Allgemeines

Das CLD 500 basiert auf dem gleichen Messprinzip wie konventionelle CLD‘s ist aber 1.000 mal schneller durch eine optimierte Messzelle und kürzeste Gaslaufzeiten. Die patentierte Messtechnik erlaubt die Messung von NO und NO2 im Rohgas auch bei hohen Temperaturen und variierenden Abgasgegendrücken direkt im Zylinder oder hinter dem Auslassventil.

Funktionsschema

A chemi-luminescence detector (CLD) is the industry standard method of measuring nitric oxide (NO) concentration.

The reaction between NO and O3 (ozone) emits light. This reaction is the basis for the CLD in which the photons produced are detected by a photo multiplier tube (PMT). The CLD output voltage is proportional to NO concentration.

The light-producing reaction is very rapid so careful sample handling is important in a very rapid response instrument. The Cambustion Fast CLD uses a unique sampling system coupled with miniaturised CLD technology to give millisecond response times.

The Cambustion Fast CLD has two remote sampling heads controlled by a Main Control Unit and is capable of simultaneous sampling in two locations.
