Product Description

Capacitive level measurement principle:

probe line and conductive liquid constituted a capacitor, among them probe line metal inner core is one pole of capacitor the other pole is conductive liquid, the material between them is high stability PPR or gather fluorine ethylene.
The probe line  insulators outer as media of capacitor poles, surrounded area by liquid change along with the change of the liquid level, so that make relative area of capacitor polar changed which leading to the change of capacitance. According to the capacitance formula we can find out the relationship between liquid height and capacitance.

Performance parameters:

• Power: DC 5V,12 V,9~28 V
• Displacement range: 100 to 2000 mm
• The output signal: 0-5 VDC , 4-20 mA etc.
• Digital RS485 output (MODBUS RTU) (9-28 V DC power supply voltage)
• Linear error: analog output: ±0.1%F.S.
• Working temperature:-20 ℃-+ 85 ℃

Application:

1,tanker, automobile fuel tank
2, the steel industry
3, metallurgical industry
4, oil field, chemical industry
5, the conductive liquid measurement

Capacitive level sensor has auto-calibration function, the user can carry through zero or range automatic calibration through the two buttons or two lead lines, can adapt to the different requirements of various complex place. Product core parts adopt international advanced highly integrated special IC chip. Mainly manufacture capacitance level sensor--
