminal unit control strategies.
