详细介绍:

  SATRON VDU differential pressure transmitter belongs to V-series transmitters.  SATRON VDU differential pressure transmitter is 2-W transmitter and  is used from 0-1.4 kPa to 0-3 MPa ranges. In pressure measuring applications, SATRON VDU diff.pressure transmitters are used for measuring the pressure of clean, sedimenting, crystallizing and sticking materials.The transmitter's sensor is piezoresistive. The rangeability  is 25:1. The transmitter communicates digitally using the HART® protocol.

TECHNICAL SPECIFICATIONS
Measuring range and span See Selection Chart.
Zero and Span adjustment
Zero elevation: Calibrated span is freely selectable on the specified range.  This can be made by using keyboard  or HART®275 communicator.
Damping - Time constant is continuously adjustable 0,01 to 60 s.
Temperature limits Ambient: -30 to +80 °C
Process: -30 to +125/+200 °C
Shipping and storage: -40 to +80 °C.
Operating temperature of display: 0 to +50ºC (does not affect operation of the transmitter)
Pressure limits Min. and max. process pressure: See the appended tables.
Volumetric displacement < 0.5 mm3  /max. span (in both sensors)
Output 2-wire (2W), 4-20 mA,
Supply voltage and permissible load See the load capacity diagram;
 4-20 mA output: 12 - 35 VDC.
Humidity limits:0-100 % RH; freezing of condensed water not allowed in reference pressure channels.
PERFORMANCE SPECIFICATIONS
Tested in accordance with IEC 60770: Reference conditions, specified span, no range elevation, horizontal mounting; AISI316L diaphragm, silicone oil fill.
Accuracy
 ±0.2 % of calibrated span (span 1:1-7.5:1 /max.range). On the measuring ranges 7.5:1-25:1:
Long-term stability ±0.2 % / max. span / year
Temperature effect:- on -20 to +80 °C range
 Zero and span error: ±0.3 % of max. span. - on 0 °C to +200 °C range (process temperature code H)
  ±2 % of max. span, VDU6
  ±4 % of max. span, VDU4, VDU5
Temperature effect:- on +20 °C to +70 °C,
process connections  BA and DA
Zero and span error: ±0.15 % of max.span, code S
Mounting position effect Zero error < 0.32 kPa, which can be calibrated out.
Vibration  effect (IEC 68-2-6: FC): ±0.1 % of measuring range/
   2g/10 to 2000 Hz
   4g/10 to 100 Hz
Power supply  effect < ±0.01 of calibrated span per volt
Insulation test voltage 500 V rms 50 Hz
