DPT-Ctrl Flow Meter Series Datasheet

DPT-Ctrl - Differential pressure or airflow controller

Description: The DPT-Ctrl differential pressure or airflow controllers are engineered for building automation systems, offering precise control over constant pressure or airflow in fans, VAV systems, or dampers. These controllers can be configured to control differential pressure or airflow across ducts or centrifugal fans, providing versatile solutions for HVAC applications. The user-friendly interface allows for easy setup and adjustment of settings according to specific requirements.

Key Features and Selectable Functions:

• PID controller for controlling differential pressure or airflow
• Measurement and monitoring of differential pressure or airflow
• Multiple selectable measurement units
• Voltage or current output options
• Optional automatic zeroing function (-AZ models)

With the automatic zeroing function (-AZ models), the transmitter zero point remains accurate by automatically compensating for any potential zero point drift, minimizing the need for recalibration.
