PCB has released two new miniature piezoelectric accelerometers. They are small, single axis ICP voltage output with measurement ranges of +/- 5,000 g (model 352A91) and +/- 20,000 g (model 352A92).
Both are in a similar package with low mass under 0.006 ounces (0.17 grams) and cover a broad frequency range of 1.2 to 10,000 Hz at +/- 5%. The accelerometer development concentrated on survivability under test in harsh environments.
The hermetically sealed titanium housing and flexible cable design enable the sensor to survive high overload shock (+/- 20,000 g peak) under thermal load up to +325°F (163°C). These features make them ideal for small component testing, environmental stress screening, and impact testing of electronic board assemblies.
Built-in ICP microelectronics provide a low noise, low impedance output signal for low transmission loss over long distances. PCB offers multiple signal conditioners to power these accelerometers but any ICP, current limiting signal conditioner or data acquisition system may be used. Models 352A91 and 352A92 are available for immediate shipment.
