ZTD-G digital displacer level transmitter
Consist: DLT9000head, measuring chamber, measuring mechanism, displacer, torque tube, etc.
Operation Principle: The liquid level difference caused the buoyancy of displacer change, then it will be transferred into the torque tube unit. The Hall-effect sensor senses the magnetic field change and converts the magnetic signals into current signals.
Application field: It can be used for measuring liquid level, interface and density.
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 ºC to +80 ºC (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
