From the manufacturer's datasheet for PR25 passive.
Overview
The PR25 is a surface sensor with a connection cable and an aluminium prism for measuring the temperature of cold or hot water pipes and other suitable surfaces. The passive version has no electronics and gives a resistance from the element fitted: Pt100, Pt1000, Pt1000 1/3 DIN, Ni1000, Ni1000 TK5000, several NTC types, KTY81 types or an LM235Z. All parts listed here are rated to 100 °C and have a 1 m cable. The cable ends in a USE-S enclosure with a quick release cover, a removable M20 cable entry and plug-in terminals.
