APPLICATIONS
Temperature measurement and control up to 300 °C.
Bead thermistor with negative temperature coefficient, in a
glass envelope with two tinned durnet (CuNiFe) leads. The
device is non-flammable.
MOUNTING
By soldering in any position.
PACKAGING
The thermistors are packed in cardboard boxes; the smallest
packaging quantity is 100 units.
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.
