IEPE Piezo Force Sensors

Specify a compact quartz piezoelectric force sensor for dynamic compression, controlled tension and laboratory force input. Start with the force pulse and your existing acquisition channel.

50 N–45 kN compression requests · IEPE voltage output. Selection envelope; confirm the exact model.

Before selecting QPF-208

Check force, mounting and signal limits together

Mounting

Tapped upper/lower interfaces, impact cap and stud options; exact threads and envelope require a release drawing.

Direction

Compression ranges are separate from tensile ratings. Planned tension envelope extends to 2.2 kN, subject to model confirmation.

Electrical chain

Confirm constant current, supply compliance voltage, sensor bias, usable voltage swing and DAQ coupling. Never apply a raw voltage supply directly.

Long cables

Cable capacitance, excitation current and signal slope can limit high-frequency output even with IEPE low-impedance electronics.

Release the measurement chain with evidence

Request a configuration-specific drawing and calibration record. Confirm rated load, direction, preload, sensitivity, polarity, flat response band, thermal range and overload limits. Discuss the required acceptance test before freezing the order.

Can this measure a static load continuously?

Piezoelectric force measurement decays with system leakage and time constant. Share the cycle and allowed drift; for continuous dead-weight measurement use a suitable static sensing method.

Can I use an existing cable and conditioner?

Yes, if the full chain is verified for the chosen output, sensitivity, current or charge input, signal range, bandwidth, cable construction and connector. QPF accessory choices are optional.

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.

Describe the event.
We’ll review the chain.

Include the peak force and pulse duration, your mounting space and existing DAQ. For replacements, add the complete original model and sensitivity.
