Open Disc Terminal Blocks

The open disc terminal blocks are available for both single and dual element thermocouples or single-element RTD assemblies. They are available in two different materials. Ceramic discs are rated for 1000ºF (530ºC) and silicone/glass fiber discs are rated for 350ºF (117ºC). Silicone glass/fiber has a higher resistance to vibration and thermal shock than do the ceramic discs.
Each disc is assembled to a 1" O.D. x 1/8" thick Brass (standard) or optional stainless steel back-up plate by two screws, and the plate is directly brazed to the sensor sheath.
