These can be fabricated into simple transducers, or for use as full size sheets for applications such as speakers. Piezo Film is available in different thicknesses. Thinner films (28 and 52 m) are the most common, due to their higher capacitance and good mechanical qualities. Thicker film (110 m) is used where maximum robustness is needed, or if the sensor is being used in a thickness mode (d33) application. el change NiCu Alloy to Cu with Ni, which has good conductivity and is resistant to oxidation. Other metallizations such as gold are available on a custom basis with a set up fee. For the sputtered metallized film, there is no border. These are only general rules, and a discussion with our applications engineers will help you to make the best choice for your specific application. Metallization options include a compliant silver ink as well as sputtered metallization. The silver ink is best for applications where mechanical stress is being applied. Silver ink lends itself to custom metallization patterns for easy lead attachment. Thin sputtered metallization is brittle and used where signal to noise requirements dictate very low mass loading by the electrodes. Our standard sputtered metallization is 700D of copper covered with 100D of nick- DIMENSIONS in INCHES (mm) Description A Film B Electrode C Film D Electrode t (m) Metallization Part Number 28 m piezo film 8.00 (203) 8.00 (190) 11.00 (280) 11.00 (267) 28 Cu-Ni 1-1003702-7 28 m piezo film 8.00 (203) 7.50 (190) 5.50 (140) 5.00 (127) 40 Silver Ink 1-1004347-0 28 m piezo film 8.00 (203) 7.50 (190) 11.00 (280) 10.50 (267) 40 Silver Ink 1-1004346-0 52 m piezo film 8.00 (203) 8.00 (190) 11.00 (280) 11.00 (267) 52 Cu-Ni 2-1003702-7 52 m piezo film 8.00 (203) 7.50 (190) 5.50 (140) 5.00 (127) 64 Silver Ink 2-1004347-0 52 m piezo film 8.00 (203) 7.50 (190) 11.00 (280) 10.50 (267) 64 Silver Ink 2-1004346-0 110 m piezo film 8.00 (203) 8.00 (190) 11.00 (280) 11.00 (267) 110 Cu-Ni 3-1003702-7 110 m piezo film 8.00 (203) 7.50 (190) 5.50 (140) 5.00 (127) 122 Silver Ink 3-1004347-0 110 m piezo film 8.00 (203) 7.50 (190) 11.00 (280) 10.50 (267) 122 Silver Ink 3-1004346-0 Effective: August 1st, 2008 Please contact the factory for pricing and custom part quotations. 800.745.8008 MEASUREMENT SPECIALTIES, INC. www.meas-spec.com (757) 766-1500 Fax (757) 766-4297 3 DT Series Elements The DT series of piezo film sensors elements are rectangular elements of piezo film with silver ink screen printed electrodes. They are available in a variety of different sizes and thicknesses. DT elements are supplied with a thin urethane coating over the active sensor area; the lead attachment legs are free of the insulating urethane coating. The DT film element produces more than 10 millivolts per microstrain, about 60 dB higher than the voltage output of a foil strain gage. The capacitance is proportional to the area and inversely proportional to the thickness of the element. C D The DT series sensors are the simplest form of piezo film sensors, used primarily as dynamic strain gages and contact microphones for vibration or impact detection. These are available without any leads for those applications where the customer wants to make his own lead attachment. They can be readily adhered to a surface with double-sided tape or epoxy. Lead attachment can be achieved by compressive clamping, crimps, eyelets, conductive epoxy or low temperature solders. t t Metallization A B Protective Coating Piezo Film DIMENSIONS in INCHES (mm) Description A Film B Electrode C Film D Electrode t (m) Cap (nF) Part Number DT1-028K .64 (16) .484 (12) 1.63 (41) 1.19 (30) 40 1.38 1-1002608-0 DT1-052K .64 (16) .484 (12) 1.63 (41) 1.19 (30) 64 .740 2-1002608-0 DT2-028K .64 (16) .484 (12) 2.86 (73) 2.42 (62) 40 2.78 1-1002145-0 DT2-052K .64 (16) .484 (12) 2.86 (73) 2.42 (62) 64 1.44 2-1002145-0 DT4-028K .86 (22) .740 (19) 6.72 (171) 6.13 (156) 40 11.00 1-1002149-0 DT4-052K .86 (22) .740 (19) 6.72 (171) 6.13 (156) 64 5.70 2-1002149-0 Effective: August 1st, 2008 Please contact the factory for pricing and custom part quotations. 800.745.8008 MEASUREMENT SPECIALTIES, INC. www.meas-spec.com (757) 766-1500 Fax (757) 766-4297 4 DT Series Elements with Lead Attachment The DT series of piezo film sensors elements are rectangular elements of piezo film with silver ink screen printed electrodes. They are available in a variety of different sizes and thicknesses. Lead attachment is accomplished using a riveted lug going to 12" (300 mm) of 28 AWG wire. The DT film element produces more then 10 millivolts per micro-strain. The capacitance is proportional to the area and inversely proportional to the thickness of the element.

Typically, a 0.005" (125m) polyester layer is laminated to a 28 m or 52m piezo film element. When used in a `bending' mode, laminated film elements develop much higher voltage output when flexed than a non-laminated DT elements series. The neutral axis is in the laminate instead of in the film so the film is strained more when flexed. The capacitance is proportional to the area and inversely proportional to the thickness of the element. Piezo film sensors LDT elements are available in a variety of lead attachment options. For significantly increased sensitivity, the LDTM-028K (M-Mass) combines an LDT0-028K form factor with the addition of a 0.72 gram round mass. The LDT1, 2 and 4 have 12" of 26 gauge twisted pair wire. The LDT0-028K and LDTM-028K with solder tabs can be soldered directly to a PCB with a reasonable level of care. Piezo film cannot withstand high temperatures (>80C), and therefore soldering of the pins to a PCB must be done quickly. A heatsink clamped to the interface area between the film and the crimps will take the heat away from the film. Pre-tin the PCB and then quickly solder the sensor to the board. Do not allow the soldering iron to touch the film, and do not use a dwell time of over 5 seconds on the pins. Low temperature solders can also be used. used to control variations of boundary conditions in production. Applications for this include beam-type vibration sensors for vehicle alarms and solid state switches for counters and momentary closure type switches.

These are rectangle elements of piezo film with silver ink screen printed electrodes. Rather than making the lead attachment near the sensor, the piezo polymer tail extends from the active sensor area as flex circuit material with offset traces. This gives a very flat, flexible lead, with a connector at the end. The FDT elements are available in a variety of different sizes and thicknesses. They are available without a laminate (FDT), with a laminated (0.005" mylar) on one side (FLDT) or with tape release layer adhesive (FDT with adh) in the sensor area. The connector pins on the FDT sensors can be directly soldered to a PCB with a reasonable level of care. This component cannot withstand high temperatures (> 80C), and therefore coldering of the pins to a PCB must be done quickly. A heatsink clamped to the interface area between the film and the crimps will take the heat away from the film. Pre-tin the pins and then quickly solder them to the board. Do not allow the soldering iron to touch the film, and do not use a dwell time of over 5 seconds on the pins. Low temperature solder can also be used.

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, given a self-shielding of the transducer area. This is important in applications in high EMI environments. C D t B A 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. Coax Cable Folded Over Construction Protective Coating 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 or a signal analyzer.

Piezo film's capabilities to generate a high voltage output under bending strain, combined with its rugged form factor, make it an ideal candidate for solid state impact switches. Rather than using a switch contact closure, the piezo film generates a pulse which is detected by electronics. Although many of the DT's, LDT's and FLDT's supplied by MEAS are used for switch applications, it is sometimes convenient to have a switch with integrated electronics. Thus the SW100 provides a single digital pulse that is ideal for triggering digital circuits and signal processing. The imperviousness, elasticity and reliability of the PFS element, along with the noise rejection characteristics of the circuit, combine to provide the SW100 with features that suit applications demanding consistent, reliable performance throughout tens of millions of switching cycles. Custom options are available to fit specific customer applications. For more information on the SW100, please call one of our applications engineers. The SW100 is an ideal configuration for impact detection and momentary switch applications. A direct contact force on the tip of the stainless steel cantilever beam of the SW100 induces strain on the laminated Piezo Film Sensor (PFS) element. With dynamic strain, the PFS element generates an output that activates a built-in, normally-open circuit.

Designed as a coax cable, the piezo polymer is the "dielectric" between the center core and the outer braid. When the cable is compressed or stretched, a charge or voltage is generated proportional to the stress. Detailed specification sheets are available on our website: www.meas-spec.com. Continuous lengths of piezo cable is available in a variety of different gages and construction formats. As a standard product, it is offered as a 20 AWG center core with a polyethylene outer jacket. Piezo cable has a number of advantages in certain applications. Due to its coaxial design, the cable is selfshielded, allowing its use in a high EMI environment. The piezo cable can be spliced to passive coax, using standard coax splice techniques. It is extremely rugged, and will stand up to heavy loads as with truck axle counting. Its linear format makes it ideal for monitoring large areas. Two versions of the piezo cable are offered, copolymer and spiral. 20AWG Cable-Spiral Wrap 20AWG Cable-Copolymer DIMENSIONS in INCHES (mm) Dimensions Description Center Core Outside Dia.

Pins are designed for easy installation and are solderable. Horizontal and vertical mounting options are offered. The active sensor area is shielded for improved RFI/EMI rejection. Rugged, flexible PVDF sensing element withstands high shock overload. Sensor has excellent linearity and dynamic range, and may be used for detecting either continuous vibration or impacts. The mass may be modified to obtain alternative frequency response and sensitivity selection (consult factory). The sensor may be used to detect either continuous or impulsive vibration or impacts. For excitation frequencies below the resonant frequency of the sensor, the device produces a linear output governed by the "baseline" sensitivity. The sensitivity at resonance is significantly higher. Impacts containing highfrequency components will excite the resonance fre-quency, as shown in the plot above (response of MiniSense 100 to a single half-sine impulse at 100 Hz, of amplitude 0.9 g). The ability of the sensor to detect low frequency motion is strongly influenced by the external electrical circuit. The MiniSense 100 acts as a cantilever-beam accelerometer. When the beam is mounted horizontally, acceleration in the vertical plane creates bending in the beam, due to the inertia of the mass at the tip of the beam. Strain in the beam creates a piezoelectric response, which may be detected as a charge or voltage output across the electrodes of the sensor.
