Overview

The RKL-04T Capacitive Liquid Level Transmitter operates on a coaxial capacitive sensing principle, where changes in liquid level alter the capacitance between electrodes. This variation is processed through signal conversion and temperature compensation circuits to provide precise and stable output signals such as current, voltage, or digital communication.

Built with food-grade Teflon and 304 stainless steel, the transmitter offers high mechanical strength, excellent hygiene standards, and strong resistance to corrosion. It is suitable for demanding environments, including chemical processing, fuel storage, water treatment, and medical applications. The device supports a wide measurement range from very low levels (as small as 0.03 m) up to 2 meters, making it especially effective for shallow tank measurements below 500 mm.

With features such as fast response, strong anti-interference capability, and wide temperature compensation, the RKL-04T ensures consistent performance even in harsh industrial conditions. Its flexible installation options and multiple output signals make it adaptable to various monitoring and automation systems.
