Available in sensitivities of 10 mV/g or 100 mV/g, the Endevco model 7253D is small and lightweight with a broad frequency response. Features include thru-hole mounting for 360? cable orientation, hermetically sealed titanium housing to protect against environmental contamination, and signal ground isolated from the mounting surface by a hard anodized insulator. Dimensions are low-profile at 0.70” x 0.70” x 0.375”, with a weight of <10 grams and operating temperature range of -67°F to +257°F (-55°C to +125°C).
Each axis utilizes an Endevco type P-8 shear piezoelectric sensing element in conjunction with a hybrid charge amplifier to provide a low-impedance output of 5 volt full scale in a two-wire IEPE system configuration. A constant current excitation of 2 to 20 mA is required for each axis, with the electrical connection made to each axis through a 4-pin connector.
Accessories included with the Endevco model 7253D include the 3027AM3-120 cable, 42883 mounting screw assembly and EHM488 wrench. Optional accessories include the models 123, 133, 2775B or 2793 signal conditioner.
The Endevco model 7253D offers a more compact form factor, lighter weight and wider frequency response compared to similar products available on the market today. And it is covered by a five-year comprehensive product warranty.
