The
Monitor Series of data loggers has been designed to provide the greatest flexibility of
use for all size installations. The Monitor Series is fitted with key-pad,
display, power supplies, signal conditioning, and communications
facilities.
Connections to sensors are
then made to multiplexers, each of which has been optimised for a
particular sensor combination.
-
Electro-level Multiplexer. This provides an AC energising supply and has been
optimised for use with up to 32 electro-level, potentiometric, or
temperature sensors.
-
Vibrating wire multiplexer (16 or 32
channel).Designed to interface to 16
vibrating wire strain gauges each with a temperature sensor, or 32
vibrating wire gauges without temperature sensors.
-
General Purpose Multiplexer(32 channel).
The General Purpose (G.P.) multiplexer allows mixtures of different
sensors to be used with the greatest flexibility. Facilities are provided for DC energised transducers of
half and full bridge types and AC energised transducers (e.g. LVDTs) of
full bridge. In addition it may also be used with vibrating wire sensors,
with or without
thermistor sensors in built. Channels of different types may be freely
mixed.
Up to 128 Monitor Series loggers may be connected using the RS485 ports
giving a total capacity for > 30,000 channels.
