Figure 1 XTC601 Thermal Conductivity Analyzer Versions
The XTC601 Thermal Conductivity Analyzer is based on Michell Instruments’ advanced
proprietary technology. It measures the percentage levels of a Target Gas in a selection
of background gases, including nitrogen, hydrogen, carbon dioxide, methane and
biogas. The sensor is housed in a weather-proof (GP version) or explosion-proof (EX
version) casing - both IP66 & NEMA 4 rated. It is suitable for a range of applications in
safe or hazardous areas.
The XTC601 is available in single phase configuration for measurement of a variety
of binary gases, or in three phase 'HCG' configuration for hydrogen cooled generator
applications only.

XTC601 User’s Manual
297400 Issue 3.1, January 2017
INTRODUCTION
1.1 Features
• There are 2 casing versions of the XTC601 available, all of which can be
configured with 2 port (sealed reference) or 4 port (flowing reference):
Analyzer with display and touch screen (capacitive) buttons
Transmitter
• The XTC601 provides 2 off 4-20 mA analog output signals that are
proportional to the Target Gas concentration. The primary 4-20
mA 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:
4 mA to 8 mA indicates phase 1
10 mA to 14 mA indicates phase 2
16 mA to 20 mA indicates phase 3
3.5 mA indicates no phase
• Modbus RTU over RS485 protocol serial communications are provided
as standard.
• 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 Thermal Conductivity Analyzer has no
moving parts. This reduces sensitivity to vibration and movement.
• 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 T3 Gb, Ex tb IIIC T137°C Db IP66 T amb -40°C to +55°C.
• 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, cCSAus & TC TR Ex for use in
hazardous areas.
• 2 x single pole change-over relay alarms for Target Gas concentration,
supplied as standard.

Michell Instruments 3
INTRODUCTION
1.2 Applications
The XTC601 binary gas analyzer is designed for use in process environments.
A sample system may be required to ensure that a clean, dry gas with no particles
or oil-mist is delivered to the XTC601. This will ensure the sensor is not damaged or
contaminated by the process. Michell Instruments is able to supply a quotation for such
a system.
Examples of applications include:
• H2generator cooling systems (Power Generation)
• H2in heat treatment furnaces (Metals)
• CO2in fermentation process (Food)
• CO2in biogas
• Ethylene Oxide sterilization process (Food)
• H2in blast furnace top gas (Steel)
• H2in hydrocarbons (Petrochemical)
• He recovery (Industrial Gas)
• N2in CO2(Industrial Gas)
1.3 O-Ring Selection
The XTC601 has only one elastomeric seal in the gas path. There are 3 types of O-rings
available to offer greater flexibility with material compatibility. The Viton O-ring is fitted
as standard. The Ekraz O-ring is available for solvent resistance. For extremely low
temperatures there is a closed cell Silicone O-ring.
To comply with Hazardous Area certification, the material used in the EX1 & EX3 versions
is dependent on the lowest ambient temperature of the area the units are to be installed
in:
Ambient operating range:
-40°C to +55°C (-40°F to +131°F) (for Silicone O-ring)
-15°C to +55°C (+5°F to +131°F) (for Viton O-ring) - Standard
-10°C to +55°C (+14°F to +131°F) (for Ekraz O-ring)

OPERATION
2 OPERATION
The XTC601 is not certified for use with ambient oxygen
levels that are enriched (i.e. over 21% O2)
This analyzer has been manufactured within our quality procedures and is configured
according to the purchase order. When it is installed and used as per the manufacturer’s
guidelines, it will operate within the stated specification.
Before starting operation it is recommended that the user becomes familiar with this
manual in which all the equipment controls, indicators, the elements of the display and
the overall menu structure are described.
2.1 Preparation
Before applying power and beginning the flow of gas,
please ensure that the system has been properly installed
following the instructions in Section 4.
Check that the wiring has been completed correctly.
Zero and Span gas cylinders with correct regulation and flow control should be in place
before installing and powering up the analyzer. Commissioning should include a check
with both gases and, if necessary, a field calibration performed.
All analyzers will be calibrated with an inlet pressure of 1 barg (14 psig) with an
atmospheric vent and flow rate of 300 ml/min (0.63 scfh). The calibration gas applied
to the analyzer should be at the same pressure and flow rate as the process gas being
sampled.
• Sample Inlet Pressure: 0 to 3 barg (0 to 43 psig) with atmospheric vent
• Sample Flow Rate: 100 to 600 ml/min (0.2 to 1.27 scfh)

OPERATION
2.2 Powering up the Analyzer
After all the preparation work has been done and the
installation and wiring have been checked, turn on the
analyzer and wait for at least 30 minutes (or until Cell
T Not Stable message disappears). This will allow the
analyzer to reach its operating temperature of +50°C
(122°F) and protect it from any condensation forming in
the sensor.
There is no power switch on the XTC601 Thermal Conductivity Analyzer. It is turned on
automatically once a 24 V DC power source is applied. After the analyzer is powered
up, the display will be illuminated. The analyzer takes up to 5 seconds to initialize, and
during this period will display the product type and firmware version number.
