Quartz Charge Force Rings

Ring-style sensor configurations measure dynamic compression. Tension measurements are also possible if the unit has been installed with proper pre-load. The through-hole mounting supports platform, integrated link, and support style installations using either a through-bolt or the supplied stud.


  • Capacities from 5,000 lbs to 100,000 lbs
    (22.3 kN to 444.8 kN)
  • Quartz & Stainless Steel Materials
  • Welded Hermetic Construction
  • Wide Operating Temperature Range
    -100 to +400 °F (-73 to 204 °C)
  • Scaling & DTC determined by Charge Amplifier


  • Semiconductor Manufacturing
  • Crimping, Stamping, & Press Monitoring
  • Machinery Mount Forces
  • Mechanical Impedance Testing
  • Material Testing
  • Tablet & Punch Presses
  • Roll Nip Profile
  • Balancing
  • Machinery Process Monitoring
  • Stamping & Forming
  • Force Limited Vibration Testing

Versions offering full-scale measurements of 5000 lbs to 100,000 lbs (22.3 kN to 444.8 kN) compression are available. Tension range is dependent upon the amount of applied pre-load and strength of mounting stud used. Applications include tablet presses, stamping, punching and forming operations, balancing, machinery studies, and force-controlled vibration testing.

Tips from Techs: Preloaded & Force Rings

PCB® ring-style 1-component and 3-component force sensors are generally installed between two parts of a test structure with the supplied elastic beryllium-copper stud or customer-supplied bolt. The stud or bolt holds the structure together, and applies preload to the force ring. Typically a component of the force between the two structures is shunted through the mounting stud. The amount of force shunted may be up to 7% of the total force for the beryllium-copper stud supplied with the sensor, and up to 50% for steel studs. Contact a PCB® application specialist for proper pre-load and calibration for your particular application.
