Subsea Data Logger SDL Series

The SDL series subsea data logger is suitable for operation down to depths of 4000 metres, and can monitor up to 15 analogue, and 2 serial inputs from a wide range of sensors. The logger has an internal memory capacity of 5,000,000 readings, which can be expanded with a USB memory stick. The analogue input channels are user configurable to measure, voltage, mV, mA, resistance, frequency, T/C, PT100 and strain gauge inputs. The serial inputs support RS232, RS485, NMEA, SDI12, and ASCII text serial protocols.
