The Delta Pressure transmitter series of Johnson Controls, with its models SDP7000, SDP2500 and SDP2050, offers an accurate and cost-effective solution to monitor the pressure of the air, or nonaggressive gases, in the HVAC applications.
The DP series devices can measure pressure from -150 Pa up to 7000 Pa. For the best accuracy, each SDP 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 SDP 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 SDP series can be 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.
