Nemoto Environmental Technology Srl (Italy) launches the IRIS series at SENSOR 2008 stand 7-346.
Incorporating innovative patent-pending optics, the new IR sensor
series fromN.E.T. comprises a standard sensor, IRIS-7P, including optics
and intrinsically safe (IS) circuitry with a 7 pin output, and IRIS-PRO,
an intelligent sensor containing all the necessary integrated
electronics, IS interface and software to provide user friendly outputs,
including a pellistor equivalent output.
Designed especially for the fixed apparatus, the standard 32 mm
size (typical 7-series) with a patent cavity allows tomeet the 60079-29-
1 Standard in terms of performance. The IRIS-PRO hardware has been
developed to comply with SIL specifications and SIL 3 for the software.
Both the sensors IRIS-7P and IRIS-PRO are available for
hydrocarbons, including methane, in % LEL and % vol and for CO2
with detection level in ppm, low % vol and high % vol. They have
been designed and certified to be used in potentially explosive
atmospheres classified as zone 1, 2, 21 and 22 together with an
appropriately certified interface/enclosure.
