Model 2510 - 1

Piezoelectric microphone Model 2510 • Requires no external power .25 (6.35) TORQUE MTG BRACKET SCREW 5-7 IN-LB. • Vibration compensated • Operational range, 100 to >180 dB SPL • High intensity acoustic measurement • High temperature to +500°F (+260°C) • Hermetically sealed TYPICAL TEMPERATURE RESPONSE UNIT IDENTIFICATION MATES WITH ENDEVCO 3000 SERIES CABLES WITH 10-32 UNF-2A CONNECTOR .157 (4.14) .151 (3.84) STANDARD TOLERANCE INCHES (MILLIMETERS) .XX = +/- .02 (.X = +/- .5) .XXX = +/- .010 (.XX = +/- .25) The Endevco® model 2510 microphone measures high intensity acoustic noise and very low pressure fluctuations. The rugged, hermetically sealed construction and extremely wide temperature range -67°F to +500°F (-55°C to +260°C) make this transducer extremely useful over a wide range of environmental conditions, including insensitivity to altitude changes, and the transducer has vibration compensation incorporated into the sensing element. The microphone is a self-generating device that requires no external power source for operation. The model 2510 features a very thick diaphragm that prevents puncturing or damage due to particle impact, accidental mishandling, or high pressure pulses. Insulation between the transducer and mounting surface prevents data-degrading ground loops. The model 2510 is intended primarily to operate into charge amplifiers. Long cables may be used between the transducer and charge convertor without affecting charge sensitivity. Although the basic design is directed toward maximizing charge characteristics, the model 2510 also gives excellent results when operated into voltage amplifiers. Endevco signal conditioner models 133, 2775A, 2721B or 2680 are recommended for use with this high impedance microphone.
