Standard export package

China single flange differential pressure transmitter

Technical parameter: 

1Output:
  Analog : Two-wire 4 ~ 20mADC
  Digital: two-wire 4 ~ 20mADC and superimposed HART protocol process variable digital signals.
2 Power: 12.5 ~ 45VDC supply voltage
3 Load Limit: Maximum load resistance Rmax loop depends on the supply voltage . HART Communication requires a load resistance of not less than 250Ω, not more than 600Ω
4 Communication distance: maximum communication distance of 1.5Km, multi- station communication can connect up to 15 units of smart transmitters .
5 Output Display: four digital display system , five LCD display, pointer .
6 Proof in the form :
  Intrinsically Safe : ExiaII CT5
  Flameproof
7 Zero migration range: zero can easily migrate positive or negative migration, but not so set on the lower measuring range and range beyond the limit.
8 Temperature range: Ambient temperature : -40 ~ 85 °C ( optional LCD instruction table is -20 ~ 70 °C)
9 Measuring medium temperature : -40 ~ 104 °C
10 Remote device fill fluid ( temperature ) :
  Visco : -29 ~ +149 °C
  Inert oil : -18 ~ +204 °C

Performance indicators:
Under no migration , capillary length 1.53m filling oil, 316 stainless steel diaphragm conditions : reference conditions
Temperature effects: remote device ( typically ) one side ( capillary remote 1.53m table remote device )
Flat : error of less than 0.62Kpa/55 °C, using silicone capillary filling each additional 1.53 m error increases 0.20Kpa
Threaded and flange type : error of less than 1.99Kpa/55 °C, using silicone capillary filling error increases for each additional 1.53 m 0.62 Kpa
Vibration: can withstand any axial vibration frequencies up to 200Hz , the error is ± 0.05% URL
Power effect: less than 0.005% of the tone scale / V
Load Impact: No load impact
Mounting Position Effect : 250Pa roughly zero migration , which can be calibrated , no scale effect .
RF interference effect: at a frequency of 30-1000MHz and maximum field strength 10V / m conditions caused by the drift of ± 0.1% of span adjustment
