0.25 seconds (grounded)
for the sensor to reach 63.2%
of a change in mounting
surface temperature.


Insulation Resistance
The insulation resistance
between the outer metal faces
and the common leadwires is:
50 megohms minimum with
50 Volts DC applied to a dry
sensor at room temperature.

Lead Wire
#20 AWG stranded
Thermocouple conductors;
fiberglass insulated
with fiberglass overbraid.

Sensors can be bolted, clamped
or welded into place.
