Note: Support for specific interfaces or functions vary and are dependent upon the
model supplied.
Sensors provide information for various physical parameters, and this information is
transferred to the logger via an appropriate electrical interface.
Each interface has associated logger settings for initiating the measurement and also to
correctly interpret the numeric data obtained. IDT is used to manage the settings.
Wired connections are made to the logger via a connector mounted through the logger
case. Various sizes are available and can contain either pins or sockets. Some examples
are shown in Figure 8 and Figure 7. A dust-cap is available as an option to keep unused
connectors free of water and debris (see Figure 6).
Some connectors are single-purpose in nature (e.g., For connection of a single sensor).
However, other connectors may be multi-purpose (e.g., Having both a connection for a
programming cable and also for the supply of power from an additional battery).
Where a connector is multi-purpose, a Y-adaptor cable may be required to split out the
various functions.
For water pressure measurement, the electrical connection to the sensor may be made
via a standard electrical connector. This interface
is known as an “External Pressure”
type. It allows a cabled pressure transducer (sensor) to be connected to the logger.
HWM can provide a variety of cabled pressure sensors with the appropriate connector
for the logger.
An alternative for water pressure measurement is for the transducer
(sensor) to be built into the unit, as shown in Figure 9. This logger
interface is known as an “Internal Pressure” type. It allows pressurised
water to be connected to the logger directly, via the use of hoses fitted
with a quick-release connector.
For antenna, a different type of connector is used. Refer to section
5.18.
