Permanent Gas Detection Ultima® XL/XT Series Gas Monitors

Ultima XL/XT Series Gas Monitors are economical continuous gas monitors. Single-sensor units use cataytilc ectrochemical, and infrared gas detection technologies for combustible and toxic gases and for oxygen deficiency. HART Field munications Protocol running over 4-20mA output provides convenient setup, calibration, and diagnostics

The hand-held HART communicator, controller or laptop provides a display, while local calibration employs LEDs and push-buttons. The Ultima XL Gas Monitor and Ultima XL Infrared Combustible Gas Monitor are explosion-proof with a stainless steel

  • Enclosure, while the Ultima XT Gas Monitor is in a general purpose plastic housing.
  • Sensor disconnect-under-power without declassifying a hazardous area
  • Interchangeable smart sensors; no reconfiguration required
  • One circuit board for increased reliability and easier serviceability
  • Calibrate, set up or perform diagnostics with HART from any point along the 4-20mAline
  • Easy installation with two-piece field wiring connectors
  • Asset management using HART interface
  • Adjustable full-scale range

Ultima® XE Gas Monitor

The Ultima XE Gas Monitor offers the latest in mechanical and electrical technologies for the continuous gas monitoring of combustible and toxic gases, as well as oxygen deficiency. HART Field Communications Protocol provides increased sensor data, part of cost-effective asset management. HART also provides convenient setup, calibration, and diagnostics. Calibrate, set up or perform diagnostics with HART from any point along the 4-20mA line. HART allows for existing component install and wiring to be used, reducing installation costs. Advanced features of the Ultima XE Monitor include:

  • DuraSource technology offers improved sensor life.
  • FM,UL,CSA,ATEXandIECapprovals.
  • World-class design features one electronics board for maximum reliability and serviceability. The 316 stainless steel, multiple-entry mounting enclosure enables problem free installation and servicing.
  • Disconnect under power, allowing for replacement of sensors in hazardous areas.
  • Interchangeable smart sensors, making installation and replacement extremely easy. New sensors are recognized, triggering automatic alarm and relay setting reconfiguration.
  • State-of-the-art display conveniently alternates between sensor reading and gas type, and features scrolling diagnostic messaging.
  • Onboard LEDs and relays provide increased indication of alarm and fault conditions.
  • SIL-2 Certified

Ultima® XIR Infrared Gas Monitor

The Ultima XIR Gas Monitor provides a microprocessor-based, infrared-point gas detector for continuous monitoring of combustible and carbon dioxide gases and vapors. The Ultima XIR Monitor utilizes al-wavelength heated-optics echnology, providing definitive mpensation for temperature, humidity and aging effects. The IR technology offers excellent long-term stability, eliminates the need for frequent calibrations and reduces the overall cost of ownership. The Ultima XIR Monitor offers the same features as the Ultima XE Gas Monitor plus advanced features including:

  • FM, UL, CSA, ATEX and IEC approvals.
  • DuraSource technology offers improved sensor life.
  • Field-selectable algorithms for a variety of hydrocarbonbased gases.
  • "Fail to safety" operation - designed without a sintered disk
  • SIL-2 Certified

The Ultima XIR Monitor eliminates the need for gas calibration-a simple zero adjustment provides reliable accuracy. It operates over extended temperature ranges, has a rapid response time and is immune to sensor poisoning. The Ultima XIR Monitor functions in both high-gas and low-oxygen environments and contains no moving parts, jumpers, switches or pots.
