ULTIMA® X Gas Monitors[ Providing a unique Range of Capabilities]

The ULTIMA X series of gas moni-tors is available with catalytic sen-sors for combustible gas and elec-trochemical sensors for toxic andoxygen [ULTIMA XE] or infrared forcombustible gas [ULTIMA XIR].

The state-of-the-art design provi-des ease of use and maintenanceand notably the XIR technology’soutstanding long term accuracyextends the calibration interval.

All ULTIMA X series monitors areprotected by a rugged, explosionproof stainless steel enclosure andare suitable for indoor and out-door applications in virtually anyindustry including offshore opera-tions.

ULTIMA X are state-of-the-art gas monitors for continuousdetection and monitoring of combustible gases, toxics andoxygen concentration.

The monitors can be deployed asstand-alone units, but also providea 4 to 20 mA output for connec-tion to controllers. In addition, theULTIMA X3 range now supportsModBUS RTU communication withPLC, DCS or other control systems.

ULTIMA® X [ Highlights]

■ Sensor Change under PowerMSA’s patented sensor designallows for quick and easy sensorchanges in the field, even in hazardous areas.[catalytic and electrochemicalsensors]

■ Interchangeable Smart SensorsPre-calibrated sensor modules areready for installation out of thebox. No tools are needed to mountthem in the field. Sensor changesare recognised, signalled on thedisplay and indicated by the LEDs.[catalytic and electrochemical sensors]

■ Versatile DisplayThe liquid crystal display alternatesbetween gas concentration andgas type, and features scrolling textdiagnostic indications.

■ Unified Hardware DesignA single device with three sensingoptions: catalytic, electrochemicaland infrared absorption.The ULTIMA X series with unifiedsingle board electronics marks the state-of-the-art in monitoringcombustible and toxic gases andoxygen.

■ Onboard LEDs and RelaysOptional “quick check” LEDs at the display unit provide systemcondition indications at a glance,even from a distance. Four optionalfield-programmable relays providethree levels of alarm and fault output.

��� ULTIMA X3

In addition to all thebenefits of the ULTIMA Xseries, X3 gas monitorshave digital communi -cation capabilitiesand feature up to threesensors at the same time at a single device.

Allowing for variable sensor place-ment, ULTIMA X series gas moni-tors have multiple enclosure entries for left, right or bottomwiring. The monitors are also suitable for remote sensing applications, with up to 15 m between sensor and electronics.

The modular design allows forpre-installation and wiring of themain enclosure at early stages ofsite construction. Main electronicsand calibrated sensors can beeasily added at commissioning toreduce risk of loss or damage andmaximise sensor life.

ULTIMA X catalytic and toxic“Smart Sensor” modules store allcalibration data internally, allow-ing convenient sensor presettingand calibration in the workshop.Calibration in the field is also possible, e.g. if required by regula-tions. No tools are needed for connecting or disconnecting sensormodules, and power to the moni-tor can remain on.

IR source Analytical detector

Referencedetector

Beam splitter

Combustible gas cloudSapphire window

Mirror

An electronically modulated source of infrared energy and twodetectors convert the infraredenergy into electrical signals. Eachdetector is sensitive to a differentrange of wavelengths in the infra-red spectrum. The source emis-sion is directed through a windowin the main enclosure into anopen volume. A mirror, protectedby a second window, directs theenergy back into the main enclo-

sure and onto the detectors. Thepresence of a combustible gas inthe open volume will reduce theintensity of the source emissionreaching the detector, but not theintensity of the source emissionreaching the reference detector.The microprocessor monitors theratio of these two signals and cor-relates this to a % LEL combusti-ble reading.

[ ModBUS Network Example]

ULTIMA® X3 Technology[ Digital Data Transfer and up to

3 Sensors per Monitor]

The ULTIMA X3 has all thebenefits of the ULTIMA X seriesand is also capable of digital communication. A maximum of 31 ULTIMA X3 transmitters can beconnected to the same line viaModBUS RTU. Since ULTIMA X3

units can be equipped with up to3 sensors each, 93 sensors in allcan share a single signal line.The wiring effort is minimal.
