A/161

A/161

Product catalog summary
Overview: The A/161, A/161-1, A/162, A/162-1, and A/163-1 series are high shock IEPE accelerometers designed for applications requiring measurement of high amplitude, short duration transient events such as pyrotechnic shocks or high energy impacts. These accelerometers are made from stainless steel and can measure up to 50,000g.
Specifications:
  • Sensitivity: 0.1/0.2/0.5 mV/g ±10%
  • Weight: 8/10/16 gm
  • Maximum Temperature: 121°C
  • Frequency Response: 1Hz to 15kHz
  • Resonant Frequency: ≥40 kHz
  • Temperature Range: -40 to +121°C
  • Excitation Voltage: +18 to +28 V
  • Excitation Current: 2 - 20 mA
  • Output Impedance: <150 Ω
  • Output Bias Voltage: +8 - +12 VDC
Design Features: The A/16X range includes built-in filters to ensure linear response across a wide frequency band and can withstand physical shock limits up to 60,000g, depending on the version. This is crucial for handling the unpredictable nature of pyrotechnic events.
Applications: These accelerometers are suitable for various high transient acceleration measurements, including pile driver monitoring, simulated pyroshock events, recoil and penetration, impact press monitoring, explosive studies, and armor piercing.
Model Variations:
  • A/161 – M5 Microdot connector
  • A/161-1 – Integral Cable
  • A/162 – M5 Microdot connector
  • A/162-1 – Integral cable
  • A/163-1 – Integral cable
Key Parameters:
  • Model A/161 and A/162 have a physical shock limit of 30,000g, while A/162-1 and A/163-1 can withstand up to 50,000g and 60,000g respectively.
  • All models have a resolution of 0.3grms and horizontal sensitivity of ≤7%.
  • Installation varies with M5 or M6 connectors and integral cables depending on the model.

A/161-1

A/161, A/161-1, A/162, A/162-1, A/163-1 Series High Shock IEPE Accelerometers 0.1/0.2/0.5 mV/g ±10% 8/10/16gm wt. 121 °C Max Developed for demanding applications requiring the measurement of high amplitude, short duration transient events such as pyrotechnic shock or high energy impacts, the A/16X range of stainless steel IEPE accelerometers have a range from 10,000g up to 50,000g 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 the standard sensor and hybrid electronics used in the IEPE accelerometers. To overcome these issues the A/16X range has in built filters which ensure the response is linear across a wide frequency band up to (1Hz to 15kHz) and up to a peak amplitude measurement of 50,000g. The A/16X range is also designed to withstand over testing, the accelerometers have a physical built in protection up to 60,000g, (depending on version) this is necessary due to the highly variable and sometimes unpredictable nature of pyrotechnic events.
