From the manufacturer's datasheet for SFK01 passive.
Overview
The SFK01 measures the temperature of liquids in water lines and tanks. The thermowell is built in, so the sensor screws straight into a G1/2 inch thread and can be changed without draining the system. The passive sensor element is chosen by code: Pt100, Pt1000, Pt1000 1/3 DIN, NTC10k, Ni1000 or Ni1000TK5000. The probe is available in lengths of 50, 100, 150, 200, 250 and 450 mm, in an IP65 aluminium housing.
