Piezoelectric Accelerometer Sensors With Flexible, Integral Cable

Posted by Industry News on

PCB Piezotronics - Teardrop ICP Shock Accelerometers with Flexible, Integral Cable

PCB Piezotronics has released two miniature piezoelectric accelerometers. They are 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 cable design enable the sensor to survive 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 are designed to provide 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.


  • Two measurement ranges ±5,000g, ± 20,000g
  • Extremely small size minimizes mass loading
  • High overload shock limit allowing higher amplitudes without damage
  • Wide frequency range for broader testing capabilities
  • Flexible integral cable for easy routing in tight spaces


  • Environmental Stress Screening (ESS)
  • Electronics and circuit board qualification
  • Mobile electronics drop testing
  • Small component shock testing

PiCAN with GPS - Gyro - Accelerometer CAN-Bus Board for Raspberry Pi 3

The PiCAN GPS board provides CAN-Bus and GPS capability for the Raspberry Pi. It uses the Microchip MCP2515 CAN controller. CAN connections are made via 4 way screw terminal plugs. The GPS is provided by a 66-channels MTK3339 chipset module. An onboard battery holder exists for a CR1225 cell. The backup power is for the real time clock and helps reduce startup times. The GPS module has a built-in patch antenna but an external active antenna can also be used via uFL connector.

The MPU-6050 provides six axis gyro and accelerometer with an onboard Digital Motion Processor (DMPTM) capable of processing complex 9-axis MotionFusion algorithms. It does away with the cross-axis alignment problems that can creep up on discrete parts.

There is an easy-to-install SocketCAN driver, and programming can be accomplished using C or Python.
