Five families. One matched measurement chain.
Choose the mechanical form first, then check pulse duration, force direction and the input your DAQ or PLC actually accepts.

The installation is part of the sensor
Preload, force shunt and installed sensitivity
A center bolt keeps the quartz ring compressed, but also bypasses part of the incremental force. Select preload from the exact sensor and hardware instructions. Around 20% of nominal force appears in some manufacturer guidance; it is not a universal QPF setting.
Check total compression with preload, tensile unloading, contact faces and bolt stiffness. Calibrate the installed assembly. Torque alone is not a direct measurement of preload.

Charge and IEPE need different conditioning.
Charge output · pC/N
A high-impedance quartz signal needs a charge amplifier, clean connectors and qualified low-noise cable. Review temperature and drift at the assembly level.
Plan a charge measurement chain →IEPE output · mV/N
Built-in electronics need constant-current excitation with adequate compliance voltage. Cable capacitance and current still matter for large fast signals.
