Thru-Hull SVS

Cleaning and maintenance without docking, Thru-Hull Sound Velocity Sensor allows the probe to be deployed through the vessel’s hull and safely recovered.

It is particularly useful for multibeam applications where knowledge of the sound velocity adjacent to the multibeam transducer is necessary. The probe is also available with an optional PRT temperature sensor.

Technical Specifications

Sensors - Sound Velocity

Valeport’s unique digital time of flight sound velocity sensor. Advanced
composite, titanium and polycarbonate construction, together with the digital
sampling technique give unmatched levels of accuracy.

Range:
1375 - 1900 m/s
Accuracy:
±0.02 m/s
Resolution:
0.001 m/s

Temperature (optional)

Type:
Fast response PRT with guard
Range:
-5 to +35 °C
Accuracy:
±0.01 °C
Resolution:
0.002 °C

Valve

The Thru-Hull SVS uses a PN16 ball valve, nominal 100mm bore, operated
using a 90° turn lever. The valve is normally supplied in aluminium bronze, and
comes complete with full Germanischer Lloyds certification (or equivalent) to
allow it to be fitted to the vessel.

Data

Sampling:
Continuous Data at up to 8 Hz, data on demand, or Burst
Average mode
Protocol:
RS232, RS485 & RS422 fitted as standard
Baud Rate:
2400 - 115200 (8,1,N)
Format:
ASCII text in a selection of formats, including tab separated,
CSV or NMEA.

Power

Voltage:
9 - 30vDC
Power:
0.7W max

Operation

The valve should be fitted to the vessel in dry dock, and left in a closed position.
The mounting sleeve is fitted to the valve, and the SVS secured within the
sleeve. The SVS features O-ring seals to the sleeve, so once it is fitted, the valve
may be opened and the probe pushed into position.
To recover the probe, withdraw it into the sleeve, close the valve, and
disassemble the sleeve.
