Van Essen AS379 Diver-SDI SDI-12 Interface for Diver ABS IP65

The Diver-SDI integrates Divers with SDI-12 remote monitoring systems. A typical SDI-12 system is illustrated in the figure below. On one end the Diver-SDI is connected to the SDI-12 system through the 3-wire SDI-12 bus, which also includes 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 meters (1,640 ft.) can be used with the Diver-SDI.

Features:

• The Diver-SDI 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 can be mounted inside the well casing for long-term, uninterrupted use.

Applications:

• Real-time monitoring of municipal water supplies
• Saltwater intrusion monitoring
• Monitoring water quality and quantity at mine sites
• Monitoring water level and salinity of reclaimed water
• Groundwater monitoring networks
