Bestech Sensors and Teaching Equipment offer high performance sensing and monitoring systems for applications in aerospace, energy, defence, industrial and laboratory testing as well as automotive, transportation and agricultural industries.

The Piezoresistive Accelerometers are designed for high frequency and high g shock measurement

  • Versatile due to their frequency and dynamic range capabilities
  • Widely used in automobile safety testing including anti-lock braking system, safety air-bags and traction control system
  • Suitable for use in weapon testing and seismic measurements
  • Converts mechanical strain to a DC output voltage

Piezoelectric Accelerometers are made of piezoceramics, single crystals or, for high temperature operation, tourmaline or lithium niobate featuring high frequency and temperature range whilst remaining low weight in package.

Ideal for measuring absolute vibration and used in scientific and industrial applications as predictive maintenance, aerospace, automotive, medical and process control

  • Extremely wide dynamic range, low output of noise
  • Excellent linearity over dynamic range
  • Acceleration signal can be integrated to provide velocity and displacement
  • Highly sensitive with a wide frequency range
  • Self-generating with no external power required

IEPE/Voltage mode accelerometers feature an integral electronic impedance converter eliminating the need for an external charge amplifier

  • Operating temperature range of -55 °C to 288°C
  • Special purpose models are available for extreme environments of –269°C to as high as 760°C
  • Ability to drive long cables with minimal distortion and noise pick-up

Variable Capacitance (VC) Accelerometers typically include mechanical components and detect interface circuit

  • Manufactured using silicon microfabrication
  • Possess high sensitivity, low power consumption and excellent linearity
  • Units are independent of temperature
  • Highly accurate and rugged
  • Available in eight standard ranges of 2g to 400g with a wide range of full-scale sensitives

Piezoelectric Microphones are transducers used to convert acoustic sound into an electric signal. The microphones are used with high frequency sound finding applications in noise, vibration and harshness testing, pass-by noise testing, environmental noise, appliance noise evaluation as well as a number of other testing applications.

Piezoelectric Microphones offer easy plug-in installation and insensitivity to altitude changes and ambient vibration

  • Directly compatible with Isotron (IEPE) signal conditioning
  • Lower overall per channel measurement cost
  • Simple construction and repairable diaphragm
  • Low profile surface microphone, ideal for measuring wind-induced noise on ground and airborne vehicles
