Product Description:

 

The Silarex  is one high-end type of multi-gas measurement sensor which based on the infrared absorption technology and comply with the highest standards in accuracy, reliability and efficiency.

Due the consequent use of this optical principle the systems work without abrasion or chemical reactions and are nearly maintenance free.

 

As basis the IR principle uses the individual absorption spectrum of the gas to be detected and specifies the concentration by the precise quantitative analysis.

Because all measured gases absorb IR radiation in a different spectrum a so called “fingerprint” is given which ensures a selective characterization with less cross sensitivities. 

An integrated evaluation electronic delivers finally an easy to use concentration signal and compensates all temperature- and drift effects.

 

The Silarex housing is made with gold plating housing which can effectively reduce the noise of light source. And the gas Inlet and Outlet are fitted with gas line connectors to allow perfusion of the Silarex.  Tubing with an internal diameter of 3 mm and external diameter of 5 mm is needed to connect up to the measurement cell. Ensure that tubing is securely attached to the inlet and outlet connectors.

 

Meanwhile we have equipped Silarex with heated aluminium Housing to make the stable temperature of sensor, to reduce the fluctuation of measurement date due to the unstable environment temperature. Also with pressure sensor to reduce the gas flow influence. Silarex is the right product for all kind of industry stable gas measurement application.
