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 (10 )Vm/N FEATURES constant g33 -330 Minimum Impedance: 1 M k31 12% Preferred Impedance: 10 M and higher Electromechanical Coupling Factor Output Voltage: 10 mV to 100V depending on Force k 14% t and Circuit Impedance 380 for 2, Storage Temperature: -40C to +70C -40F to 60F C Capacitance pF/cm 1KHz 28m Operating Temperature: 0C to +70C 32F to 160F 9 2 Y Youngs Modulus 2-4 10 N/m APPLICATIONS 3 10 m/s in thickness V0 Speed of Sound 2.2 direction Sensing Direct Contact Force Recording Time of an Event Counting Number of Impact Events Measuring Impact Related Events SENSOR SOLUTIONS /// DT Series Rev 1 9/2015 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 1000 Lucas Way Hauert 13 F1.6-4D, Tian An Development Compound Hampton, VA 23666 44227 Dortmund ShenZhen, China 518048 Sales and Customer Service Germany Sales and Customer Service Tel: +1-800-745-8008 or Sales and Customer Service Tel: +86 755 8330 1004 +1-757-766-1500 Tel: +49 (0)231 9740 21 Technical Support Fax: +1-757-766-4297 Technical Support Email: piezo meas-spec.com Technical Support Tel: +49 (0)6074 862822 Email: piezo meas-spec.com Email: piezoeurope meas-spec.com TE.com/sensorsolutions Measurement Specialties, Inc., a TE Connectivity company.
