Inside the Technology: How FPI’s TCD Analyzers Operate

FPI’s Thermal Conductivity Analyzers follow a streamlined process for reliable gas analysis:

Gas Sampling and Exposure: Process gas flows through a thermally isolated chamber, interacting with heated filaments or thermistors.
Thermal Response: Variations in gas conductivity alter filament temperature, shifting resistance in the Wheatstone bridge.
Signal Conversion: Digital processors translate resistance changes into concentration data, with algorithms compensating for pressure and temperature fluctuations.
Data Output: Real-time results feed to SCADA or cloud platforms, with visual dashboards for operator insights.

This robust workflow, illustrated in our interactive schematics, ensures uptime in continuous operations.
