Product Introduction

A 900 x 900 mm station distributes sensing points across a 0.81 m² nominal section. The transducer output supports airflow calculation for main-duct trending, ventilation alarms or a separate fan-control loop.

Key Features

Large sensing grid spans high-volume trunk geometry.
Measurement assembly remains independent of the regulating damper.

Pick-Ups	Distributed averaging array
Pressure Comparison	Total versus static
Electrical Output	0 to 10 VDC
Output Basis	Differential-pressure signal
Controller Function	Airflow conversion and monitoring
Application	Main rectangular ducts
Customization	Available for the required trunk geometry and operating environment.

Applications

Main outside-air volume monitoring
Large return-air trunk supervision

Solutions for Your Application

A large trunk needs measurement across more than one local stream.

Distributed pressure pick-ups sample the broad airway before the combined signal reaches the transducer.

Available Options

VFD control integration
Under-ventilation alarm output through controller
