The PT100-14 bolt-on ring terminal sensor is suitable for any application requiring direct surface temperature measurement via a bolted or screwed connection.

It is widely used for motor and generator surface temperature monitoring, where the ring lug is bolted onto the motor frame or end-bell to detect overheating before thermal protection trips. In power electronics and heat sink monitoring, the sensor is screwed directly onto heatsinks, bus bars, or IGBT modules to provide closed-loop thermal management feedback. For pipe outer-wall temperature measurement, the ring terminal is clamped or bolted to the pipe surface to monitor fluid temperature without penetrating the pipe wall, making it ideal for retrofitting existing pipework. The sensor is also commonly used in bearing housing temperature monitoring on rotating machinery,transformer and switchgear thermal monitoring, battery pack and energy storage temperature management, and OEM machine-building applications where a compact, bolt-on temperature sensing solution is required.
