Levtron’s Capacitance Level Transmitter is designed for continuous level measurement of liquids, powders, slurries, and bulk solids in industrial tanks, silos, and process vessels. It provides accurate 4-20 mA output for reliable level monitoring and process control in automation systems.
The transmitter works by detecting capacitance changes between the sensing probe and the tank wall or surrounding medium. As the material level changes, the dielectric properties vary, allowing the device to measure the level continuously and accurately.
These transmitters are widely used in chemical plants, water treatment systems, cement industries, food processing units, and bulk material storage applications. Their durable construction and stable performance make them suitable for demanding industrial environments involving dust, moisture, pressure, and high temperatures.

Limitations: Insufficient ceiling clearance; non-conductive media with conductivity <100 μS/cm.
One of the key advantages of the Capacitance Level Transmitter is that it requires no calibration for media with a conductivity of 100μS/cm or higher. Additionally, it features corrosion-resistant materials, including FDA-listed components, ensuring durability and compliance with industry standards.
For ease of use, the device supports menu-guided local configuration via an optional plain-text display. The Capacitance Level Transmitter also incorporates a two-stage overvoltage protection system, enhancing operational reliability in challenging environments.
The Capacitance Level Transmitter functions based on the principle of capacitance measurement. It comprises a probe and a reference surface, such as a tank wall or another conductive element. As the material level (liquid or solid) fluctuates, the dielectric constant between the probe and the reference alters, leading to a change in capacitance.
When the material level increases, the dielectric constant rises, causing the Capacitance Level Transmitter to register a higher capacitance. Conversely, as the level decreases, the capacitance reduces. This variation is converted into an electrical signal, typically a 4-20 mA output, allowing precise monitoring and control.
The Capacitance Level Transmitter is capable of detecting liquid interfaces, including emulsion layers, making it highly versatile. Its advanced design ensures quick response times and reliable performance across different industries. The Capacitance Level Transmitter is ideal for challenging environments, offering durable and accurate level measurement solutions.
