1-axis accelerometer A/162

IEPEshear

Available with an M5 Microdot connector (A/162) or a lightweight integral cable (A/162-1) the high shock accelerometer range use piezo-ceramic shear sensors with IEPE circuitry to allow direct connection to a wide range of acquisition hardware or to one of DJB Instruments range of Voltage source amplifiers. Aerospace Impact Testing Structural Testing Crash Testing Developed for demanding applications requiring the measurement of high amplitude and short duration transient events such as pyrotechnic shock or high energy impacts, the A/162 IEPE accelerometer has a range of ±25,000g and a sensitivity of 0.20mV/g (±10%). The design of our more standard accelerometers have limitations when used for shock applications, these can either be due to the short duration of the transient event or due to the high level of the shock amplitude, either of these elements can cause issues for a standard vibration sensor and the hybrid electronics used in the IEPE accelerometers. To overcome these issues the A/162 has in built filters; both electrical and mechanical which ensure the response is linear across a wide frequency band (1Hz to 15kHz), and up to a peak amplitude measurement of 25,000g. The A/162 is also designed to withstand over testing, the accelerometer can measure up to 25,000g, but features physical built in protection up to 50,000g. This is necessary due to the highly variable and sometimes unpredictable nature of pyrotechnic events. Other applications requiring high transient acceleration measurements can include: Pile Driver Monitoring Simulated Pyroshock Event Recoil and Penetration Impact Press Monitoring Explosive Studies Armour Piercing
