Summary
ZTD series displacer level transmitter is manufactured by FISHER and DDTOP. The core component is FISHER DLC***0 imported with original packaging, the rest parts are all made in China by DDTOP.
high pressure bouyancy level transducer
Operation principle
ZTD-G Smart Displacer Level (Interface) Transmitter consists of
DLT***0 level transmitter, measuring chamber, measuring mechanism,
displacer and torque tube, etc. The liquid level changing triggers
the change of the buoyancy of displacer, then it will be
transferred into the torque tube unit. This makes the torque tube
and core axle rotate synchronously. At the same time, the magnetic
steel parts that fixed at the core axle of the torque tube turn
rotary displacement. The Hall-effect sensor senses the magnetic
field change and converts the magnetic signals into current
signals. DLT***0 level transmitter uses micro-controller and
relatedelectronic circuit to measure process variable, supply
current output, drive LCD and support HART communication.
Micro-controller receives the electric
signals that have been temperature-compensated and linearised.
Meanwhile, compensates the liquid density change caused by the
change of the process temperature, then supplies 4~*0mA current
output signals. LCD can indicate analog output, process variables,
process temperature (if RTD is installed), degrees of the torque
tube rotation and percent range of variable, etc.
| Power supply | *2~*0V DC; the controller has reverse polarity protection.(when HART is communicating, the voltage of controller ≥*7.*5V DC) |
| Output signal | 4~*0 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 | **0mm—***0mm (can also over range) |
| Nominal pressure | ≤*2.0MPa |
| Nominal diameter | DN*0 or as customers’ request |
| Ambient temperature | **0 ºC to **0 ºC (when ≤–*0ºC, no LCD display.) |
| Operating temperature | **0ºC to ***0ºC |
| nfluence 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.*8g/cm³ |
| Material of torque tube | Standard configuration Inconel **0,or Monel, HasetlloyC***6 |
| Wetted material | **4,**6L or as customers’ request |
