Subsea Technologies for the marine environment
MicroDI™ - Subsea Datalogger
Ultra-low-power
Long deployments
Full ocean depth
Very high accuracy data acquisition
Extreme high data storage capacity
Customized designs to your need
Fail-safe operation
Titanium for harsh conditions
The MicroDI™ (Micro Data Interface) Datalogger is designed special for
rough
and high-accuracy measuring applications. The main features are: ultra low-power for long-time
deployments, multiple high accuracy analogue inputs, high precision real-time and high data storage
capacity. Serial inputs, configured as RS-232 or RS-485 interfaces, can be used for digital sensor
signals and online real-time data output. The micro-SD Card can be used on a standard PC to readout
the data from many years. With a high analogue data sampling rate of up to 10 Hz not only longtime monitoring applications can be supplied, but also e.g. wave sampling. The ultra low-power
consumption design allows condition or long-time monitoring. The modular hardware and flexible
software design enables sufficient solutions for many different challenging applications. With the
optionally internal Li-Ion rechargeable battery a complete autonomous measuring system is realized.
De/Mobilisation is easy by using magnetic switch, checking the LED control light or setting up the
configuration by ASCII commands.
