SLS-A Submersible level transmitter – Analogue Output

Discover the SLS Series Submersible Level Transmitters – cutting-edge devices designed for precise liquid level measurement. Encased in a durable stainless steel housing, these transmitters feature an isolated diaphragm silicon piezo-resistive sensing element, providing a permanent submersible capability in liquids up to 100m deep. Choose between a raw millivolt output for low-power applications or an integrated microprocessor option offering amplified outputs like 4-20mA, 0-10V, or 0.5 to 4.5V ratiometric signals. The onboard 16-bit microprocessor ensures exceptional linearisation, temperature compensation, and calibration, delivering unmatched accuracy, stability, and repeatability. Ideal for environmental monitoring, flood defense systems, and river, reservoir, or borehole measurements. Empower your applications with the precision and reliability of the SLS series.
