not detect the presence of acetylene gas and the presence of
acetylene gas will degrade sensor performance. Custom-built
acetylene sensors are available through your MSA representative.
8. Gas detectors depend on an unimpeded gas flow for proper
operation. In environments where contamination is possible,
ensure that the flow remains unobstructed at the sensor. Failure to
follow this may prevent gas detection and generate inaccurate
readings.
9. CSA performance Certification to standard C22.2 No. 152 is valid
only when the instrument is calibrated on methane per the
instruction manual.
10. Install Product in accordance with all markings and the regulations
of the country in use.
11. Product components may have different hazardous location
ratings. Ensure all components are suitable for the area of
installation and protection technique.
Failure to follow the above can result in serious personal injury or loss of life.
1. As with all gas monitors of these types, high levels of, or long
exposure to, certain compounds in the tested atmosphere could
contaminate the sensors. In atmospheres where an Ultima X
Series Gas Monitor may be exposed to such materials, calibration
must be performed frequently to ensure that operation is
dependable and display indications are accurate.
2. The Ultima X Series Gas Monitor must not be painted. If painting is
done in an area where a Monitor is located, care must be
exercised to ensure that paint is not deposited on the sintered,
metal flashback arrestor in the inlet fitting of the Ultima X Series
Gas Monitor, if so equipped. Such paint deposits would interfere
with the diffusion process, whereby a sample of the atmosphere
being monitored diffuses into the Monitor.
3. The only absolute method to ensure proper overall operation of an
Ultima X Series Monitor is to check it with a known concentration
of the gas for which it has been calibrated. Consequently,
calibration checks must be included as part of the routine
inspection of the system.
4. Protect the Ultima X Series Gas Monitor from extreme vibration.
Do not mount the sensing head in direct sunlight as this may cause
overheating of the sensor.
Failure to follow the above can result in injury, product damage and/or an unsafe
condition.
