From the manufacturer's datasheet for TF25 passive.
Overview
The TF25 passive is a cable sensor for temperature measurement in HVAC and refrigeration applications. With a thermowell it can also measure liquids. The stainless steel probe is 6 mm in diameter and is fitted to a connecting cable that runs to a USE-S terminal housing. Choose the sensor element (Pt100, Pt1000, Pt1000 1/3 DIN, Ni1000, Ni1000TK5000 or NTC10k), the temperature rating of the cable from 100 °C to 400 °C, and the probe length of 50, 100 or 150 mm. The cable is PVC, silicone, high temperature silicone or fibreglass, depending on the version. Most versions have a 1 m cable and the 400 °C versions have 2 m.
