DP Transmitters

The Delta Pressure transmitter series of Johnson Controls,
with its models DP7000, DP2500 and DP2050, offers
an accurate and cost-effective solution to monitor the
pressure of the air, or non-aggressive gases, in the HVAC
applications.
The DP series devices can measure pressure from -150
Pa up to 7000 Pa. For the best accuracy, each DP device
has field selectable pressure setting within its full range.
The pressure measured by the device, either in differential
or static mode, can be transmitted to the HVAC controller
through a proportional output signal.
A number of options make Commissioning and Servicing
flexible and easy. Each DP model includes:
• Eight field selectable measurement range settings
• Optional display, with field selectable units
• Two Proportional output signals, in voltage (0–10 V) or
current (4–20 mA).
• Zero calibration, manual or automatic
• Response time setting
The low pressure DP0250 can be field calibrated, all other models, on request, can be provided with a Factory Calibration
Certificate.
The DP transmitters are typically used in HVAC applications to control: fan, blower, dampers, filter condition, monitoring
air flow in the distribution system and pressure in cleanrooms.
