Overview

The RKL-01 Submersible Liquid Level Transmitter is engineered for accurate and long-term liquid level monitoring in demanding environments. It utilizes a high-quality diffusion silicon pressure sensor combined with a stainless steel isolation diaphragm to ensure precise measurement and durability. The internal sensing core is laser-trimmed, allowing effective temperature compensation and stable performance across a wide temperature range.

A specially designed vented cable enables atmospheric pressure compensation while maintaining waterproof integrity, ensuring consistent and accurate readings over time. The sensor is built with corrosion-resistant materials and offers excellent protection against moisture and environmental interference, making it suitable for submerged applications.

This transmitter supports multiple output signals including analog and digital formats, allowing easy integration with various monitoring and control systems. Its fast response time, high accuracy, and strong anti-interference capability make it a reliable solution for real-time liquid level measurement.

The RKL-01 is widely used in applications such as groundwater monitoring, reservoirs, wastewater treatment, rivers, irrigation systems, and industrial tanks. Its robust construction and IP68 rating ensure long service life even in challenging conditions, making it a dependable choice for environmental and industrial measurement tasks.
