Main technical parameter
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: –40ºC to +80ºC (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
Power entry: Two NPT 1/2 (female thread) or as customers'' request
Explosion-proof: Explosion isolation ExdⅡCT6, Intrinsically safe ExiaⅡCT6
Protection grade: IP66
Alarm jumper: For the self-diagnosis to the inaccuracy failure of the process variables (for example, the electronic module failure). Configure the process variables of high and low alarms.
