The Endevco® model 2510M4A 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 2510M4A 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 2510M4A 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 2510M4A also gives excellent results when operated into voltage amplifiers. The model 2510M4A, with
electrical specifications identical to the basic model 2510, provides a special mounting for flush diaphragm
or other applications.
