displacer level switch
Displacer level transmitter is composed of level controller and measuring chamber, displacer, torque tube and
other components. The change of the measured medium level causes the buoyancy of the float to change,
and the change is transmitted to the torsion tube component, which makes the torsion tube rotate one angle
with the mandrel synchronously. A sensing system coupled to the torsion tube mandrel generates a voltage
signal. The level controller electronic assembly measures the level (interface) signal and provides a 4 to 20 mA
current output. The microcontroller measures the ambient temperature to compensate for changes in liquid
density caused by changes in process temperature, and the LCD displays information such as the analog
output, process variables, process temperature (RTD installation required), torsion tube rotation angle, and
percentage range of the level (interface).

Technical Parameters
Power supply: 12~30V DC; with reverse-polarity protection. (When HART communication is used, the
voltage of controller should be larger or equal to 17.75V DC）
Output: 4～20mA DC+HART (Positive effect - increased output due to increased level, interface or density;
or negative effect - decreased output due to increased level, interface or density)
Range: 300mm - 2500mm (to order; customized design if out of range)
Nominal pressure: ≤42.0MPa(Class2500)
Nominal diameter: DN40 or to order
Ambient temperature: -40 ºC to +80 ºC (When ≤ -20 °C, LCD no display, remote transmission can be
used normally.)
Medium temperature:－196°C≤T≤+450°C
Accuracy: 0.5
Influence by power supply: When the voltage of the power supply varies between min. and max. ,the output
change is within ＜±0.2% of the output range.
LCD display: Output current signal, process variable, process temperature, percentage range, rotation angle
of torque tube.
