Product Manual | Lynx™ Embedded Sensors LES‑B‑127‑50/125/500/2000

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.

LES‑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 LES‑B‑127‑50/125/500/2000 sensors;

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.

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.

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.
