SCALES

SCHMIDT scales are manufactured according to the most stringent quality requirements. Printed scales are not used. Instead, each scale is individually marked for the instrument involved. This ensures highest quality. Our special procedure makes it possible to provide tension meter MK

  • calibrated to custom supplied material
  • fine tuned to a specific tension range
  • other units of measure such as g

GUIDE ROLLER

ATTACHMENT

Code D – MIN/MAX Limits

When the tension exceeds or falls below the adjusted tension range, a signal according to the circuit diagram may be shown. The range will be adjusted with the screws. It is a mechanical contact. Example for a circuit
