Also for complex gas mixtures

 

The ULTRAMAT 6E measures up to four and the ULTRAMAT 6F up to two infrared-active components in a single device. Using optical couplers and the optional use of optical filters to increase selectivity means that the measurement of complex gas mixtures is also possible in many cases. This ensures measurements of low concentrations as well as low detection limits.

 

Appropriate materials in the gas channel allow the analytical devices to be used even for measurements of gas mixtures with corrosive components or corrosive measuring components. Gas-tight separation of electronics and physical components when using the field device design with class IP65 protection and a purging gas connection guarantees a long service life even under harsh ambient conditions. The field device design is also the basic variant for the optional heating of the analysis unit for measuring high-boiling components and for use in hazardous zones.

Increasing Selectivity

Up to two infrared-active components and oxygen can be measured in one device. The use of optical couplers and optical filters in the IR physics leads to an increase in selectivity and in many cases also enables the measurement in complex gas mixtures. This ensures measurements of low concentrations as well as low detection limits. The OXYMAT physics is based on measuring oxygen using the paramagnetic alternating pressure method. This ensures absolute linearity and allows parameterization of smallest measuring ranges from 0 to 0.5% (detection limit 50 ppm) up to 0 to 100% in one device.

Even for the smallest measuring ranges

The SIL 2 classification obtained by OXYMAT 6 makes it easier for plant operators to comply with the often required proof of risk reduction. The OXYMAT 6 measures oxygen using the paramagnetic alternating pressure method. This guarantees perfect linearity and enables parameterization of smallest measuring ranges from 0 to 0.5% (detection limit 50 ppm) up to 0 to 100%, and even 99.5 to 100% in a single device. High-quality materials in the gas channel even enable the analytical devices to be used for measurements of corrosive gas mixtures. The detector unit has no contact with the measuring gas, thus allowing it to be used under harsh conditions while guaranteeing a long service life at the same time.

 

Long lifetime

Gas-tight separation of the electronic and physical components when using the field analyzer design with class IP65 protection and a purging gas connection guarantees a long lifetime even under harsh ambient conditions.

Experts in trace oxygen

The OXYMAT 64 can measure oxygen concentrations in the smallest traces, even down to the minimal measuring range of 0...10 ppm. This is most relevant in air separation plants, in the technical gas production, and welding of high-alloy steels, titanium, and the like under a protective atmosphere. Further applications are realized in hardening shops, in the chemical industry, and in the food industry.

High linearity

The OXYMAT 64 operates with ZrO2 sensors. The sample gas flows through a tubular sensor which is heated to 650°C at a constant flow rate. The outside of the sensor is exposed to ambient air acting as a reference electrode. Due to the concentration differences on both sides, there is partial pressure that differs. Since ZrO2 is electrically conductive at 650 °C, an ion migration occurs towards of the lower partial pressure. This results in a potential difference between the two electrodes, which is a measure of the oxygen concentration in the sample gas. 

 

Application-specific sensors

Depending on the application, a catalytically inactive ZrO2 sensor and a catalytically active ZrO2 sensor are available. The two sensors differ in the electrode material and react differently to flammable accompanying components. 

Both variants are characterized in particular by their high linearity and also offer all the advantages of the Series 6, such as the intuitive operating concept and the open interface architecture.

Specializing in hydrogen and noble gases

For continuous measurement of hydrogen and noble gases, the specific thermal conductivity of the sample gas mixture is measured and used to calculate the concentration. Only binary gas mixtures can be measured directly. If more than two components are present, the concentrations of all other components must be measured separately using other measuring methods. The CALOMAT 6 can carry out internal interference correction after transmission of the external measurement results. There is no need for an external computer.

Highly dynamic measuring range

The CALOMAT 6 features a highly dynamic measurement range (e.g., 0–1% and 0–100% H2, parameterizable) and low T90 time. It is a high-end analytical device available in a 19" inch design or in a robust field housing for installation in a harsh environment. With its additional monitoring unit, the CALOMAT 6 with field housing is suitable for installation in hazardous areas 1 or 2. In general, its applications cover all areas, from measurement of gas purity to use in processes for managing production processes and ensuring product quality.

The analyzers can be integrated easily into the automated network with RS 485, PROFIBUS DP, and PROFIBUS PA interfaces. They can also be parameterized and operated using the PDM tool. For fast and easy maintenance, the analytical devices can also communicate with the SIPROM GA software tool that is integrated into the Ethernet using TCP/IP.

Measures hydrogen and noble gases in corrosive gases

The CALOMAT 62 is a thermal conductivity analytical device specially designed for applications in corrosive gases. Concentration of gas components such as Cl2, HCl, and NH3 can be measured directly, along with H2 and N2 in aggressive environments. This results in a number of possible applications such as in chlor-alkali electrolysis, steel production and processing, LNG facilities, ammonia synthesis, fertilizer production, and in the petrochemical industry.

With integrated interference gas correction

The measuring principle of the CALOMAT 62 is based on the measurement of thermal conductivity, a physical quantity that is different for each gas. The signal is determined by a measuring bridge which consists of two electrical resistances in the sample gas channel and two resistances in the reference cell. Depending on the application, there is a choice between an enclosed gas cell and a flushed reference gas cell.  Like the CALOMAT 6, the CALOMAT 62 also features the internal and external correction of influences caused by cross gases.  The CALOMAT 62 is available both in a compact 19" housing and in an IP65 field housing with the possibility of purging. Gas-tight separation of the electronics and analyzer part is available.

Specializing in hydrocarbons

Gas analyzers with an FID (flame ionization detector) are well suited for continuous total hydrocarbon measurement. The measurement is not component specific but substance-class specific. In the first approximation, the measurement result is proportional to the number of C atoms in the respective molecule.

All-round use

The variants of the FIDAMAT feature a wide range of applications. Almost every application can be executed, from trace hydrocarbon monitoring in high purity gases, which is made possible by high resolution and small differences in response factors, to total measurements of hydrocarbons in the presence of corrosive gases. A requirement for the latter application is the use of a filter that is wear-free and corrosion-resistant and the use of a quartz capillary as the measuring gas capillary. The high, adjustable operating temperature for the sample gas channel and detector also facilitates the measurement of high-boiling mixtures and the measurement of hydrocarbons at water vapor concentrations of up to 100%.

 

Committed to safety

Special attention was paid to safety functions. After automatic start at the end of the warm-up phase and automatic measurement operation, a controlled self-monitoring function takes place. If the detector flame goes out accidentally, it is automatically re-ignited. In the event of non-ignition, an alarm is triggered and the gas supply is automatically switched off by a solenoid valve. The purging function in the event of a device failure, prevents the accumulation of toxic, corrosive, or explosive substances inside the device. In addition to transmitting the fault message via binary output contacts, all status messages can be called up individually on the display or through the serial interface.
