The environments in which
capacitive sensors are
in stall ed can often be un sta-
ble as regards to tempera-
ture, humi dity , object dis-
tance and industrial (noise)
inter ference. Because of
this, Carlo Ga vazzi offers
as standard features in all
TRIPLESHIELD
TM
capacitive
sensors a user-friendly sen-
sitivity adjustment instead
of a fixed sensing range.
Likewise, these sensors
provide an extend ed sen-
sing range to accommodate
mechanically de mand ing are-
as and tem perature stability
to en sure high immunity to
elec tro magnetic interference
(EMI) and a minimum need
for adjusting sensitivity if the
temperature varies.
Note:
Sensors are factory set
(default) to nominal sensing
range S
