DLT(displacer level transmitter) performances and technical parameters1.Power supply: 12 to 30 volts DC; the controller has reverse polarity protection.2.Reference accuracy: 0.5%; 1%.3.Input signals: For Level, Interface or Density, the angular shift of the torque tube core axle is in direct proportional to the changes of liquid level, interface level, or density.4.Temperature: Temperature detector can compensate density change caused by temperature change.5.Output signal: Analog: 4 to 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.)Digital: HART 1200 Baud FSK (frequency shift keyed)6.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.7.Influence from temperature: Within 40 to 80 , the general influence from the temperature to the zero level and full scale level is less than 0.03% of the full scale for per absolute temperature degree change when the transmitter has no measuring cage with it. 8.Alarm jumper: For the self-diagnosis to the inaccuracy failure of the process variables (for example, the electronic module failure), the high and low alarms for the configurable variables depend on the alarm jumper position (in the workshop, the alarm jumper is set at high level). 9.LCD meter indications: LCD meter indicates analog output, and also can display process variables, process temperature, percentage or the angular shift of the torch tube. 10.Protection grade: IP6611.Min. density or density difference: ≥0.08g/cm³ 12.Power entry: Two 1/2-14 NPT
