✳️ Load monitor Riken Optech PLA-4α

PLA-4α has the function of detecting the press load with four(4) pieces of strain gauge sensors. It displays the accurate load during press processing, and output stop signals and stops a press machine immediately when abnormality is detected. Monitoring cannot be ignored when there are eccentric loads for each stroke. Furthermore, load monitoring extends the life of dies, prevents friction and wear of presses, also promotes quality control and rationalization.

✳️ Features

  • Suited for crank type and servo type press machines.
  • Responds to static load.
  • A method of obtaining the total load (Maximum total value or total values considering eccentricity) according to work piece.
  • Provided with an output function for press machine protection (overload otherwise known as capacity alarm).
  • Provided with a function of inputting the number of usable strain sensors (1ch~4ch).
  • Provided with an automatic zero point compensation function.
  • Adopts a digital sensitivity setting method
  • Adopts a 5-digit display.
  • Provided with an LED level meter display function.
  • Higher visibility by use of blue LEDs.
  • Better operability by adoption of dial type setting.
  • Provided with a function of malfunction protection by password setting.
  • The reverse load can be displayed.
