Applied
Microsystems is pleased to announce that updated
versions of Applied Microsystems' CTD Plus oceanographic
instrument and SV Plus sound velocity profiler
will be commercially available by end-of-summer
of 2004. Major new features of this release include:
Share
Remote Sensors:
Any
remote sensor purchased for use with the new Plus
can be used with other Applied Microsystems Plus
or Micro instruments. For example, a dissolved
oxygen sensor originally purchased for vertical
profiling use with a CTD Plus can be easily connected
to an externally powered Micro CTD and deployed
on AUVs, ROVs, or other platforms.
USB
Data Download:
The
new Plus comes standard with USB download capability
to accelerate access to data once the instrument
has been removed from water. Access to the USB
port is via a removable threaded cap, which will
expose the USB connector. The USB connector itself
is located in a water-blocked header.
Choice
of Sound Velocity Sensor:
In the
new SV Plus, users can choose between our traditional
stainless-steel invar rod sound velocity sensor
or our high-performance, high-tech composite sound
velocity sensor. Prior to this release, the SV
Plus was compatible only with the invar rod sound
velocity sensor.
The high-tech composite sensor is built of fused,
non-metallic components with zero thermal expansion,
thus eliminating path-length change due to temperature
variation. Corrosion and vibration are also eliminated,
resulting in longer calibrations and lower maintenance.
Upgraded
Pressure Sensor:
Pressure
accuracies have been improved from 0.15%FS to
0.05%FS in the new SV Plus and the new CTD Plus.
For applications requiring even greater accuracy,
users can upgrade to a 0.01%FS DigiQuartz pressure
sensor.
Plug
and Play Remote Sensors:
In the
new Plus, remote sensors are no longer assigned
to specific connectors on the instrument end-cap.
Any analog (or digital or TTL) sensor can be plugged
into any analog (or digital or TTL) connector,
greatly simplifying field maintenance.
A number
of minor enhancements have also been introduced
to the updated Plus design. These include:
Baud rates on the new Plus have doubled, from
19200 38400 kb. Both baud rates and communications
protocols (RS232 / RS485) are software selectable
and no longer hard-coded into instrument firmware.
User selectable sampling rates are increased from
10Hz to 25Hz. Moreover, sampling rates are maintained
as significant numbers of additional remote sensors
are added. Previously, sampling rates diminished
substantially with the inclusion of additional
sensors.
The updated Plus is available in both Aluminum
and Delrin housings. The Delrin model has a depth
limit of 500m, but minimizes the need for zinc
anodes and their replacement. Delrin housings
are not available for vertical profiling applications.
Some conditions and limitations may apply. Contact
Applied Microsystems for full details on the new
Plus. Applied Microsystems will provide formal
notification when the new Plus is market available.
