From the manufacturer's datasheet for KFK03 passive.
Overview
The KFK03 is a passive temperature sensor for supply and exhaust air ducts and other gaseous media, built to connect to a higher level controller. It fits in a duct with a mounting flange, or it can go in a thermowell as an immersion sensor. The probe is 8 mm stainless steel and comes in four lengths. The sensing element on the parts here is a Pt100, Pt1000, Pt1000 1/3 DIN, NTC10k, Ni1000 or Ni1000 TK5000. The sensor sits in an aluminium connection head with an M20 cable entry and a terminal block. For duct use, fit it with the stainless steel MF8 mounting flange. For immersion use, fit it in a THVA thermowell.
