Diver-SDI

Diver-SDI is a SDI interface module for Diver Dataloggers.

Diver-SDSI can be used to connect Divers to remote monitoring systems using SDI protocols. It features a barometric sensor, which can be used to convert pressure values into water level.

A typical SDI-12 system is depicted in the figure below. In the schematic two Diver-SDI modules are connected to a SDI-12 recorder, via a 3-wire SDI-12 bus which also include the power supply of 12 Volt. On the other end a Diver cable (AS2xxx) is attached to connect the Diver-SDI to a Diver. Diver cables up to a length of 500 meter can be used with the Diver-SDI.

FEATURES

Features
• The Diver SDI module has a built-in pressure and temperature sensor for measuring real-time air temperature and atmospheric pressure.
• Automatic barometric compensation of the Diver pressure readings.
• Dynamic density compensation for accurate water levels in saline conditions when used in combination with the CTD-Diver.
• External power supply through SDI-12 system.

Benefits
• No need for additional sensors to measure air temperature and atmospheric pressure.
• No need for post-processing the pressure data.
• Accurate water levels when water density varies due to salt content.
• No internal battery is required.
• The compact Diver SDI module can be mounted inside the well casing for long-term, uninterrupted use.
