A CompoBus/S network allows the user to centralize the CPU and distribute the I/O remotely via a high speed communications network. This provides an optimum solution for applications where I/O must be spread out over distances and provides incredible flexibility and efficiency. Multiple types of remote devices can be added to a CompoBus/S network including Discreet or analog I/O, sensor terminals, sensor amplifiers, or even Omron micro PLCs creating a wide area control system that cannot be achieved with standard

1. SENSOR CONSTRUCTION: Relative humidity sensors use an
industrially proven thermoset polymer, three layer capacitance
construction, platinum electrodes and except for high temperature
versions (shown bottom), on-chip silicon integrated voltage
output signal conditioning. (RHIC Sensor).
In operation, water vapor in the active capacitor’s dielectric layer
equilibrates with the surrounding gas. The porous platinum
layer shields the dielectric response from external influences
while the protective polymer over layer provides mechanical
protection for the platinum layer from contaminants such as dirt,
dust and oils. A heavy contaminant layer of dirt will slow down
the sensor’s response time because it will take longer for water
vapor to equilibrate in the sensor.
TEMPERATURE & HUMIDITY EFFECTS: The output of all
absorption based humidity sensors (capacitive, bulk resistive,
conductive film, etc.) are affected by both temperature and
%RH. Because of this, temperature compensation is used in
applications which call for either higher accuracy or wider operating
temperature ranges.
When temperature compensating a humidity sensor, it is best to
make the temperature measurement as close as possible to the
humidity sensor’s active area, i.e. within the same moisture
micro-environment. This is especially true when combining RH
and temperature as a method for measuring dew point.
