Q.series - DC or Carrier Frequency

Depending on the application requirements, both DC and Carrier Frequency (CF) excitation methods come with their pros and cons.

This is why Q.series provides the bridge measuring module A106 that suites for both:

DC excitation
2.5 VDC or 5 VDC
Full, half, and quarter bridges
Sampling rate: 10 kHz, band width: 1 kHz

Carrier frequency excitation 600 Hz
2.5 Vrms or 5 Vrms
Full, half, and quarter bridges
Sampling rate: 10 kHz, band width: 100 Hz

Carrier frequency excitation 4.8 kHz
2.5 Vrms or 5 Vrms
Full, half, and quarter bridges, inductive bridges, LVDT, RVDT
Sampling rate: 10 kHz, band width: 1 kHz

Both channels can be configured independently from each other, are galvanically isolated, and each provide an analog output.

Furthermore, with A101 and A102 there are DC strain gauge inputs for up to 100 kHz available.
