Data logger takes direct sensor inputs

The Data Dolphin 128 (DD-128) data logger has an ultra-high-resolution, 24bit, A/D section that provides eight differential bipolar inputs with resolution down to 90nV.

The Data Dolphin 128 (DD-128) data logger has an ultra-high-resolution, 24bit, A/D section that provides eight differential bipolar inputs with resolution down to 90nV.

This allows most sensors to be directly connected without any signal conditioning.

An additional four inputs allow the user to select pulse, status or analogue capability.

All inputs have static protection.

Designed for use in applications such as pump station monitoring, strain gauge studies, meteorological studies and interconnecting weir monitoring, the DD-128 is encapsulated a waterproof case and offers reliable operation in temperatures ranging from -40 to +75C.

These units provide 1Mbyte nonvolatile Flash memory.

Three C-size alkaline batteries provide power, and an adapter input for 120V AC operation and an optional coin cell battery keep the clock operating when the battery pack is being exchanged.

An external 12V source, such as a rechargeable battery and/or solar panel, can be connected.

Data Dolphin software makes data collection and programming easy.

It allows the user to set up the program, view the data, generate graphs and export the data to other software for more detailed analysis and presentations.
