The Ephy Mess 903120417000004 (Catalogue title: 903120417000004) is a specialized temperature sensor featuring a single cold conductor (EPTC-SGH) with 1x barium titanate. It operates with a nominal activation temperature (NAT) of 090°C, resistance under 100Ω, and a tolerance of ±5K in accordance with DIN VDE V 0898-1-401. Designed for hazardous environments, it holds ATEX (iBExu 14 ATEX 1281U, II 2G Ex eb IIC Gb, II 2D Extb IIIC Db) and IECEx (IBE 14.0058U, Ex eb IIC Gb, Ex tb IIIC Db) certifications. This unit includes a screw housing, press surround, and a step sleeve or socket measuring ø7x22mm, with a total length of 37mm. The fixed VSB screw housing is constructed from 1.4404 / AISI 316L stainless steel and features an M5x7.5mm / SW 10 specification. It is equipped with a 3000mm supply line (hose line with 2x0.22mm² silver-plated copper, FEP, and silicone, 4.00mm diameter). The measurement range and ambient temperature range both span from -45°C to +180°C, supported by a dielectric strength of 2.5 kV AC at 50 Hz for 1 minute.
