SENSAPHONE 10K ImmErSION TEmPErATurE
SENSOr FGD-0105
GENErAl INFOrmATION
The active element is precision thermistor
material accurate to within .36°F. Refer
to controller literature for overall system
accuracy.
WIrE
The sensor does not require shielded cable
or even twisted pairs. However, most
micro–based controllers operate more reli-
ably when shielded cable is used. Sensor
leads are rated for 105°C.
WArNING
Connection to the sensor to any voltage
source other than the controller specically
designed for it can cause irreversible dam-
age. The sensor resistance can be checked
with a VOM without harm.
CONNECTIONS
Solder connections are by far the most reli-
able and trouble free over extended periods,
and thus are preferred. Crimp type butt
splices are the second choice and usually
prove satisfactory. Simple wire nut connec-
tions are an invitation to long term trouble.
This is an electronic hook up, not a power
hook up. Equally important is that the eld
connection be made as far as possible from
the sensed media. Use the full lead length
provided to avoid condensation at the eld
connection.
APPlICATION
rESTrICTIONS
Care should be taken in sensing tempera-
tures in areas subject to rapid change in
ambient wet bulb temperatures. Sensing
media where it is possible for the sensed
temperature to fall below the ambient dew
point can cause condensation on the sensor
itself and on the eld connection.
