Notes
(1) The response time is the time necessary to change 63.2 % of the
total difference between the initial and the final body
temperature, when subjected to a step function change in
ambient temperature.
Step change:
a. Initial temperature: Air at 25 °C
b. Final temperature: Water at 100 °C
(2) The temperature gradient is the difference per degree Celsius
between the true temperature of the liquid (water) and the
temperature measured by the sensor.

FEATURES
• High mechanical strength
• FASTON connectors for easy connection
• Accuracy of ± 1 °C between 25 °C and 85 °C
• Compliant to RoHS Directive 2002/95/EC and in
accordance to WEEE 2002/96/EC
APPLICATIONS
• Sensors for water temperature control in, for example:
- Washing machines
- Dish washers
- Heat pumps
- Electric boilers
DESCRIPTION
These thermistors have a negative temperature coefficient.
The device consists of a soldered ceramic chip which is
mounted in a capsule of stainless steel and provided with
two 6.3 mm tinned spade connectors.
The device is non-flammable and the housing is stainless
steel.
MOUNTING
Connect to two FASTONS 6.3 x 0.8 (0.25" x 0.032")
receptacle or equivalent and mounted with a watertight
sealing.
