VICI TCD-3 is a dual filament, stand-alone thermal conductivity detector consisting of the detector housing and separate controller. However, the analog controls of the TCD-2 are replaced with full digital control implemented via a user interface or command console commands. Thermal stability is maintained in the detector to within 0.010°C, producing a stable, low-noise signal.
The TCD-3 controller generates an independent analog output signal for each of the detector filaments. In additional, a referenced analog output signal is generated by subtracting the output signal of one filament channel from the other. Each of these three output signals is provided in two full-scale spans: a ±1 volt scale and a ±10 volt scale.
