SAGITTARIUS (FID) FOR LOWER EXPLOSURE LIMIT MONITORING OF FLAMMABLE GASES Fast response time (T90 in less than 2 seconds). High reliability and stability in time. Ex Proof and EN 1539 certifications. Low management costs. Single/multipoint monitoring, heating up to 200°C. Wall or rack mounting and outdoor ins

WORKING PRINCIPLE F.I.D., flame ionization detector. Through the combustion between clean air, hydrogen and the sample gas, the FID can detect hydrocarbon’s ions that induce a current. This current is directly proportional to the organic chemical concentration inside the sample gas. The FID is considered the most precise and reliable detector on the market, fits any kind of application even for high temperature samples.

The sample taken by the probe is quickly sent to the analysis chamber containing the membrane valves (low maintenance). Various cross-checks of flow rates and pressures guarantee the reliability of the measurement.

SAMPLING LOOP ANALYSIS TECHNOLOGY Our FID analyser is equipped with the best sampling technique. A known volume of sample is repeatedly aspirated, drawn (through a loop), and pushed into the detector, resulting in much more stable, accurate and repeatable results than all standard continuous sample flow technologies. The small volume used keeps analyser clean and reduces maintenance/calibration frequencies.

PC EMBEDDED TECHNOLOGY We integrated a robust industrial PC, that works on Windows® embedded operative system, advantages:  Software supervision on all parameter  High software stability, externally monitored by a watchdog system  Software supervision on every operation step  Analysis trend and alarms/faults storage in the local memory  Simple and clear user interface  USB , Ethernet, Modbus and 4-20

LEL MONITORING SYSTEMS COMPARISON Traditional Flame detector  Frequent calibration and maintenance  Reduced calibration and maintenance costs due to huge Span and zero drifts costs due to our loop sampling system  Unstable readings with interfering  Enhanced reading even with interfering compounds like water or with low compounds like water or with low Oxygen content in the sample oxygen content in the sample.  Low accuracy in readings (±3% LEL)  High accuracy in readings (±0,5% LEL)  Complies with EN 60079-29-1 and EN  Only complies with EN 60079-29-1 1539 (oven and

REQUIREMENTS Our FID systems requires hydrogen and compressed air Hydrogen 4,5 grade pure (3 bar) Air from your network (5 bar) 40 Liters gas cylinder or optional H2 generator Nira filtering system

CALIBRATION AND MAINTENANCE We worked hard to minimize maintenance and calibration frequencies, obtaining record results. Every 6 months: Calibration check, the procedure is guided from the software and takes just few minutes using a preinstalled standard gas cylinder. Once a year, ask for a service visit from our staff.

COMPETENCE IN AFTERSALES Our service department work worldwide every day, on 6 different kind of Nira instruments:  E-mail, remote and phone service.  More than 500 interventions performed per year.  More than 1000 instruments serviced worldwide.  Less than 5 working days to organize an intervention within Europe, 10 world
