ULTIMA XIR/ULTIMA XI/ULTIMA X3

The ULTIMA XI/ULTIMA XIR operation is based on dual wavelength – heated optics technology, providing definitive compensation for temperature, humidity and ageing effects. The IR technology offers excellent long-term stability, eliminates the need for frequent calibrations and reduces overall cost of ownership

ULTIMA XI

The ULTIMA XI Gas Monitor is a microprocessor-based, infrared point gas detector for continuous monitoring of combustible gases and vapours. The optional explosion-proof [NPT] or increased safety [metric] enclosure provide a terminal strip for easy wiring of power and signal.

[Features & Benefits]

latest IR technology from high-tech ULTIMA X series

• intelligent calibration cap, no hand-held controller needed
• simplest one-man calibration on the market
• 4–20 mA output
• “Fail to Safety” operation
• 316 St St enclosure for harshest environments
• operates over extended temperature ranges
• immune to poisoning
• operates in high-gas and low-oxygen environments

ULTIMA XIR

The state-of-the-art design provides ease of use and maintenance and notably the XIR technology’s outstanding long term accuracy extends the calibration interval.
The liquid crystal display alternates between gas concentration and gas type, and features scrolling text diagnostic indications. Optional “quick check” LEDs at the display unit provide system condition indications at a glance, even from a distance. Four optional field-programmable relays provide three levels of alarm and fault output.All calibrations and adjustments made using non-invasive calibrator or controller

All ULTIMA X series monitors are protected by a rugged, explosion proof stainless steel enclosure and are suitable for indoor and outdoor applications in virtually any industry including offshore operations.
The monitors can be deployed as stand-alone units, but also provide a 4 to 20 mA output for connection to controllers.

[Features and Benefits]

• Stainless steel explosion-proof, multiple-entry enclosure
• Large LCD for numerical data as well as clear text messages
• Unified sensor electronics for multiple detection and monitoring technologies
• Single-board design greatly simplifies servicing
• “Quick-check” LEDs indicate system conditions,with good visibility even from a distance
• Optional field-programmable relays
• Remote sensor option
• Automatic compensation for changes in temperature and humidity
• All calibrations and adjustments made using non-invasive calibrator or controller

ULTIMA X3 Technology

The ULTIMA X3 has all the benefits of the ULTIMA X series and is also capable of digital communication. A maximum of 31 ULTIMA X3 transmitters can be connected to the same line via ModBUS RTU. Since ULTIMA X3 units can be equipped with  up to 3 sensors each, 93 sensors in all can share a single signal line. The wiring effort is minimal.

[Multi-Sensing System]

Various combinations of electrochemical, catalytic and infrared sensors available

• Remote diagnostics feasible thanks to sensor condition transmissions
• Gas monitor’s “scrolling display” shows all its sensor types
• ULTIMA X3 monitor operates as slave device on the network
• Optional remote sensor installation allows for a maximum distance of 15 m for each sensor
• Internal relays can be configured for 3 different common alarms or one individual alarm for each sensor
