Frequently Asked Questions

What is the recommended load impedance for the SDT1-028K sensor?

For optimal signal output and linearity, a load impedance of 10 MΩ is preferred. The sensor requires a minimum load impedance of 1 MΩ to function correctly. Connecting it directly to a standard oscilloscope or data acquisition system with a 1 MΩ input is typically suitable.

How should I mount the SDT1-028K piezo film sensor?

The sensor is designed for direct adhesive mounting onto the measurement surface. Use a thin layer of epoxy, cyanoacrylate (super glue), or a high-strength double-sided adhesive tape. Ensure the surface is clean and the adhesive covers the entire back of the thin film element for secure bonding and effective strain transfer.

What types of measurements is this sensor best suited for?

The SDT1-028K is engineered for dynamic measurements, not static forces. It excels at detecting vibration, impact, shock, and dynamic strain. Its wide frequency response makes it ideal for condition monitoring, acoustic emission detection, structural testing, and any application where high-frequency mechanical events need to be captured.

Does the sensor require external signal conditioning?

In many applications, the sensor's high output voltage allows direct connection to measurement equipment like oscilloscopes. For integration with lower-voltage ADCs or specific signal processing, a simple voltage follower or charge amplifier circuit may be required to match impedance and scale the signal appropriately.
