STRAIN GAUGE SENSOR

STRAIN GAUGE SENSOR
Description The sensors are produced in a full resistive Wheatstone bridge configuration
that is temperature and creep compensated. It uses a thin foil as one of the
resistive elements of the bridge. If a force is applied (weight) such that the
measuring foil is stretched, the lengthening of the foil causes its resistance to
vary. This change in resistance is detected and passed to a high gain DC
amplifier.
Testing/
Adjustment
The sensors do not require adjustment. In use the assemblies are calibrated -
see the Squeegee chapter or the relevant underscreen cleaner chapter for
details.

TEMPERATURE AND HUMIDITY SENSOR
The temperature and humidity sensor is an integral part of the print carriage
I/O Node 3 PCB and as such there is no adjustment and setting available for
this sensor.
