Quartz ICP® Links
Link-style sensors measure dynamic compression and tension. They are constructed using a force ring that is under compressive pre-load between threaded mounting hardware. The threaded mounting on both ends of the sensor supports integrated link-style installations. Versions offering full-scale measurements of 10 lb to 50k lb (45 N to 220k N) compression and 30k lb (130k N) tension are available.
Applications:
- Tensile Testing
- Press Monitoring
- Material Testing
- Machine Process Monitoring
- Tension & Compression
- Push Rod Testing
- Repetitive Operations
- Press Force Monitoring
Tips from Techs:
The output characteristic of piezoelectric sensors is that of an AC coupled system, where repetitive signals will decay until there is an equal area above and below the original base line. As magnitude levels of the monitored event fluctuate, the output will remain stabilized around the base line with the positive and negative areas of the curve remaining equal.
Polarity of Quartz Force Sensors
The output voltage polarity of ICP® force sensors is positive for compression and negative for tension force measurements. The polarity of PCB® charge output force sensors is the opposite: negative for compression and positive for tension. This is because charge output sensors are used with external charge amplifiers that exhibit an inverting characteristic. Therefore, the resulting system output polarity of the charge amplifier system is positive for compression and negative for tension; same as for an ICP® sensor system (reverse polarity sensors are also available).
