New from Scientific Technologies Automation Products Group is the Data Dolphin 220 data monitor.

New from Scientific Technologies Automation Products Group is the Data Dolphin 220 data monitor.

The new units have an ultra-high-resolution 24bit analogue-to-digital section to provide four differential bipolar inputs with resolution down to 90nV, which allows most sensors to connect directly without any signal conditioning.

Four additional inputs allow the user to select pulse, status, event start/stop or analogue capability.

An operating range from -40 to +60C makes the DD-220 an excellent choice for field use in applications such as pump station monitoring, strain gauge studies, meteorological studies, interconnecting weir monitoring and wireless data-monitoring and alarming.

All inputs have static protection.

An adapter input allows for 120 VAC operation, while three internal C size alkaline batteries provide backup to keep the clock operating during a power interruption.

An external 12V source such as a rechargeable battery and/or solar panel can be connected for backup power for external sensors and remote telemetry applications.

A wide choice of telemetry options including GPRS cellular, spread spectrum and Wi-Fi are also available to provide a highly flexible data acquisition/monitoring solution.

The DD-220 stores data in a nonvolatile, long-term Flash, removable 1Mbyte memory module to eliminate fear of data loss from dead batteries.

As data remain inside a database structure, inputs may be added or deleted easily without restarting the data monitor.

The sample rate also may be changed without restarting.

Data Dolphin software makes data collection and programming easy.

It allows the user to view the current data, set up the monitor, generate graphs and export the data to another system for more detailed analysis and presentations.
