L-shaped bayonet thermocouples use a 90° design for easy installation and accurate sensing where a bend is needed to reach the measurement point. Spring rotate variants mount the probe on a rotating, spring-supported assembly that keeps consistent contact pressure against the surface. Mineral-insulated bayonet and LRB bayonet types use the same spring-loaded bayonet cap for quick installation and removal, while compression-spring and spring-holder variants are common in plastic machinery for reliable contact under vibration.
