The capacitive level transmitter represents an extension and development of pressure transmitter technology. Based on the principle that the pressure generated by liquids of different specific gravities at different heights is linear, it enables accurate measurement and transmission of the volume, liquid level, and weight of water, oil, and paste-like substances. It not only features simple installation and easy use as well as strong interchangeability, but also offers an innovative display with intuitive and prominent readings; moreover, the orientation of the indicator can be adjusted according to the user’s needs. It has a large measurement range and is not restricted by the tank height. Capacitive level transmitters effectively eliminate the influence of factors such as temperature, humidity, pressure, and the electrical conductivity of substances on the measurement process, thereby offering extremely high resistance to interference and reliability. It can measure highly corrosive liquids such as acids, bases, salts, and sewage. Capable of measuring high-temperature, high-pressure media ； Process temperature: -40～600℃ ； Process pressure: -0.1 to 4.0 MPa. Some intelligent integrated capacitive level gauges feature a unique two-point on-site calibration technique, which facilitates easy use of the product by users. Its probe and transmitter are separate components, and the shielded cable connecting them can be up to 1 kilometer long; it can be installed in extremely harsh environments, making it particularly suitable for applications involving high temperatures, vibration, corrosion, hazardous conditions, or situations where remote setting is required. Capacitive level transmitters can convert changes in various level parameters into standard current signals, which are transmitted to the operation control room for centralized display, alarm generation, or automatic control by secondary instruments or computers. Thanks to its excellent structure and installation method, it is suitable for the continuous monitoring of liquid level, material level, or substance level under special conditions such as high temperature, high pressure, severe corrosion, tendency to crystallization, the need to prevent blockages and freezing, as well as in situations involving solid powdery or granular materials. It can be widely used for monitoring and control in various industrial processes. Capacitive level transmitters are standard two-wire or three-wire instruments; the power (signal) terminals are located on the wiring side inside the instrument housing. The signal wires should be shielded wires or twisted pairs of wires tied together. They should not be run through conduit or exposed cable trays alongside other power wires, nor should they pass near high-power equipment.
