Product Description

The Shimpo DT-315A-230V battery or line-powered digital stroboscope has a xenon flash tube, internal and external trigger modes, and time and phase shift to provide stop-motion or slow-motion viewing of moving machinery. It is used for motion analysis, preventive maintenance, printing inspection, and speed measurement of repetitive motion. The xenon flash tube has a 10 to 40 microsecond flash duration for crisp images in brightly lit areas and a flash timer conserves flash tube life. Xenon flash tubes have brighter light output and a shorter flash duration than LED lights. Bright light output is required for quality images in brightly lit areas, and shorter flash durations provide sharper images, especially at high rates of speed. A high-polish focused reflector eliminates blind viewing areas. Internal and external trigger modes have a 0 to 35,000 flashes per minute (FPM) range and an accuracy of + or - 0.01%, or + or - 1 digit. Built-in multiply-by-2 and divide-by-2 functionality allows the operator to distinguish true RPM from harmonics. Internal mode phase shift has a 360 degree range in six seconds. External mode has a phase shift range of 0 to 360 degrees in one-degree increments and a time delay of 0 to 2,000 milliseconds (msec) at speeds between 40 and 10,000 FPM. Time delay and phase shift enable the operator to adjust the focal point of the object to any point in the rotation without moving the trigger point. Synchronous output enables the stroboscope to drive other strobes for wider coverage. The stroboscope can be powered by the internal rechargeable battery or 230V AC line power. An integrated mounting thread and continuous duty cycle allow for permanent installation and long-term use without the need for cool-down periods. The aluminum housing provides durability. The stroboscope includes a flash tube removal tool, a handle, and instructions. Stroboscopes are used in a variety of settings including manufacturing, printing, education, and photography.

Stroboscopes evaluate the functionality of fast-moving rotational objects, such as belts, fan blades, and other machine parts. They are used in industries such as manufacturing, entertainment, high-speed printing, wood and metal turning, and in education and research settings. Stroboscopes have a flashing light (strobe) that, when directed at a moving object, makes the object appear to be stopped or moving in slow motion. This enables the operator to evaluate machine performance without stopping the machine. Stroboscopes use either xenon flash tubes or LED light sources. The strobe is triggered either internally, which allows the operator to manually adjust the flash rate, or externally and automatically by a peripheral sensor. Multiply-by-2 (2/4 or 2X) and divide-by-2 (1/2) functionality enables the operator to verify the actual revolutions per minute (RPM) and to distinguish true RPM from harmonics. Phase shift adjusts the flash delay in degrees of a full rotation, and time delay adjusts the flash delay in seconds or fractions of a second. Input and output features enable the operator to use peripheral sensors to trigger flash rates, to perform tachometer operations, or to daisy-chain stroboscopes.

Shimpo Instruments manufactures force, torque, and speed evaluation instruments. The company, founded in 1974 and headquartered in Itasca, IL, meets International Organization for Standardization (ISO) standard 9001.
