Pengenalan Produk

The duct airflow measuring station uses several bead-in-glass thermal sensors distributed across the duct cross-section to capture a representative velocity traverse. Each node compares a heated element with a reference temperature element, and the remote transmitter combines the readings with the entered duct area to calculate volumetric or mass airflow. Stainless-steel probes, plenum-rated cables and an external display enclosure suit permanent installation where operators need more than a one-time balancing reading. Analog and network outputs can feed room-pressure control, air-change verification or maintenance trending.

Ciri-ciri Utama

Multiple independently calibrated sensing nodes reveal an uneven velocity profile that a single-point probe can miss.

Thermal-dispersion measurement operates at the low duct velocities common in ventilation and pressure-tracking branches.

A remote transmitter displays airflow and temperature while isolating electronics from the active duct section.

Selectable analog and serial communications support connection to airflow alarms or a building control system.

Kebimbangan Produk Pelanggan

Reliable airflow control depends on a measurement point that represents the whole duct profile and remains stable at low velocity.

An elbow or transition creates a skewed velocity profile across the measuring plane.A multi-node probe array averages velocities over the duct area instead of reporting one unrepresentative point.

Pitot-style pressure signals become too small for dependable low-flow tracking.Thermal-dispersion sensor nodes retain useful resolution at substantially lower air velocities.

A failed probe remains unnoticed while the control loop continues using a false total.Node-status diagnostics and configurable alarms identify sensor or transmitter faults for maintenance.

Temporary balance readings do not show later drift caused by filter or fan changes.Permanent measurement provides continuous total airflow and a recordable signal for trend comparison.
