Compression load cell 9313AA1

beam typesingle-axispiezoelectric

Product overview
This miniature piezoelectric compression force sensor (model 9313AA1) is designed for dynamic and quasistatic force measurement in compact industrial installations. The sensor is preloaded and supplied with practical mounting adaptation options for immediate integration. Its piezoelectric charge output requires a measuring amplifier or charge converter for conversion to a process signal. The square sensor body and axial threaded bores at both ends enable flexible axial force introduction and simplify special mounting situations. Tensile forces up to 10% of the compression range can be measured (not calibrated) and are typically used to detect tool withdrawal forces after press-fitting.

Main features

• Preloaded, calibrated force transducer ready for immediate use
• Calibrated Fz ranges: 0 … 0.05 kN; 0 … 0.5 kN; 0 … 5 kN
• Sensitivity: ≈ −10 pC/N
• Compact dimensions DxH: 13 x 10 mm; weight: 10 g (without cable)

Description
The 9313AA1 is optimised for installation where space is limited and dynamic or quasistatic force signals must be acquired. Charge output requires a downstream measuring amplifier or charge converter to produce a stable process signal. Axial force can be introduced from either end; the square housing and axial threaded bores facilitate secure fixing and adaptation to fixtures.

How it works
The piezoelectric crystal inside the sensor generates an electric charge proportional to the applied axial force. A measuring amplifier or charge converter downstream converts this charge into an evaluable process signal compatible with test or production equipment.
