Capacitive level gauge is a measuring instrument that uses changes in capacitance to measure the level of dielectric material inside a container. Inside the container, the walls made of electrodes and conductive materials form a capacitor. For a given electrode, when the dielectric constant of the measured medium remains constant and a fixed frequency measurement voltage is applied to the electrode, the current flowing through the capacitor depends on the height of the dielectric between the capacitor electrodes and is proportional to it.
1. Compact structure, small size, easy installation and maintenance, uniform external dimensions.
2. Multiple signal output forms facilitate different system configurations.
3. Polytetrafluoroethylene probe grade, resistant to strong corrosive liquids such as acid and alkali, and high temperatures.
4. The measuring part immersed in liquid only has one PTFE flexible wire or PTFE rod probe as a sensor, with high reliability.
5. Fully sealed aluminum alloy casing and stainless steel connectors.
6. Measuring high-temperature pressure vessels is as simple as measuring normal temperature and pressure, and the measured values are not affected by the temperature, specific gravity, container shape, or pressure of the measured liquid.
7. There are multiple circuit structure modes for measuring and outputting both ends, as well as measuring, outputting, and power supply three end isolators, with built-in isolators to adapt to different signal grounding methods.
8. Complete overcurrent, overvoltage, and power polarity protection.

To ensure measurement accuracy, the RF admittance level switch can be installed horizontally. If the measurement error is allowed within a few centimeters, it is recommended to tilt the equipment downwards by about 20 degrees before installation to avoid measurement errors caused by material accumulation on the probe (note: cable type RF admittance level switches are prohibited from being installed horizontally). For installation in some special application scenarios, protective barriers need to be added for the instrument to work more reliably (see Figure 1).
a. Common types of protective barriers
b. For baffle types with rough or highly abrasive materials
If the tested material level is rough or has high wear resistance, a concave protective baffle can be selected. This type of baffle can allow materials to form a certain accumulation in the groove, reduce the impact of materials on the baffle, and thus improve the service life of the protective baffle.
2. Vertical installation
When installed vertically, in order to avoid measurement errors caused by the angle of the intermediate material pile and the reactance of the container wall itself in cylindrical containers, it is recommended to install it at a distance greater than 500mm from the container wall (see Figure 2).
Please note that:
When selecting the installation position of the RF admittance level switch, it is necessary to avoid measurement errors and even damage to the instrument caused by installation at the feeding port position (see Figure 3).
