เครื่องส่งสัญญาณระดับความปลอดภัย ( อินเตอร์เฟซ ) (ATEX และ SIL2, PED )

Main performances and parameters
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 º C to +80 º C (when ≤ -30 º C, no LCD display. )
Operating temperature: -70 º Cto +400 º C
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 M20*1.5 (female) or as customers' request
