SLS-D Digital submersible level transmitter – SDI-12

Discover the SLS Series Submersible Level Transmitters, designed for precise environmental monitoring and flood defence systems. Housed in a robust stainless steel casing, these transmitters feature an isolated diaphragm silicon piezo-resistive sensing element for utmost accuracy. Operating continuously in liquids up to 100m depth, they convert analog output to SDI-12 digital communications using the eco-friendly SDI-12 version 1.4 protocol, providing serial level and temperature readings. Our powerful SDI-12 communications software enables sensor calibration, density correction, and connection of up to 9 sensors, streamlining data logging and diagnostics. The onboard 16-bit microprocessor ensures exceptional accuracy and stability. Plus, with the USB interface (USB-SDI12-PRO), configuring and logging data for up to 10x SDI-12 devices becomes a breeze. Trust the SLS Series for unparalleled performance and peace of mind in challenging applications.
