Force, Load, and Strain
Force, Load, and Strain – sensors for testing, monitoring, and process control
PCB
® offers a vast selection of quartz piezoelectric and strain gage sensors for dynamic force, dynamic strain, and static load measurementrequirements. The variety of available configurations supports a multitude of installation options. Whether it’s a mechanical componentdurability test, assembly force control requirement, or an end-of-line quality check, we can help with sensors that are off-the-shelf or customdesigned for the specific application.
Features and benefits of piezoelectric and strain gage force sensors.
Piezoelectric force sensors are well suited for measuring dynamic and quasi-static force. They feature high stiffness, fastresponse, and repeatable performance, permitting them to capture high frequencies and follow fast transient events such asimpacts. The high stiffness allows them to survive repetitive cycles without fatigue. Quasi-static applications may include slowacting press or mechanical linkage forces acting in a cyclic manner during a industrial production process. Strain gage force sensors, or load cells, are well suited for measuring slowly changing or static force. They possess DC responseand are appropriate for static applications. Fatigue rated versions are constructed of high-grade steel for surviving manyrepetitive cycles encountered during product durability testing. Strain gage load cells are not suitable for capturing frequenciesin excess of several hundred Hz. They are also typically larger than similarly ranged piezoelectric force sensors.
