    Pel-Dk - Differential Pressure Transmitter

    Uploaded by

    Kerim Jumanazarow
    The PEL-DK is a differential pressure transmitter for measuring pressure and pressure differences in air handling systems. It has temperature compensation and automatic zeroing to maintain accuracy. Users can select time constants of 2 or 8 seconds to dampen process disturbances. Models with displays or Modbus connectivity are available. The transmitter measures pressure ranges from 0-100 Pa to 0-1000 Pa with various accuracy levels depending on the range.

    PEL-DK - DIFFERENTIAL PRESSURE TRANSMITTER

    PEL-DK is a pressure transmitter for detecting


    pressures and pressure differences in air handling
    systems. The pressure measurement is temperature
    compensated according to the ambient temperature.
    The M models have RS-485 connection for
    Modbus RTU communication. ML-SER tool is needed
    at commissioning for making the Modbus settings.
    The transmitter zero point is kept accurate by using the
    regular automatic zeroing, eliminating the possible
    zero point drifting. No re-calibration is normally
    needed.
    The influence of process disturbances (e.g.
    turbulence) can be damped by selecting suitable time
    constant (2 s or 8 s).
    Technical data:
    The N models have a backlit display. The display Supply 24 Vac/dc (22...28 V), 2 VA
    resolution is 0,1 Pa for measured values below 200 Pa Measuring ranges 0...100 Pa ±50 Pa
    and 1 Pa for values over 200 Pa. The display can be
    0...200 Pa ±100 Pa
