Level Transmitter

Capacitance / Admittance Level Transmitter Type : RCLT

Feature

Simple structure: There are no movable or elastic components, so the reliability is extremely high and the maintenance is minimal. Under normal circumstances, it is not necessary to perform maintenance.
Easy to install: Install directly on site, no special tools are needed, and it can be installed in 10 minutes.
Easy adjustment: The two potentiometers of zero position and range can perform zero adjust or decrease/increase range arbitrarily within the effective range of liquid level detection. The adjustment of zero position and range does not affect each other.
Wide range of applications: suitable for liquid level measurement of high pressure, strong corrosion and other media.

The Capacitance / Admittance Level Transmitter Type RCLT is an industrial continuous level measurement instrument designed to accurately measure liquid levels inside tanks, vessels, and process equipment. It utilizes Capacitance / RF Admittance technology to detect changes in capacitance between the sensor probe and the tank wall, converting the measured level into a standard 4–20 mA analog output for integration with PLC, DCS, and SCADA systems.

Unlike level switches that only provide ON/OFF signals, the RCLT continuously monitors the liquid level, making it ideal for process control, inventory management, and industrial automation.

With no moving mechanical parts, the transmitter provides excellent long-term reliability, minimal maintenance, and stable performance under high-pressure, high-temperature, and corrosive process conditions. It is widely used in oil & gas, chemical processing, water treatment, food & beverage, pharmaceutical, power generation, and various industrial process applications.
