With available ranges of 1, 2 and 5 psig, the Endevco® model 8510B offers a 300 mV full scale output and a range of at least 100 to 190 dB SPL, in a highly rugged four-active arm strain bridge design that is diffused in a sculptured silicon diaphragm. This miniature pressure microphone offers integral temperature compensation from -18°C to +93°C (0 to +200°F), ensuring measurement accuracy over its full temperature range with excellent linearity, even at three times over-range. Units also offer high resonance frequencies for accurate measurements over the full audio range, with five times minimum burst pressure and 20,000 g shock survivability. These technical attributes make the Endevco® model 8510B the industry’s highest performing pressure microphone of its kind on the market today.The new pressure microphone uses a 10-32 thread (metric threads available on custom order) for convenient mounting within space constrained environments, and also permits flush mounting on flat or contoured surfaces for boundary layer measurements in flight test, wind tunnels and engine inlet acoustic studies. A 30-inch integral cable is standard, with custom lengths available on request. For customer convenience, the model 8510B comes standard with a vent tube, which can be vented to the ambient atmosphere or connected to a standard reference manifold. Recommended for use with the Endevco® model 8510B are the model 136 three-channel signal conditioner, model 4430A signal conditioner, or the model 4990A (Oasis), all available from Meggitt Sensing Systems.
With its exceptional ruggedness, sensitivity and high output characteristics, the Endevco® model 8510B is ideal for use in applications such as blast testing, rocket motor acoustic studies, engine inlet acoustic studies, shock wave studies, chemical reactor monitoring and aerodynamic studies, among others.
