Features - Michell Instruments XTP601 Series User Manual

INTRODUCTION
1.1

Features

• The XTP601 can be supplied meeting the requirements of IEC 61508
SIL2, allowing the user to integrate the analyzer into their functional
safety system.
• There are 2 versions of the XTP601 available:
General Purpose Analyzer with touch screen (capacitive buttons)
Hazardous Area version of above with flame arrestors
• 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% of reading or 0.02% O
suppressed ranges ±0.2% O
• Zero and span stability of 0.25% of span per month.
• The innovative Thermo-Paramagnetic sensor design 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, and it 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.
• Low cost of ownership due to minimal maintenance. For installation
and commissioning, the casing unscrews to allow for easy access to the
electrical connections.
• The XTP601 is certified to ATEX, IECEX, cQPSus, 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.
