Combination Conductivity/Temperature/Depth/pH
Sensor
Make
more accurate electrical conductivity, temperature, depth (pressure) and
pH measurements with state of the art CTDP300 sensor.
The Conductivity/Temperature/Depth/pH Sensor provides the accuracy
and reliability required for a wide range of demanding measuring applications.
With state of the art ceramic pressure and toroidal conductivity
measurement technologies the CTDP300 Sensor guarantees long term performance
and highly accurate temperature compensated measurements in the harshest
of environments.
The Greenspan Conductivity/Temperature/Depth/pH Sensor provides numerous
state of the art technical features:
-
Toroidal conductivity sensing technology eliminates electrode corrosion
effects, guaranteeing long life and reduced Þeld 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).
-
Innovative, optically isolated signal conditioning electronics ensure
true and accurate pH readings at all times.
-
Field proven gel-filled double junction pH electrode provides long term
accuracy.
-
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 Greenspan calibration
software runs on a portable PC.
Reliability
The CTDP300 Sensor combines robust, sealed construction with a combination
of high performance sensor technology to offer unparalleled reliability.
The high reliability of sensors means critical measurements are not lost
through sensor down time. Time wasting unscheduled site visits are therefore
minimised.
Accuracy
Toroidal conductivity sensing technology substantially eliminates inaccuracy
in conductivity measurements due to temperature and electrode effects.
Accuracy in pressure measurement is ensured 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. The gel-filled double junction
pH electrode with optically isolated signal conditioning electronics provides
long term accuracy in pH measurements. On-board microprocessor compensation
substantially reduces system non-linearity and temperature drift errors.
Intelligent Features and Data Acquisition
The intelligent Conductivity/Temperature/Depth/pH Sensor model CTDP300
is a complete, self-contained conductivity, depth (pressure), temperature
and pH measurement and data logging system. The CTDP300 provides sophisticated
and versatile data acquisition, control and communications capabilities.
Standard features 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 CTDP300 make remote site
logging of key water parameters easier than ever. In combination with an
external data modem and mobile phone, the CTDP300 enables remote uploading
of logged data and re-programming of logging schedules. In addition the
CTDP300 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 CTDP300 can be powered using external batteries (via the sensor
cable) or with optional lithium battery pack, which can be Þtted
as an extension to the sensor body, making a fully self-contained measurement
and logging system.
The CTDP300 also provides a supplementary rain-gauge input. With
the addition of a tipping bucket raingauge, the CTDP300 becomes a completely
self-contained hydrographic measuring station, enabling correlation of
rainfall and river height data from one compact monitoring package.
