This non-armored transducer is optimized for tight mechanical clearances where a standard 8 mm probe is too large to interface with the machine casing. It is extensively utilized in critical rotating machinery—such as high-speed compressors, small steam turbines, and pumps—to monitor radial vibration and axial position.
