INTRODUCTION
1.1 Features
• There are 2 versions of the XTP601 available:
Analyzer with touch screen (capacitive buttons)
Transmitter (base model)
• The XTP601 is calibrated in a specific background gas to match
customer's requirements. This is displayed on the front screen of the
analyzer or via the Application Software.
• The XTP601 provides 2 off 4-20 mA analog output signals that are
proportional to the oxygen concentration. The primary 4-20 mA output
is locked on the calibrated range of the instrument. The secondary
output is user-selectable within the calibrated range.
• Modbus RTU over RS485 protocol serial communications are provided
as standard.
• Accuracy of 1% FS or 0.02% O
2
, whichever is greater. (Zero suppressed
ranges ±0.2% O
2
).
• Zero and span stability of 0.25% of span per month.
• The Thermo-Paramagnetic sensor used in the XTP601 Oxygen Analyzer
has no moving parts. This makes it less sensitive to vibration and
movement and highly resistant to drift over a long period of time,
compared to other sensing technologies.
• Innovative sensor design which minimizes zero drift and offers
increased protection against contamination.
• The robust and weather-proof enclosure (IP66 rated) allows the XTP601
to be installed on-site, at the point of measurement. It is also available
with an explosion-proof casing and certified to II 2 GD Ex d IIB+H2 T6
Gb, Ex tb IIIC T85°C Db IP66 T amb -40°C to +55°C. (Dependant on
O-Ring selection, see Section 1.3.)
• All of the analyzer functions can be accessed via the touch screen
(capacitive) buttons (on display model), 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 XTP601 is certified to ATEX, IECEX, cCSAus, INMETRO & TC TR Ex
for use in hazardous areas.
• 2 x single pole change-over relay alarms for oxygen concentration,
supplied as standard. Can be configured as OFF, LOW or HIGH on the
analyzer (GP1 or EX1) version or LOW or HIGH on the transmitter (GP3
or EX3) version.
