Product description
Power supply | 12~30V DC; the controller has reverse polarity protection.(when HART is communicating, the voltage of controller ≥17.75V DC) |
Output signal | 4~20 mA DC (Positive direction – the increase of level, interface, or density make output increase; Negative direction – the increase of level, interface, or density make output decrease.) |
Measuring range | 300mm—2500mm (can also over range) |
Nominal pressure | ≤42.0MPa |
Nominal diameter | DN40 or as customers’ request |
Ambient temperature | -40 ºC to +80 ºC (when ≤–30ºC, no LCD display.) |
Operating temperature | -70ºC to +400ºC |
Measuring accuracy | 0.5% |
Influence from power supply | When the voltage of the power supply varies between min. and max. ,the output change is within <±0.2%. of the full scale. |
LCD display | Output current signal,process variable,process temperature,percentage range,rotation angle of torque tube. |
Medium density difference | ≥0.08g/cm³ |
Material of torque tube | Standard configuration Inconel 600,or Monel, HasetlloyC-276 |
Wetted material | 304,316L or as customers’ request |
Flange standard | HG/T20592-2009,HG/T20615-2009 or as customers’ request |
