Microstructure Probe MSS 60

The MSS60 is a multiparameter probe for measuring micro-scale water stratification as well as the intensity of small scale turbulence in water down to approx. 500 m, preferably in coastal water, rivers and lakes. The MSS60 profiler may be equipped with up to 5 different sensors (7 different parameters) mounted at the bottom cap.

The microstructure measuring system comprises the MSS profiler, a special winch, a probe interface and a data acquisition computer. The probe interface is adapted to the PC (laptop or desktop) via USB port.

Standard sensor equipment:

  • Pressure transducer
  • Temperature (PT100)*
  • Conductivity
  • 2 x Shear
  • Fast temperature sensor (NTC)
  • Acceleration (vibrations) – intern

* combined temperature and conductivity sensor

Microstructure investigation requires an undisturbed measuring procedure of the profiling instrument. Effects caused by cable tension (vibrations) and the ship’s movement have to be excluded by buoyancy driven free sinking of the MSS Profiler. This requires a slack in the cable near to the profiler. The loop in the cable is generated and kept during the profiling by immersing sufficient cable into the water. For vertical sinking measurements, the profiler has to be balanced with a slightly negative buoyancy which gives it a sinking velocity in the range between 0.3 to 0.7 m/sec.

The profiler can be manually handled and recovered. For more convenient operation, a special portable winch can be used. The data are transmitted via electrical cable to a board unit and further to a data acquisition PC. The on board unit comprises the power supply for the profiler and the receiver of the data link. The data are stored on the hard disc of the acquisition PC during the measuring process.

The basic hardware system for microstructure field measurements consists of 4 parts

  • microstructure profiler
  • USB-Interface and power supply
  • sea cable connection between interface and profiler
  • PC, Laptop or Notebook with USB interface

The measuring system can be powered either by mains (230VAC or 115VAC, standard version) or battery (12 VDC, option).
For data acquisition the high speed Micro-Structure Data Acquisition program MSDA is used. MSDA displays the received data and stores it on hard disk. Graphical functions enable a convenient operation of the system.

The sea cable has an almost neutral buoyancy and can carry weights of more than 50 kg. If the
system is ordered without a winch, a cable drum with slip rings is provided for the transport of the
sea cable. The cable is fitted with the proper underwater inline connector SUBCONN MCIL5F,
locking sleeve SUBCONN MCDLSF and on the ship side with a LEMO 4-pole round connector.
The cable drum is not intended to be used as hand winch, cable handling has to be made
manually.

For more convenient operation, a special portable winch can be used. The data are transmitted
via electrical cable to a board unit and further to a data acquisition PC. The on board unit
comprises the power supply for the profiler and the receiver of the data link. The data are stored
on the hard disc of the acquisition PC during the measuring process.
