MAINTENANCE
Strain gage sensors require little maintenance.
CLEANING
Pull sensors from the mold and clean out
the pockets and channels when a mold
is pulled for preventative maintenance.
LS‑B‑127‑50/125/500/2000 sensors must be
installed in pockets free from oil, dirt, grime,
and grease.
TESTING & CALIBRATION
TESTING SENSORS
Basic force tests are easily performed on the
LS‑B‑127‑50/125/500/2000 sensor; a small,
even amount of force applied to the sensor
head loading nub is sufficient to determine if the
sensor is correctly reading pressure.
CAUTION
NEVER strike the sensor head
with excessive force; failure to comply will result in
damage or destruction of sensor.
RJG, Inc. offers the following tools to test
sensors.
1.
Sensor eValuator
The Sensor eValuator provides diagnostics
on typical sensor problems such as sensor
drift, preload, and zero shift, and can also
detect sensor installation errors caused by
improper pocket dimensions, damaged wires,
and damaged sensor heads. A test report with
sensor configuration can be emailed or printed
from the device. This device allows testing of up
to thirty‑two sensors at one time and can verify
that a force was applied to the sensor.
2.
eDART Software—Raw Data Viewer
The eDART Raw Data Viewer displays the status
of the sensor, either Valid , No Reply , Stale , or
Invalid .
•
A Valid sensor has raw counts that change
when force is applied to the sensor; this
indicates a properly working sensor.
•
A No Reply sensor is not communicating with
the
eDART ; the sensor may be unplugged.
•
A Stale sensor indicates a sensor that is
unused.
•
An Invalid sensor will indicate a Failure of
either
Over‑range (Ovrng) or Under‑range
(Undrng). The Ovrng indicates the sensor’s
calibration has changed too far in a positive
direction, outside of the upper specification.
The Undrng indicates that the sensor’s
calibration has changed too far in a negative
direction, and the sensor may report a
number below zero when load is applied.
