Danfoss MBT 3252 temperature sensor, Pt 100 Class A, 50 mm insertion, NPTF 1/4-18 process connection (code 084Z2485)

Danfoss MBT 3252 insertion temperature sensor with exchangeable measuring insert, code 084Z2485 (type designation MBT 3252-0001-0050-0931-0000). Pt 100 platinum measuring element (100 ohm at 0 C), Class A tolerance per EN 60751; 4-wire connection. Insertion length 50 mm; NPTF 1/4-18 tapered male (ANSI/ASME B1.20.3 dryseal) process connection; AISI 316 Ti stainless-steel protection tube, 8 mm diameter. Measuring range -50 to +200 C (-58 to +392 F); resistance (ohm) output. Type B connection head, Pg 16; IP65 enclosure per IEC 60529. CE marked. This is the resistance-sensor variant of the MBT 3252 (distinct from the 4-20 mA transmitter 084Z2384).
