SDT Shielded piezo sensors

The “S” in SDT stands for “Shielded Sensor.”
SDT1 Piezo Film Sensors consist of a rectangular
element of Piezo film together with a molded plastic
housing and 18” of coaxial cable. The film element, screen
printed with silver ink, is folded over on itself, providing
self-shielding of the transducer area. This is important in
applications in high EMI environments.

The SDT1 can be adhered to other surfaces using
double sided adhesives, epoxy or cyanoacrylate (super
glue). Care should be taken if the sensor is to be removed,
as the double-side adhesive can peel the metallization
from the film.

When adhered to a surface in this manner, the
SDT1 is an excellent contact microphone or dynamic
strain gage. The output from the SDT1 can input directly to
an oscilloscope (10 MΩ preferred input impedance) or a
signal analyzer.
