Models Offered
SC-PM4, for use with sensors providing a 0-1V DC output
SC-PMD4, for use with sensors providing a mV/V output

Panel mount digital display for up to for 4 tension sensors. Outputs: USB, RS 422 and 0-10V DC analog.
4 different calibrations for customer supplied material can be saved for each channel.
Using the USB or RS 422 output all tension readings can be sent to PC for data analyzing and storage.


  • SC-PM4 is suitable to connect max. 4 sensors (different ranges are possible) providing 0 – 1 V DC output
  • SC-PMD4 is suitable to connect max. 4 sensors (different ranges are possible) providing a mV/V strain-gauge output
  • Backlight, graphic LCD display with 2 different display modes:
    – Readings with alarm control
    – Bar chart, reading and alarm control
  • Various output signals are available:
    – digital (standard): USB (front side), RS 422 (rear side)
    – analog (optional): 0 – 10 V DC (rear side)
  • Adjustable damping for easier reading, if tension fluctuates
  • User set limits (Min and Max alarms) and open collector output for external control units
  • Each channel of display unit SC-PM4 can be scaled to engineering units as grams, cN, daN, N, g, kg, lb and oz depending to the used sensor
  • Easy calibration to customized material by the operator – zero and gain calibration is required for the connected sensor
  • Possibility to store 4 different materials curves for each channel
  • Easy operation using keys: menu for configurating the device (alarm limits, damping, units, tension range, language, material curve)
  • The set-up menu can be password protected
  • Panel mount display unit (1/4 DIN IEC 61554 cutout – 91.5 x 91.5 mm)
  • Required power supply +15…24 V DC (regulated)
