From the manufacturer's datasheet for SFK02+ passive.
Overview
The SFK02+ measures temperature in gases and liquids in HVAC systems. It screws directly into a bonded pocket, and the measuring insert can be exchanged without taking the whole sensor apart. SFKH02+ types with a 70 mm neck pipe are for insulated pipework. This page covers the passive versions, which have a resistance element and no transmitter. The listed parts are Pt100, Pt1000, Pt1000 1/3 DIN, NTC10k, Ni1000 and Ni1000TK5000, each with a probe of 50, 100, 150, 200, 250 or 450 mm. The enclosure is a USE-S with a quick-release cover.
