KSLV605 Capacitive Level Transmitter – Oil Tank Truck Measurement, without display

Capacitive level transmitter

Capacitive intelligent liquid level sensor is a liquid level (material level) transmitter that can be used for liquid, oil, solid, interface and measurement. There are no moving parts, the reliability is greatly improved, it is not affected by water vapor, dust or condensation, and has the advantages of stable and reliable long-term operation, high sensitivity, good linearity, high temperature resistance, high pressure resistance, etc. The intelligent liquid level meter is a two-wire (loop powered) 4~20mA DC measurement signal, easy to adjust, wireless transmission, 485 transmission, etc. Can be widely used in petroleum, chemical, metallurgy, electric power, paper, pharmaceutical and other fields.

Capacitive level transmitter Structure

Capacitive liquid level sensors have different structures due to different application occasions and parameters, but in general, its main structure can be roughly divided into two parts, namely the sensor part and the transmitter part. as the picture shows:

A in the picture shows the sensor, which directly probes into the container equipment or measures
in the measured medium of the meter tube

B and C in the figure are the gas phase and liquid phase connection flanges of the liquid level measurement and control instrument, which are used for the connection of the equipment flanges, and the liquid and pressure in the equipment are drawn to the measuring cylinder.

D in the figure shows the measuring cylinder of the liquid level measurement and control instrument, which can form a capacitance with the sensor electrode.

E shown in the figure is the sewage flange, which can regularly discharge the dirt in the liquid level measurement and control instrument to the outside, keep the inside of the measuring tube of the liquid level measurement and control instrument clean, and prevent the sensor from adhering to the dirt.

F shown in the figure is the Capacitive level transmitter, which is a conversion device from capacitance to standard current signal, and is the central part of the entire liquid level measurement and control instrument. Its main function is to receive the capacitance change increment caused by the liquid level change sent by the sensor, and then After conversion, it outputs 4-20mADC standard current signal. This transmitter adopts military integrated devices, with low power consumption, high temperature resistance, strong reliability, and meets the requirements of intrinsic safety.

Note: There is a sealing part between the transmitter and the measuring tube, which is composed of several seals, which can ensure that the measured medium is in contact with the sensor but will not leak out, causing harm. This section is an important sealing part, please do not disassemble it without the consent of the manufacturer to avoid accidents.
