High output together with minimal susceptibility to strain induced error extends the measurement range of the A/21 down to the 10-5g, 10-1Hz region.

The A/21 application area thus includes low level, low frequency dynamic analysis as occurs in the civil and marine engineering fields.

The KONIC sensing element, all welded construction, and total absence of epoxies and soldered connections maximises sensitivity /mass ratio (3pC/gm), reliability, and operating temperature.


  • Close tolerance output
  • Corrosion resistant case materials
  • Wideband temperature calibration -50/+250°C
  • Hermetic TNC top entry connector verions, with or without cables, can be pressure tested at sustained levels of up to 100 bar
