are displayed continuously on a easy-to-read, 0.4 (10.2 mm) high, 4-1/2
digit liquid crystal display (LCD). The instrument can be purchased in a
variety of mechanical configurations ranging from a general purpose,
portable device, to a NEMA 7 (explosion proof) system. The electronics
enclosure used for the portable and panel mounted versions is made from
durable polycarbonate and, together with the gasketed seals, is rated watertight
NEMA 4X (IP66). The gas inlet and outlet connections on the sensor
housing are quick-connect types. One-quarter inch stainless steel
compression fittings are available upon request.
OXYGEN SENSOR WITH EES
Series 2000 Percent Oxygen Analyzer features a patented, extended life
oxygen sensor with EES (enhanced electrolyte system). This sensor
provides exceptional performance, accuracy, and stability. For
applications where carbon dioxide is present in the sample gas, the EES
retards passivation of the sensor anode by allowing the products of
oxidation to dissolve in the electrolyte. In effect, the sensor is renewed
continuously, resulting in an increase in sensor life even if exposed to
limited amounts of carbon dioxide. In addition, the enhanced mechanical
design of the sensor ensures longer life, and virtually eliminates leakage
of electrolyte, a nagging (and expensive) problem associated with sensors
that require electrolyte maintenance.
eloquence of the Series 2000 Percent Oxygen Analyzer is its ease of use.
The front panel contains five switches that provide access to the
instruments settings. Each analyzer is equipped with three oxygen alarm
relays and one status alarm relay as standard equipment. All four relays
are Form C (SPDT) types rated at 10 amps at 115/230 VAC and 30 VDC. Each
relay is user configurable for fail-safe operation. In addition to the
alarm relays, the analyzer is equipped with a built-in audible alarm,
as well as three front panel LEDs for visual indication of an alarm
Series 2000 Percent Oxygen Analyzer comes equipped with two analog
outputs, 4-20 mADC and 0-2 VCD, for use with recorders, dataloggers, etc.
For enhanced communications, the Series 2000 Percent Oxygen Analyzer can
be configured with optional RS-232C or RS-485 serial communications. For
multiple point installations, the RS-485 format is capable of sending
digital signals over greater distances, and controlling each monitor using
the same communication channel.
