Piezosensor8/27/2023 ![]() Other piezo film devices such as SDT1-028K are available and are shielded. Metallized tapes can be used to cover the sensor but these may impede motion and subsequent output. If shielding is required, the sensor can be enclosed in a proper environment. The LDT1-028K device is unshielded by design. Otherwise signal cancellation can result, minimizing signal. It is essential that the film not be in the neutral axis of the beam. The SDT1-028K is a fully shielded form of the LDT1-028K.īending: A cantilever arrangement will allow the piezo element to be deflected and this can be used to detect a striking object when the element is flexed. The direct adherence of the LDT1-028K to the vibrating body can detect vibration, but another piezo film sensor configuration (SDT1-028K) is available and designed for this application. ![]() ![]() Add a small weight to the end of the sensor if the greater Vibration and Motion Sensing: Mount the element in a cantilever arrangement, allowing the Apply the force (such a finger touch or hammer blow) to the sensor area. Sensing direct contact force, Recording time of an event, Counting number of impact events, Measuring impact-related events, Sensing vibration using cantilevered beam, Wakeup switch, Motion detection.ĭirect Impact Sensing: Using an adhesive (such as double sided tape) adhere the sensor area to a pliable pad to absorb impact with the full length protective laminate on the impact face. Output voltage: 10mV-100V depending on force and circuit impedance.The dual wire lead attached to the sensor allows a circuit or monitoring device to process the signal. The piezo film element is laminate to a sheet of polyester (Mylar), and produces a useable electrical signal output when forces are applied to the sensing area. The LDT1-028K is a multi-purpose, piezoelectric sensor for detecting physical phenomena such as vibration or impact. Piezo Sensor - LDT1-028K Lead Attachments
