Model 2510 Piezoelectric microphone - Endevco

Model 2510Piezoelectric microphoneFeatures• Requires no external power• Hermetically sealed• Vibration compensated• Operational range, 100 to >180 dB SPL• High intensity acoustic measurement• High temperature to +500°F (+260°C)DescriptionThe Endevco ® Model 2510 Microphone measureshigh intensity acoustic noise and very low pressurefluctuations. The rugged, hermetically sealedconstruction and extremely wide temperature range-67°F to +500°F (-55°C to +260°C) make this transducerextremely useful over a wide range of environmentalconditions, including insensitivity to altitude changes,and the transducer has vibration compensationincorporated into the sensing element. The microphoneis a self-generating device that requires no externalpower source for operation.The Model 2510 features a very thick diaphragm thatprevents puncturing or damage due to particle impact,accidental mishandling, or high pressure pulses.Insulation between the transducer and mounting surfaceprevents data-degrading ground loops. The Model 2510is intended primarily to operate into charge amplifiers.Long cables may be used between the transducer andcharge convertor without affecting charge sensitivity.Although the basic design is directed toward maximizingcharge characteristics, the Model 2510 also givesexcellent results when operated into voltage amplifiers..50(12.7).25(6.35)1TORQUE MTG BRACKETSCREW 5-7 IN-LB.Endevco signal conditioner Models 133, 2775A, 2721B or 2680 are recommended foruse with this high impedance microphone.1.000(25.40)11.360 (34.54)1.300 (33.02)1.125(28.58).50(12.7)1.50(38.1).195(4.95)1.255 (31.87)1.245 (31.62).125(3.18).815(20.70)1.50(38.1)DIA.dB DEVIATIONTYPICAL AMPLITUDE RESPONSE543210-1-2-3-4-51 10 100 1000 10000FREQUENCY IN HERTZTYPICAL TEMPERATURE RESPONSE2015.435 (11.05).345 (8.76).205(5.21).745(18.92)DIA..25(6.4)MATES WITH ENDEVCO3000 SERIES CABLESWITH 10-32 UNF-2ACONNECTOR% DEVIATION1050-5-10UNIT IDENTIFICATION .157 (4.14).151 (3.84)STANDARD TOLERANCEINCHES (MILLIMETERS).XX = +/- .02 (.X = +/- .5).XXX = +/- .010 (.XX = +/- .25)DIA. 2PL-15-20-100 0 100 200 300 400 500TEMPERATURE °F (°C)cmyk
