Sound Velocity : SV Plus v2
Sound Velocity : SV Plus v2 : Description
Updated in mid-2004, the SV Plus was originally launched in 1996 and is the industry standard for sound velocity measurement. It is used extensively by such well known organizations as Kongsberg, Fugro, and multiple divisions of the U.S. and U.K. militaries. For the first time, a shortened real-time only version is available.
The instrument provides time-of-flight sound velocity measurements using invar rods. The SV Plus is a complete, ready-to-operate package, and includes an aluminum shipping case, 2m data / power pigtail, batteries, a sensor protection cage, a dummy plug, a maintenance kit, manuals and software.
In this configuration (see configuration number below), the updated SV Plus has no internal power, no memory, and no USB connector for data download. Other configurations exist with these features; please search our on-line product catalogue.
In the new version of the SV Plus, the pressure sensor accuracy has been improved from 0.15% to 0.05% and the sampling rate has been increased to 25Hz.
Upon request, Applied Microsystems hi-tech composite sound velocity sensor is now available on the SV Plus. This new approach to sound velocity sensor utilizes composite materials instead of stainless steel invar rods. Path-length change due to corrosion and vibration is eliminated, resulting in longer calibrations and less maintenance. Response to temperature change is immediate. Sensor range extends to 1600 m/s. On titanium or Delrin instruments, zincs are not required.
Like all Pluses, the SV Plus is designed for modularity. Upon request, as many as 8 other sensors can be added to the instrument in plug and play fashion. These same plug-and-play sensors are compatible with other Applied Microsystems Plus and Micro instruments.

Sound Velocity : SV Plus v2 : Usage Information:
| Int Description: | Plus - I - R/Time - 6061 | | Max Number Of Sensors: | 10 analog channels or 5 digital channels (NB: ability to integrate corresponding number of sensors a function of cumulative power requirements and available mounting / connector space) | | Depth Rating: | 5000 | Housing Material: | 6061-T6 Aluminium | | Weight Air: | n/a | | Weight Water: | n/a | | Length: | 338 (length of pressure housing from retainer ring / fender to sensor end cap) | | Diameter: | 100 | | Power Source : | External | | Housing Notes: | Dimensions and weight do not include any additional remote sensors that might be added to the configuration.
In this configuration of the Plus a USB connector is NOT included as the instrument does not contain memory.
The standard connector is a Subconn Micro 8 wet pluggable connector. Other connector choices can be accommodated, if desired. |

Calibrations are not extrapolated to cover the entire operating range of the instrument. This distinction is important. Instruments with extrapolated calibrations may find themselves significantly out of spec at individual sound velocity speeds, while the instrument - as a whole - meets averaged accuracy requirements. |
