Electronic Stethoscope ES10i / ES11

Our electronic stethoscope sets ES10i or ES11 consist of a monitoring amplifier, a directional microphone, a headphone and a case. The AV11i and AV14 monitoring amplifiers are designed primarily for monitoring airborne noise and structure-borne noise via headphones to be connected to the output.

USES:

  • quick and exact sound location of disturbing sources e.g. in the filed of development and maintenance of vehicles and machinery
  • Preamplifier for analyzers

Monitoring Amplifier

There are two variants available:

AV11i monitoring probe

AV11i

  • included in set ES10i
  • IEPE Input channel (Microphone or acceleration sensor)
  • Measuring output
  • Adjustable Headphones output
  • Input amplifier: 0 dB and +20 dB selectable
  • Switchable octave filter, 9 frequencies
  • Switchable third octave filter, 25 frequencies
  • Display with backlight

  • Robust aluminum cabinet
AV14 Monitor Amplifier and Charge Amplifier without filter

AV14

  • included in set ES11
  • one input channel ( Direct or Microphone or Charge)
  • one measuring output
  • adjustable Headphones output
  • internal rechargeable battery for portability
  • robust aluminum cabinet

Monitoring amplifier AV11i / AV14

The 1-channel monitor amplifier AV11i and iAV14 are handheld, battery-driven instruments, which has been constructed mainly to monitor acoustic and vibration signals with headphones.

AV11i offers you many possibilities to locate disturbance sources. AV11i offers you many possibilities to locate disturbance sources. It has an IEPE measuring input for microphone or piezoelectric accelerometer. The measuring signal can be weighted with the switchable octave filter (9 frequencies) or third octave filter (25 frequencies).  So you can detect the exact frequencies of the disturbance source.

The AV14 has an input to which an MI10 microphone or a piezoelectric accelerometer can be connected.

At the output socket of the two amplifier variants you get a voltage proportional to the acceleration or sound pressure independent of the amplification of the headphone amplifier. So the instrument can be used as a front end for analyzers.

The AV11i and AV14 are designed for mobile use. The power is supplied by batteries. Thanks to the robust aluminum housing, both amplifiers can also be used in a robust environment.
