MSL Subsea Data Logger

Quick Overview

The MSL subsea data logger is suitable for operation down to depths of 4000 metres, and can monitor up to 10 analogue and 1 serial input, plus integral 3-axis acceleration and light sensor. The logger has an internal memory capacity of 1,500,000 readings, which can be expanded with an SD memory card to over 40 million readings.The analogue input channels are user configurable to measure, voltage, or frequency. Seven of the ten analogue inputs can be configured to read frequency signals from flow meters. The serial input supports RS485 Modbus protocol which can be used to read pressure and temperature data from up to 8 of our subsea pressure sensors.

  • Subsea data logger for pressure, flow, temperature etc.
  • Integral sensors for x, y, z acceleration and light
  • 10 analogue inputs channels (0-5vDC)
  • Supports voltage, mA and frequency inputs
  • Up to 7 analogue inputs can be set for flow meter frequency inputs
  • 1 serial channel for RS485 Modbus protocol
  • Serial channel supports up to 8 Keller subsea pressure sensors
  • Pressure measurement to 1360 bar, with accuracy to 0.01% FSD
  • Flow measurement 0-5 to 0-10,000 Ltrs/min accuracy 0.5% FSD
  • Optional integral high contrast backlit LCD display
  • Optional external subsea dual display unitSubsea Flow Meter
  • Internal memory 1.5 million readings
  • Micro SD card holds an additional 100 million readings
  • Depth rated to 4000 metres
  • Optional external power supply 11-30vDC
  • Power consumption 8mA with display on, 5mA with display off
  • Internal battery option provides minimum one month operation without external power
  • Increased battery capacity for longer operational periods available
  • Surface programming and data transfer by standard wired USB cable.

The MSL subsea data logger can be configured to measure a wide range of parameters such as pressure, flow, continuity etc. It is compatible with most sensor analogue outputs and also standard serial protocols. It is also compatible with Keller subsea pressure sensors (both analogue and serial outputs) and NT Series subsea turbine flow meters. For more information on compatible pressure and flow sensors click here.

The logger can hold 1.5 million readings in it's internal flash memory and a further 100 million readings on a micro SD card. Two communications options are available:

RS232 communications for logger programming and data download from the flash memory (1.5 million readings)

USB communications for logger programming and data download from the flash memory (1.5 million readings)

An external subsea display can be added which is capable of displaying 5 channels at one time and 20 channels in total.
