Notes
1. Measured with AMP connectors in still air with solid copper wires
of 1 mm diameter.
2. 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
3. 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
AMP connectors for easy connection
Excellent accuracy over a wide temperature range
Old part number was 2322 640 90042
Component in accordance to RoHS 2002/95/EC and
WEEE 2002/96/EC
APPLICATIONS
Sensors for water temperature control in, for example:
– washing machines
– dish washers
– heat pumps
– electric boilers.
These thermistors have a negative temperature coefficient.
The device consists of a ceramic material which is mounted
in a capsule of stainless steel and provided with two 6.3 mm
tinned bronze spade connectors.
The device is non-flammable and the housing is stainless
steel in accordance with “DIN 1.4301” (× 5 CrNi 18 9).
MOUNTING
Connect to two FASTONS 6.3 x 0.8 or equivalent.
PACKAGING
The thermistors are packed in cardboard boxes; the smallest
packaging quantity is 50 units.
