Coaxial Capacitive Level Transmitter

The sensing part of the capacitive coaxial sheath type liquid level meter is a coaxial container. When the liquid enters the container, it causes the capacitance between the sensor housing and the sensing electrode to change. This change is converted by the circuit and accurately linearly and temperature compensated. It outputs a 4-20mA standard signal to the display instrument. This liquid level meter is suitable for measuring various non-conductive liquids and has strong anti-interference ability. In situations where the liquid level fluctuates greatly, this liquid level meter is an ideal choice.

Introduction of Coaxial Capacitive Level Transmitter

The capacitive coaxial sheathed level transmitter is a new generation of high-tech level meter independently developed by our company according to market demand. It can be used for liquid, oil, solid level measurement, without moving parts. It is not affected by water vapor, dust or condensation.

It has the advantages of stable and reliable operation, high sensitivity, good linearity, high temperature resistance, high pressure resistance, etc. The whole series of products has the function of on-site calibration, and users can perform automatic calibration of “zero point” and “range” by pressing buttons. It can adapt to the different requirements of various complex places. It can be widely used in various fields such as petroleum, chemical industry, metallurgy, electricity, papermaking, and pharmaceuticals.

Sino-Inst has other products that can measure liquid levels, you can refer to：Explosion-Proof Ultrasonic Level Meter,Submersible Stainless Steel Level Sensor,Float Level Sensors.

Advantages of Capacitive Coaxial Level Transmitter

Liquid level measurement of conductive media in pressurized containers (customizable)
Solids: fly ash, cement;
High-pressure containers: maximum working pressure: 32Mpa;
Working medium temperature: -70-250℃ (PTFE electrode optional)
Zero point, full scale, damping time, data recovery and other functions can be adjusted on site with three buttons; “Replacement of hand operator;
Liquid level detection is basically not affected by changes in process conditions. Buoyancy, differential pressure and isotope level transmitters are all related to the importance of the medium in detection. Changes in the gravity of gas and liquid phase media will cause additional errors in the detection results.
Wide range of adaptability: specially customized according to the specific characteristics of the detection object. It can adapt to liquid level detection under a variety of harsh conditions.
Lightweight installation: A high-pressure level transmitter working at 32MPa weighs less than two kilograms, which is a few tens of the weight of a high-pressure float level sensor.
