SV 38

IEPE Whole-Body Seat Accelerometer

SV 38 IEPE Whole-Body Seat Accelerometeris based on MEMS transducers. It is dedicated for Human Vibration measurements performed according to ISO 2631-1  with SVAN 958A four channel analyser. With optional SC 39S cable it is possible to connect SV 38 transducer to any vibration meter/analyser with IEPE inputs by the means of three separate BNC connectors. Calibration can be performed using dedicated adapter SA 38 (option).

Features

  • Meets ISO 8041 and ISO 2631
  • IEPE / ICP powering
  • Low price
  • Dedicated to SVAN 958 and SVAN 958A
