Difference between gas sensor and gas analyser

Are fast­Li­ne gas sen­sors „gas sen­sors“ or „gas ana­ly­zers“? The dif­fe­rence bet­ween a gas sen­sor and a gas ana­ly­ser is beco­ming incre­asing­ly blur­red. Ori­gi­nal­ly, 20 years ago, NDIR gas sen­sors only pro­vi­ded an infrared absorp­ti­on signal. In order to dis­play the con­cen­tra­ti­on of the gas, exter­nal soft­ware had to cal­cu­la­te this signal with mea­su­re­ment signals…

New Measurement Platform V3

New plat­form V3 „fast­Li­ne“ for gas sen­sors released The new plat­form V3 fea­turing the opti­cal infrared gas mea­su­re­ment tech­ni­que is released after inten­si­ve test­ing for dual-chan­­­nel, dual-beam con­fi­gu­ra­ti­on. The plat­form can be easi­ly adapt­ed for dif­fe­rent gases with dif­fe­rent con­cen­tra­ti­ons to be mea­su­red. Two or more gases can be mea­su­red in two mea­su­ring chan­nels. Extrem…

Principle of dual-beam NDIR gas sensor

NDIR Technology fastLine sensors

Mea­su­re­ment prin­ci­ple NDIR stands for None-Dif­frac­­­ti­­­ve Infrared and is a pho­to­me­tric, non-inva­­­si­­­ve method of mea­su­ring gas con­cen­tra­ti­ons. NDIR tech­no­lo­gy mea­su­res the absorp­ti­on of infrared (IR) light by a gas in a spe­ci­fic opti­cal spec­trum. It make use of the phy­si­cal pro­per­ty of spec­tral absorp­ti­on of the gas: Each gas only absorbs light in cer­tain spectral…
