• Preloaded and calibrated force transducer, ready to measure immediately • Sensitivity: ≈ –10 pC/N • Dimensions DxH: 13x10 mm This lightweight miniature compression force sensor is particularly suitable for measuring dynamic forces and also quasistatic forces. Preloaded and provided with practical adaptation options, the sensor is ready for immediate use. The Press Force load cell is based on the piezoelectric measuring principle. The force acting on the crystal element produces a proportional electric charge at the signal output. A measuring amplifier connected downstream to the sensor converts this charge into a process signal which can be evaluated. The particularly square shape of the sensor body and the force introduction at both ends via axial threaded bores bring advantages in special mounting situations. Tensile forces up to 10 % of the compression force range are measured. These ranges are not calibrated. However, they are often used for the detection of tool withdrawal forces, for example after press fitting processes.
