DT SERIES ELEMENTS WITH LEAD ATTACHMENT SPECIFICATIONS Piezoelectric film sensor AC Coupled Silver Ink Electrodes Protective Coating over Electrodes Lead Wires Attached with Rivets. 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 TYPICAL PIEZO FILM PROPERTIES accomplished using a riveted lug going to 12 (300 mm) of 28 AWG wire. The DT film element produces more than 10 Symbol Parameter PVDF Units millivolts per micro-strain. The capacitance is proportional to the area and inversely proportional to the t Thickness 28, 52 m thickness of the element. d 23 31 The DT elements are supplied with a thin Piezo Strain -12 (10 )C/N protective coating over the active electrode area to Constant d -33 33 prevent oxidation to the top surface of the silver ink. g31 216 Piezo Stress -3 FEATURES (10 )Vm/N constant g33 -330 Minimum Impedance: 1 M Preferred Impedance: 10 M and higher k31 12% Electromechanical Output Voltage: 10 mV to 100V depending on Force Coupling Factor k 14% t and Circuit Impedance Storage Temperature: -40C to +70C -40F to 60F 380 for 2, C Capacitance pF/cm 1KHz Operating Temperature: 0C to +70C 32F to 160F 28m 9 2 Y Youngs Modulus 2-4 10 N/m APPLICATIONS 3 10 m/s in thickness Sensing Direct Contact Force V0 Speed of Sound 2.2 direction Recording Time of an Event Counting Number of Impact Events Measuring Impact Related Events SENSOR SOLUTIONS /// DT Series Rev 1 07/2017 Page 1 DT SERIES ELEMENTS WITH LEAD ATTACHMENT DIMENSIONS and PART NUMBERS Dimensions in inches (mm) Total Film A B C D Cap Model Number Part Number Thickness Thickness Film Electrode Film Electrode (nF) ( m ) 28 m .64 (16) .484 (12) 1.63 (41) 1.19 (30) 40 1.38 DT1-028K/L w/rivets 1-1002908-0 52 m DT1-052K/L w/rivets 2-1002908-0 .64 (16) .484 (12) 1.63 (41) 1.19 (30) 64 .740 28 m DT2-028K/L w/rivets 1-1003744-0 .64 (16) .484 (12) 2.86 (73) 2.42 (62) 40 2.78 52 m .64 (16) .484 (12) 2.86 (73) 2.42 (62) 64 1.44 DT2-052K/L w/rivets 2-1003744-0 28 m DT4-028K/L w/rivets 1-1002150-0 .86 (22) .740 (19) 6.72 (171) 6.72 (171) 40 11.00 52 m .86 (22) .740 (19) 6.72 (171) 6.72 (171) 64 5.70 DT4-052K/L w/rivets 2-1002150-0 NORTH AMERICA EUROPE ASIA Measurement Specialties, Inc., MEAS Deutschland GmbH Measurement Specialties (China), Ltd., a TE Connectivity Company a TE Connectivity Company a TE Connectivity Company Tel: +1-800-522-6752 Tel: +49-800-440-5100 Tel: +86 0400-820-6015 Email: customercare.dtmd te.com Email: customercare.dtmd te.com Email: customercare.chdu te.com TE.com/sensorsolutions Measurement Specialties, Inc., a TE Connectivity company.
