The ST-3711 measures displacement with the conversion of light volume by irradiating the light from the flashing fiber in the thin probe and detecting the reflected light by receiving fiber in the probe. The fiber can resist the high temperature, magnetic field and oil proof environment. The probe can process finely, and respond rapidly. Each filter is prepared, and is suitable to measure high-speed vibrators and rotator. Also, it is used to adjust the light volume matching the reflected surface, irrespective of the material of the measuring object. Use this meter after calibration.

Features

	Rapid response (100kHz) is available.
	Measurements are performed in a high temperature, magnetic field and oil proof environment.

Note) The combinations of probes and equipment are specified. The R random arrangement, other H half, and C coaxial etc. can be made (option). The figures above show the average value during calibration. There is the possibility of an approximate 20% difference due to the specifications of each probe. Custom-made probes are sold separately.
