Temperature sensor with steel head (SEN118A2B) datasheet


Do you know what’s the datasheet for the Temperature sensor with steel head (SEN118A2B) ?
I can’t find any reference on the web.

… or at least two points since it should be reasonably linear at first :

how many ohms at 20degC ?
how many ohms at 100degC ?

I fear to calibrate a temperature sensor since a teacher told me years ago : “A thermometer can only give the temp of … itself !”

Maybe someone already have a resistance/temperature curve for this sensor ?

I also need the temp. range for this sensor
