Displacer Level (Interface) Transmitter--DDTOP

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.
