Differential Pressure Transmitter D31 – D-Series

HART Communication, aluminium or stainless steel enclosure

The D31 SMART Differential Pressure Transmitters are suitable for measuring differential pressure of gases, vapours and liquids. The active sensing element is a piezoresistive silicon sensor separated from the medium by a diaphragm and by a specially selected type of manometric liquid.  The special design of the active sensing element ensures that it is able to withstand pressure surges and overloads of up to 250/320/413 bar. The casing is made of cast aluminium alloy or 316 stainless steel with a IP66/IP67 rating. The design of the casing enables the use of a local display, rotation of the display by 90°, rotation of the casing by 0–355° relative to the sensor, and a choice of cable direction.

The D31 Differential Pressure Transmitter is suitable for measuring pressures from -100mbar to 70bar with maximum working pressures up to 413 bar.

Key Features
• Die cast weatherproof enclosure to IP66 (NEMA 4).
• Stainless steel mechanism.
• Internal tamperproof set point adjustment.
• Calibrated scale.
• Set point adjustment from -2.5mbar (-1 in H2O) up to 1.6 bar (20psi) dependent on model.
• ECAS Certified (Emirates Conformity Assessment Scheme)

 

Features & Benefits

  • Cost-Effective
    The D-Series offers customers a high specification and comprehensive product range at very competitive prices
  • Backlit LCD Display
    A backlit display facilitates local monitoring in light deficient environments by enhancing display visibility
  • Easily Configurable
    The D-Series transmitters are easily set up and configured either using a standard HART communicator or via Delta’s user-friendly ‘D-Soft’ communication software
  • Accuracy
    The D-Series transmitters have a standard accuracy of 0.075% with even better accuracy being available upon request
