‘PULSAR’ CLASS GAS FILTER CORRELATION NDIR

TYPICAL GASES: CO, CO2, NO, SO2, N2O, CH4 + MORE Gas Filter Correlation is the best type of NDIR for combustion gas analysis. Instead of a

dual beam sample cell and a separate reference cell, this method uses only a single cell for both sample and reference.

This method reduces problems with cell contamination causing a difference in readings. Also,

with Gas Filter Correlation we fill the filter wheel interfering gases e.g. H2O, CO2 to eliminate the effects of these gases when measuring for example low CO in the presence of percent

levels of these other gases.

The ‘Pulsar’ class also provides superior levels of linearity throughout the 10,000:1 range

ratio.

SERIES 4 TECHNICAL SPECIFICATION - PULSAR MULTIGAS NDIR

o Available in 1, 2, 3, 4, or 5 gas channel configurations

o New design for improved specification

o Supplied with software suite for use over Ethernet or RS232

o Suitable for ultra-low measurement range applications

o Rotating filter design for minimal cross sensitivity

The new Pulsar detector from Signal has been upgraded to provide our best ever performance specification. With the lowest

drift on the market it is ideal for low range applications or high accuracy measurement. The GFC design of the detector

prevents cross sensitivity to other gases and also removes the risk of contamination through a sample containing particulate

matter. It provides a cost effective, low maintenance option for even low concentration measurement applications.

‘QUASAR’ CLASS CHEMILUMINESCENCE DETECTOR

The Signal ‘Quasar’ series of Chemiluminescence NOx analysers is unique in the market with the very special ozone generator and the low level of quenching effects from CO2 and H2O. The “soft discharge” neon lamp ozone generator is unique among competitors with its ability

to use air as its feed gas without any Nitrogen in the air becoming NO and NO2. High voltage corona discharge techniques and UV lamps both suffer from this and major competitors recommend the use of 100% Oxygen to avoid this effect, and this is expensive

compared to air.

The high vacuum and heated design also eliminates quenching and increases signal strength and also avoids any condensation in the sample and measurement which could cause losses

of NO2 in condensate. The vacuum pump is of a dry diaphragm design. We offer a single NOx detector, dual continuous NO, NO2, NOx detectors, non vacuum for

dilute and dry samples (e.g. CVS vehicle testing, off road dry NOx testing), and NOx, NH3, NO2 using selective converters and dual continuous detectors.

‘SOLAR’ CLASS FLAME IONIZATION DETECTOR

The Signal ‘Solar’ Flame Ionization Detector product line is unique in the market with its precision machined, monobloc arrangement of ceramic isolated flame jet tip cylindrical collector and venturi effect air/fuel/sample design.

This has produced reproducibility of production so that every analyser has exactly the same

characteristics.

The need for this uniformity is important when measuring hydrocarbons as there are many different species in the measurement mix and barometric changes can be a problem.

The monobloc design encompasses the hot oven, the heated filter, span/zero/cal valve and the sample pump. Thus, a very compact and leak proof design is provided. The sample

pump uses a brushless DC motor for total reliability. We offer a heated 191°C single FID for total hydrocarbon, a Methane only single FID using a

cutter to remove/convert all hydrocarbons except for Methane, and a dual detector for continuous total hydrocarbons, Methane, and non Methane. ELECTRONIC PROPORTIONAL BAND FLOW CONTROLLERS
