Operating temperature range:
at zero dissipation
Bead thermistor with negative temperature coefficient, in a
glass envelope with two tinned durnet (CuNiFe) leads. The
device is non-flammable.

Note
1. Response time in silicone oil MS200/50. This is the time needed
for the sensor to reach 63.2% of the total temperature difference
when subjected to a temperature change from 25 °C in air to
85 °C in oil.
