Klay Instruments Pt100 sensors deliver precise temperature monitoring across industrial processes with measuring ranges from -50 °C to +400 °C. Choose from 3- or 4-wire configurations with accuracy to 1/10 DIN class, multiple insertion diameters (3–20 mm), and lengths up to 4 m to suit any application. Rugged stainless steel construction (AISI 316 wetted parts) with IP65/IP68 protection ensures reliable performance in harsh environments. Optional head-mounted transmitters provide 4-20 mA output with ATEX, HART, Profibus PA, or IO-Link integration for seamless system connectivity.
