Features
•
The XTC601 standard analyzer can now be supplied to meet the
requirements of IEC 61508 SIL 2. This will allow the user to integrate
the unit in a functional safety system.
•
The robust and weather-proof enclosure (IP66 rated) allows the XTC601
to be installed on-site, at the point of measurement. The EX version
is housed in an explosion-proof casing, and is certified to II 2GD Ex d
IIB+H2 T6 Gb, Ex tb IIIC T85°C Db IP66 Tamb -40°C to +55°C.
•
The XTC601 provides 2 off 4–20mA analog output signals that are
proportional to the Target Gas concentration. The primary 4–20mA
output is locked on the calibrated range of the instrument. The
secondary output on the standard instrument is user-selectable within
the calibrated range. On the HCG version this output indicates the
selected phase:
1. Phase 1 = 7mA to 9mA
2. Phase 2 = 11mA to 13mA
3. Phase 3 = 15mA to 17mA
•
Modbus RTU over RS485 protocol serial communications are provided
as standard.
•
The XTC601 HCG measurement phase can be changed via the HMI, a
Modbus RTU register or by 4–20mA input signal.
•
Accuracy of 2% of span for standard ranges.
•
Zero and span stability of 0.5% of span per month.
•
The sensor used in the XTC601 Binary Gas Analyzer has no moving
parts. This reduces sensitivity to vibration and movement.
•
All of the analyzer functions can be accessed via the touch screen
(capacitive) buttons or via the Application Software.
•
Low cost of ownership due to minimal maintenance.
•
When required, the casing unscrews to allow for easy access to the
sensor, enabling maintenance to be carried out quickly and easily.
•
The XTC601 is certified to ATEX, IECEX & cQPSus for use in hazardous
areas.
•
2 x single pole change-over relay alarms for Target Gas concentration,
supplied as standard.
