Quartz Charge Force Rings
Ring-style sensors measure dynamic compression. Tension measurements are also possible if the unit has been installed with proper preload. The through-hole mounting supports platform, integrated link, and support style installations using either a through-bolt or the supplied stud.
- Measurement ranges from:
5,000 lbs to 100,000 lbs (22.3 kN to 450 kN)
- Wide Operating Temperature Range
-100 to +400 °F (-73 to 204 °C)
- Quartz & Stainless Steel Construction
- Scaling & DTC determined by Charge Amplifier
- Models with UNF &/or Metric Studs
- Crimping, Stamping, & Press Monitoring
- Machinery Mount Forces
- Mechanical Impedance Testing
- Material Testing
- Tablet & Punch Presses
- Roll Nip Profile
- Machinery Process Monitoring
- Stamping & Forming
- Force Limited Vibration Testing
Versions offering full-scale measurements of 5,000 lbs to 100,000 lbs (22.3 kN to 450 kN) compression are available. Tension range is dependent upon the amount of applied preload 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.
