WDG INSITU-CENELEC

flue gas oxygen analyzer for atex ii 2 G hazardous area

Direct-sensing insitu probe suitable for applications where the flue gas temperature
does not exceed 1472°F (800°C). Completely field serviceable.
SERIES 2000 CONTROL UNIT

Display: Four-line x 20-character vacuum fluorescent.
Displays combinations of oxygen, time and date, cell temperature, user programmable text, thermocouple mV or cell
mV. Password protection, programmable pressure compensation and context-sensitive help are also provided.
Analog Output: Two isolated linear current outputs. Select
oxygen, cell temperature, thermocouple mV or cell mV. Each
output can be 4-20 mA, 0-20 mA, 20-4 mA or 20-0 mA and
is fully scalable. Hold or track during calibration and select
degree of damping. Maximum load 1200 ohms.
Alarms: Two independent oxygen alarms, each high or low
selectable. One alarm can be allocated to oxygen, calibrate or
verify. Set relays to energize or de-energize on alarm.
Contact Rating: 0.5A, 30V, 10VA max. noninductive load, AC
or DC
Diagnostics: Watchdog timer and service alarms. System test
for A/D, RAM, EEPROM and keypad. Display line 4 reserved
for full text error and diagnostic messages. Twenty entry event
log.

SENSOR

Communications: RS-485 2-way addressable

Principle of Operation: Direct-sensing insitu probe using
zirconium oxide for net oxygen measurement.
