MSA PRIMAX IR Mode D'emploi page 3

INTRODUCTION
The PrimaX IR Gas Monitor - referred to hereafter as device - is a fixed infrared
combustible gas detector. It is suitable for outdoor and indoor applications
(e.g. offshore industry, chemical and petrochemical industry and water and sewage
industry).
The device utilizes infrared technology to monitor, detect and alert users to
potentially dangerous levels of combustible hydrocarbon gas. Dual source
technology offers 100% redundancy on the optical source to maximize reliability
and lifetime. This device allows for extremely fast response time while providing an
extremely stable output signal.
The device is a stand-alone unit with a 4 to 20 mA output with HART [Highway
Addressable Remote Transducer] digital information encoded on the analog output.
The signal of the transmitter can be used in combination with MSA control units for
further actions in safety or non-safety applications. Contact your MSA
representative for available controllers.
The device is shipped factory-calibrated and is labeled with target gas, calibration
gas and span setting information for ease of use. Any user changes to the factory-
assigned values should be noted on the device labels.
The device is explosion-proof and suitable for installation in hazardous locations.
This sensor is intended for integration with a control system that can alert
operations personnel to the presence of hydrocarbon combustible gas.
The PrimaX IR has been performance tested using methane or propane only,
therefore the instrument is intended for sensing methane or propane specifically or
intended to be used as a general purpose combustible gas detector when
calibrated using methane or propane.
