COMET explosion-proof Pt1000 immersion probe, -30 to +180 °C, RCA connector

COMET SN263C – Explosion-Proof Pt1000 Immersion Probe for Zone 2/22, –30 to +180 °C, CINCH Connector

The COMET SN263C (Pt1000TG8Ex/C) is an explosion-proof Pt1000 immersion probe designed for safe use in potentially explosive atmospheres – Zone 2 (Gas) and Zone 22 (Dust) according to ATEX Directive II3G Ex ec IIc T3 Gc and II3D Ex tc IIIC T60 °C...230 °C Dc. With its certified design (FTZU07 ATEX 142X) and wide measuring range from –30 to +180 °C, it is ideal for chemical plants, gas installations, tank farms, mills, silos, paint booths, woodworking, or any environment where explosive gases or combustible dusts may occur.

The Class A Pt1000 sensor ensures maximum accuracy and long-term stability. The corrosion-resistant stainless-steel housing (DIN 1.4571) provides high durability and chemical resistance. The shielded silicone cable (1 meter standard) remains flexible and heat-resistant. The CINCH connector allows quick and safe connection to COMET transmitters or any Pt1000 input unit – all explosion-proof.

The probe is fully IP67-rated – perfectly sealed against dust, moisture, and condensation. The extremely fast response time (t_0.5 < 5 s in flowing water) ensures precise control and quick reaction to temperature changes. The EU Declaration of Conformity and ATEX certificate make it the safe choice for Ex environments.
