Gas analyzer for blending systems
The Thermal Conductivity Detector (TCD) gas analyzer was purpose developed for use with gas blending/mixing systems.
Lehigh Valley, PA - The Thermal Conductivity Detector (TCD) gas analyzer was purpose developed for use with gas blending/mixing systems. The TCD detects gas composition by measuring the difference in thermal conductivity between a reference gas stream and the sample gas stream. It uses a dual pass sampling system that allows it to be configured to analyze a number of gas combinations easily.
A five-way valve located in the front face of the analyzer simplifies the calibration process. Available output options include two or four relay output cards; RS-232, RS-485, and DeviceNet communication cards, and 1-10 V or 4-20 mA. Operating rate is 0.5 SCFH, minimum gas supply is 2-3 psi, maximum gas supply is 100 psig, and accuracy is 2% of span.
