A hose with male and female connectors is available to connect the logger to the pressure
monitoring point.
Care must be taken to avoid pressure shock when connecting to the transducer, as this can
damage or destroy the sensing diaphragm.
1.3.3.3 Analogue Inputs
Analogue inputs are of two types - general purpose and dedicated integral pressure
transducer.
General analogue inputs may be voltage or current.
Voltage input range is nominally 0 - 21V DC. Voltages outside this range require a special
cable; standard voltage ranges available are 0 - 5V and 0 - 10V.
Current input requires a special cable. This is suitable for 0 - 10mA, 0 - 20mA and 4 - 20mA
ranges.
If the logger starts before the sensor is connected, no malfunction will occur but the data up to
the time when the sensor was connected will be zero values.
1.3.3.4 Communication Link
The communication link is a cable which interfaces directly to a PC serial port or to a Psion
Workabout. Communication is at standard RS-232C levels. Loggers must be configured by
PC or Workabout before use.
The communications socket on submersible loggers is used also for connection of the
Auxiliary Battery Unit.
1.3.3.5 Modem Connection
The modem connection is a direct lead between the logger and the external PSTN linebox.
