Intelligent Conductivity/Temperature/Pressure Sensor
Intelligent Features and Data Acquisition
Intelligent Conductivity/Temperature/Pressure Sensor model CP300 is
a complete, self-contained conductivity, pressure and temperature measurement
and data logging system. The CP300 provides sophisticated and versatile
data acquisition, control and communications capabilities. Standard features
of the CP300 include:
-
Storage of measured data within the sensor for long periods.
-
Easy configuration of logging parameters and uploading of logged data.
-
Automatic transfer of data to a central office simply by attaching a
data modem and mobile phone.
-
Improved linearity and accuracy through the use of microprocessor based
compensation.
-
Facility to set alarm conditions which can trigger additional monitoring
equipment such as water samplers.
-
Lithium battery pack option for fully self contained operation.
A separate data logger and weatherproof housing are not required, eliminating
the added deployment costs normally associated with providing a remote
data logging capability.
Sophisticated communication features in the CP300 make remote site
logging of key water parameters easier than ever. In combination with an
external data modem and mobile phone, the CP300 enables remote uploading
of logged data and re-programming of logging schedules. In addition the
CP300 can respond to user-programmed alarm conditions by triggering an
associated sensor or by calling one of four preset phone numbers with a
user-programmed alarm message.
The CP300 can be powered using external batteries (via the sensor
cable) or with optional lithium battery pack, which can be fitted as an
extension to the sensor body, making a fully self-contained measurement
and logging system.
The CP300 also provides a supplementary rain-gauge input. With the
addition of a tipping bucket raingauge, the CP300 becomes a completely
self-contained hydrographic measuring station, enabling correlation of
rainfall and river height data from one compact monitoring package.
MODEL CP300
State of the art ceramic pressure and toroidal conductivity measurement
technologies guarantees long term performance and highly accurate temperature
compensated measurements in the harshest of environments.
The CTD provides numerous state of the art features:
-
Toroidal conductivity sensing technology eliminates electrode corrosion
effects, guaranteeing long life and reduced field service.
-
On-board microprocessor controlled temperature compensation and linearisation
delivers accurate conductivity data normalised to 25 C. Alternatively,
raw conductivity data is also provided.
-
Ceramic pressure sensing diaphragm offers unmatched reliability.
-
Depth readings regardless of atmospheric pressure changes (through the
use of a large diameter venting tube cable).
-
Software calibration allows users to quickly and accurately recalibrate
the sensor, eliminating the down time required when sensors have to be
returned for laboratory calibration. Easy to use calibration software runs
on a portable PC.
Reliability
The CP300 Sensor combines robust, sealed construction with an electrode-less
conductivity sensing system to offer unparalleled reliability. Designed
for low power consumption, the sensor can be operated from remote power
sources for extended periods. The high reliability of sensors means critical
measurements are not lost through sensor down time. Time wasting unscheduled
site visits are therefore minimised.
Accuracy
The CTD substantially eliminates inaccuracy in conductivity measurements
due to temperature and electrode effects. A large toroidal sensing element
uses free ions in solution as a conductive path between two shielded ferrite
transformer cores, eliminating errors caused by electrode degradation.
On-board microprocessor compensation substantially reduces system non-linearity
and temperature drift errors.
Accuracy in pressure measurement is designed into the CTD through
the use of a large-faced gold plated ceramic pressure sensor Ñ a
technology known for its long term repeatability Ñ supplemented
by microprocessor controlled electronics which maintain near perfect linearity
(0.02%) and low temperature drift (0.002%/¡C) over a wide depth range.
