Gas Sensors Overview
Modular sensor design
In order to be able to adapt gas analyses as flexibly as possible to individual measurement tasks, the individual components designed modularly. This resulted in a »modular system« in which the various photometric components such as detectors, emitters, measuring sample cell, etc. can be exchanged. Aluminium with bright gold coating and passivated stainless steel is used as the standard sample cell material. PEEK (polyetheretherketone) is also available for special applications. With this sophisticated sensor design, customer-specific applications can also be realized without the need for a completely new development. The modularity makes replacement and maintenance considerably easier when servicing is required. Completely bonded gas sensors, on the other hand, can only be replaced as a complete unit and thus generate high follow-up costs (total cost of ownership) in case of maintenance. Optionally, the different gas measurement modules can also be equipped with a pressure measurement (P.sens) oxygen measurement (O2.sens) or a humidity measurement (HUMI.sens).
