Vibrating Wire Instruments – BluWire

BluWire is a 4 instrument Vibrating Wire (VW) interface that can be connected to either a wired (RS485) or wireless interface (Bluetooth 5). The device will interrogate all 4 ports and return a single output string with the resonant frequency of connected instruments in Hertz. The interrogation algorithm is a robust swept frequency over a user defined range. The resolution of the output signal is 0.1Hz and the accuracy is typically 0.025%FS.


  • Excitation range (1kHz-10kHz) – user definable
  • Resolution: 0.1Hz
  • Frequency Accuracy: 50ppm
  • Temperature: -20–85C
