LED Stroboscope for iron and steel industry

LS-V series LED Strobe/CB-LSV Controller

LS-V series LED Strobe/CB-LSV Controller

The LS-V series is a complete set of multifunction LED stroboscopes. It supports diverse stroboscope applications such as surface inspection of steel sheets, paper, and film, checking of printed materials, observation of high-speed rotation and high-speed movement, and measurement of rotation speed. It is equipped with diverse flash functions such as internal trigger flashing, external trigger flashing, delay, frequency division, and slow motion.

Features

  • Ultra-wide frequency range of 30–360,000 FPM in internal trigger flashing.
  • Extensive lineup in short-to-long sizes (flashing surface width: 250, 500, 1,000, 1,250, 1,500, and 2,000 mm).
  • Reduces the labor and cost of replacing lamps and filters.
  • Controller can be attached to or detached from an LS-V unit.
  • Simple settings by knob-based operations.
  • Equipped with diverse flash functions such as internal trigger flashing, external trigger flashing, delay, frequency division, and slow motion.
  • Up to twelve LS-V units can be simultaneously controlled with one Controller.
  • Enables settings to be saved for a maximum of 10 cases matching a variety of flash conditions.
  • Enables flash timing to be set using a printing-machinery encoder signal and number of printed sheets.

Typical Applications

  • Inspection of sheet metal surfaces in iron and steel rolling/processing presses
  • Check for color, misalignments, faintness, omissions, and blemishes in printed matter
  • Measuring the spindle rotation speed, yarn balloon inspection, loom timing adjustment, etc. in textile production
  • Visual inspection of high-speed rotation and high-speed movement
  • Measuring rotational speed and checking operation of various rotating devices such as motors
  • Observing the vibration of automobile and motorcycle components

Uniform and bright illumination

Flashing surface comes in six sizes: all 90 mm high with widths of 250 mm, 500 mm, 1,000 mm, 1,250 mm, 1,500 mm, and 2,000 mm. Emits bright and even light using high-brightness white LEDs.

Reduces the labor and running costs of replacing lamps

The use of LEDs reduces the labor and running costs of replacing lamps (*). Natural (fan-less) cooling makes maintenance such as replacing filters unnecessary.

(*) Reduces cost by about 300,000 yen per LS-V unit per year (compared with Sugawara SS-800DL).

Diverse and easy-to-use functions

Controller is easy to operate using a knob and a single screen. Up to 10 settings can be saved using a memory function. It is equipped with diverse flash functions such as internal trigger flashing, external trigger flashing, delay, frequency division, and slow motion.

Controller CB-LSV
Controller display

Up to twelve LS-V units can be simultaneously controlled with an attachable/detachable controller.

It can be used as an integrated stroboscope or separately from the controller to support a variety of usage environments. Multiple LS-V units can be connected enabling simultaneous illumination of separated locations or extension of the range of illumination.

Example of wiring when connecting

Encoder-signal frequency division function enables the number of flashes per one encoder rotation to be set.

In the inspection of printed matter, the number of flashes can be easily set using the conveyor encoder signal and the number of printed sheets. For example, for an encoder with 60 P/R and 7 printed sheets per rotation, there is no need to calculate the division ratio (60÷7=8.5714…)—you only have to set the number of pulses “60” and number of printed sheets “7”.

Mounting brackets simplify installation of stroboscope and adjustment of mounting angle.

Two types of Mounting brackets to choose from: L-type and I-type. Using the L-type enables the LS-V to be used as a tabletop stroboscope.
