In many applications in process- and analysis engineering, the exact detection of gas concentrations is dispensable. Contrary to other measurement processes, the sensors that are based on the infrared absorption offer important advantages. These sensors deploy the character of the gases, to absorb the infrared radiation at a specific wavelength. Since this is characteristic for the respective kind of gas, the sensor works very selectively and barely shows interference opposite to other gases. In compassion to electrochemical and catalytic sensors, these sensors do not show any seasoning effects.
With the new version of the smartMODULFLOW, the smartGAS (Germany) now offers an OEM-sensor that is based on the IR Radiant source, an interference filter for the wavelength selection and an IR dual detector is housed in an aluminum cuvette for this reason. This cuvette can be integrated into the process and can be flowed through with the respective gas. This buildup provides importing advantages, especially in procedural applications. The aluminum cuvette for example can be held at a constant temperature to exclude temperature dependent effects, As a result from this, a higher measurement accuracy can be achieved. By an additive isolation of the optical components of the gas flow, diverse flow effects can be minimized. Furthermore, the modular and easy to install construction allows a higher flexibility, because the measurement setup of smartGAS is easy to adjust to the customer specific measurement problem, for example by the adaptation of the light path.
The evaluation electronics with the interfaces of the sensor module resides on the board beyond the cuvette. Beneath the standard interfaces (4…20 mA, 0…2,5V) there also is a serial RS485 interface available. The also integrated watchdog, that observes the function of the sensors technology, is of high importance, especially at security relevant applications. The new aluminum version of the smartMODULFLOW is available for the following gases : Acetylene, Butane, Ethane, Ethylene, Carbon dioxide, Carbon monoxide, propane, Methane, R134a and sulfur hexafluoride.
