New version of IR gas sensors in aluminum cuvette
with improved performance
In many applications in process- and analysis engineering, the exact
detection of gas concentrations is indispensable. 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
Mikrosensorik GmbH now offers an OEM-sensor that is based on the IR
absorption and that can be integrated in a process easily. The sensor
element that consists of a powerful 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 important 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 minimised. 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…2,5 V) 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.
Versions for other gases are available on request.
smartGAS GmbH
The company smartGAS Mikrosensorik GmbH develops, produces and
sells innovative gas sensors that are based on the infrared technology
(IR). These IR gas sensors allow to measure gases selectively und to
affect their concentration precisely. The spectrum of the measurable
gases is expanded constantly. The sensors are offered as customer
specific OEM-modules and are applied in the areas safety engineering,
refrigeration- and climate engineering, high voltage engineering,
analysis equipment and process engineering.
