Ürün tanıtımı

The airflow control system combines a duct averaging sensor, differential pressure transmitter, airflow controller and modulating damper actuator. The controller converts the measured velocity pressure into air volume using the configured duct area and continuously positions the damper. Low-flow cutoffs and sensor filtering prevent noisy readings from driving the actuator unnecessarily. The package can regulate supply, return or exhaust air and can share measured volume with the room pressure controller for coordinated cascade control.

Ana Özellikler

Averaging duct pickup samples multiple points instead of relying on one local velocity.

Configured duct dimensions convert pressure signal into a usable airflow-volume value.

Modulating actuator feedback confirms the commanded damper position was reached.

Filtering, deadband and low-flow handling stabilize control near minimum ventilation rates.

Müşteri Ürün Sorunları

Reliable air-volume control depends on representative sensing and an actuator response matched to the duct and pressure conditions.

A single-point duct reading changes with turbulence and elbow location.A multi-point averaging pickup provides a more representative velocity-pressure signal.

The damper hunts around the minimum airflow setpoint.Appropriate filtering, deadband and low-flow cutoff prevent reaction to measurement noise.

The displayed air volume is wrong after a duct size change.Field-configurable duct area and sensor coefficient recalculate volume for the installed branch.

A disconnected actuator is not noticed until room pressure drifts.Position feedback and airflow deviation alarms identify failed movement before the room leaves its normal band.
