Through-hole and donut force sensors measure force while leaving a central opening for bolts, rods, or shafts. This guide compares strain gauge and piezoelectric designs, load washer and flange mounting arrangements, and their uses in clamping, presses, and research fixtures. It explains how to select dimensions and capacity, evaluate accuracy at working loads, manage preload and force shunts, connect signal conditioning to a PLC or data acquisition system, and verify the installed measurement chain. It also identifies checks needed before replacing an existing sensor.
This guide explains what a multi-axis force sensor measures and when to choose a 3-axis force sensor, a 6-axis force/torque sensor, or an axial force and torque sensor. It shows how tool offsets create bending moments and why combined loading limits matter when sizing a sensor. Engineers can use the guide to compare measurement error and crosstalk, check mounting and data acquisition compatibility, and verify channel direction and response with known loads after installation. It also covers practical checks for replacing an existing sensor.
Understand how a force sensor works and how to select a design for equipment integration or research testing. This guide compares miniature and button, through-hole and donut, inline tension and compression, and column force sensors. It explains strain gauge and piezoelectric principles, force range, preload, accuracy, mounting, and PLC or DAQ connections. Practical FIBOS product examples show why loading surfaces and mechanical interfaces matter. Readers also learn how to distinguish zeroing from calibration and verify the complete force measurement chain under installed conditions.
