The FTC320 is the new generation of our thermal conductivity analyzers. With the new electronics the measuring accuracy could be further improved.
The new electronics and software allow the solution of up to 99 tasks with one instrument and an extension for selective oxygen (O2) measurement by the additional module.
The EX version is certified for zone Ex II 3G Ex nR IIC T4 Gc.
The device has a comfortable operating menu which allows easy adjustment, parameterization and configuration. In addition, operating and data access is possible via an RS232 interface. Various analog signal inputs and outputs are also available.
The robust design of the FTC320 is designed in protection class IP65. It can be operated at ambient temperatures from -20°C to +50°C and is pressure resistant up to 20 bar.
For the measurement of hydrogen in nitrogen the smallest measuring range is 0 to 0.3 vol.%.
The FTC320 Thermal Conductivity Analyzer can be set up to allow switching between different measurement tasks.
The FTC320 features a highly effective cross-sensitivity compensation routine that can be flexibly adapted to the respective measuring task. It requires an external voltage signal as an input variable that reflects the concentration of the gas components causing the cross-sensitivity.
The drift is specified with 1% of the reference.
The noise could be improved from 50ppm (FTC300) to 5 ppm (FTC320).
The temperature dependence of 5 ppm per 1°C is also significantly lower than the FTC300’s 50 ppm.

The additional module for oxygen measurement extends the application range of the FTC320 for non-binary gases with oxygen content. The additional module for oxygen measurement extends the application range of the FTC320 for non-binary gases with oxygen content.
The oxygen measurement is based on an electrochemical cell, which is lead-free, RoHS compliant with a long lifetime and fully CO2 resistant.
The electrochemical cell is sensitive to oxygen partial pressure. The output signal of the oxygen sensor is digital and is processed in the FTC320.
To provide a pressure-independent output signal in Vol.%, the signal is compensated by the internal pressure sensor.
The display of the oxygen concentration on the display as well as the calibration, the setting of the measuring ranges and the alarm relays are provided.
The overall setup is shown in figure 1. Figure 2 shows the installation of the electrochemical module. It is attached to the output of the FTC320 with a 6 mm compression fitting (1). A tube (2) leads the gas to the rectangular stainless steel adapter (3). The electrochemical cell (4) is screwed into the adapter (3). A cap (5) is placed on the cell (4). A connector inside the cap is used to connect the cell to the FTC via the cable (6).
