Differential Pressure Transmitter

Differential Pressure Transmitter

DPT 2015 Series

The DPT-2015 Differential Pressure Transmitter senses differential pressure in pressure independent Variable Air Volume (VAV) applications. It sends an analog signal that is proportional to velocity pressure to a VAV controller. The DPT-2015 is available mounted to an M9104 or M9106 Electric Non-spring Return Actuator or to the Johnson Controls VAV controller for reliable damper positioning in closed-loop applications.

The DPT-2015 may also be mounted alone as an independent pressure transmitter or used for damper positioning in other VAV systems. The DPT-2015 is connected to the VAV box airflow pickups and measures differential pressure and generates a proportional voltage signal. The voltage signal from the DPT-2015 is read by the VAV controller and converted to airflow in cubic feet per minute (cfm). Calibration is not required other than zero calibration, which is performed within the controller.

Features and Benefits
  • Integral pressure transmitter with dead ended input ports eliminates an inline filter and maintenance; prevents sensor contamination
  • 0 to 1.5 in. Water Column (WC) Input Pressure Range satisfies requirements for virtually all terminal box applications
  • .5 to 4.5 in. Water Column (WC) Input Pressure Range provides compatibility with wide range of Heating, Ventilation, Air Conditioning (HVAC) controllers
  • No warmup period allows for immediate commissioning after power-up
  • Capacitive sensor technology for long-term stability and accuracy
  • 4 VDC output span replaces DPT-200-2 when used as recommended
