Designed to provide thorough, continuous monitoring of many hazardous gases, indoor/outdoor Ultima X Series Gas Monitors offer excellent performance and MSA quality craftsmanship. DuraSource™ Technology offers extended sensor life; HART Protocol provides convenient setup, calibration and diagnostics. Single circuit board increases reliability; MSA patented sensor disconnect-under-power feature allows all sensors to be replaced within hazardous areas without area declassification. Units are built from stainless steel or polycarbonate. Interchangeable smart sensors eliminate the need for re-configuration. Scrolling LCD screen displays sensor reading and gas type; calibration process includes date stamping and ability to calibrate locally or remotely.

The Ultima X Series Sensor X-Change™ Program is a sensor-replacement service that supplies users with calibrated sensor modules when needed, on demand. The program provides easy installation and minimal downtime. Sensors arrive prior to the Ultima X Monitor’s scheduled calibration date. Then, simply change out the old sensor with the new, perform a gas check and the system is operational. Ultima X Series Gas Monitors are well-suited to indoor and outdoor applications in virtually any industry including offshore, refineries, chemical and petrochemical facilities, steel mills, water and wastewater plants, mining, and general industry


Ultima X Series Gas Monitors with X3® Technology

ultima x series with x3 technology

Provide continuous monitoring of combustible and toxic gases and oxygen deficiency. X3 Technology is X to the Power of 3, bringing multi-sensing, signal boost and Modbus output to Ultima X Series Gas Monitors. This technology allows 3 sensors to be connected to a single 1 Ultima X Gas Monitor and provides Modbus RTU output. Each sensor can be remoted up to 3,000 feet from the monitor. Any combination of electrochemical, catalytic and infrared-type sensor is available, a perfect match for all applications and industries.

  • Multi-sensing; up to 31 monitors with up to 3 sensors inputted per monitor for total of 93 sensors.
  • Signal boost: universal 10-256VAC or 7-30 VDC power supply available at remote condulet.
  • RTU output: industry standard RTU format, RS-485 half-duplex communication interface and integration into PLC/DCS systems.

Ultima XE Gas Monitors

ultima xe gas monitors

offer continuous gas monitoring of combustible and toxic gases, as well as for oxygen deficiency. HART Protocol provides increased sensor data, part of costeffective asset management. Calibrate, set up or perform diagnostics with HART from any point along the 4-20 mA line. Advanced features include:

  • DuraSource™ Technology for improved sensor life.
  • FM, UL, CSA, ATEX, and IEC approvals. SIL 2-certified products.
  • Disconnect-under-power, allowing for hazardous area sensor replacement.
  • Interchangeable smart sensors enable easy installation and replacement.
  • Onboard LEDs and relays provide increased alarm and fault condition indication.

Ultima XIR Gas Monitors

ultima xir gas monitors

Provide microprocessor-based, infrared-point gas detection for continuous monitoring of combustible and carbon dioxide gases and vapors. Ultima XIR Monitors employ dual-wavelength heated-optics technology, providing definitive compensation for temperature, humidity and aging effects. IR technology offers excellent longterm stability, eliminating the need for frequent calibrations and reducing overall cost of ownership. Ultima XIR Monitors operate over extended temperature ranges, have rapid response time and are immune to sensor poisoning. Ultima XIR Monitors function in both high gas and low oxygen environments and contain no moving parts, jumpers, switches, or pots.

Ultima XIR Monitors offer the same features as Ultima XE Gas Monitors plus advanced features including:

  • FM, UL, CSA, ATEX, and IEC approvals.
  • DuraSource Technology for improved sensor life.
  • 10-year warranty on IR source.
  • Field-selectable algorithms for many hydrocarbon-based gases.
  • Fail-to-safety operation designed without sintered disk.
  • SIL2-certified products.

Ultima XL/XT Series Gas Monitors

ultima xl xt series gas monitors

Are economical continuous gas monitors. Single-sensor units use catalytic, electrochemical and infrared gas detection technologies for combustible and toxic gases and for oxygen deficiency. HART Field Communications Protocol running over 4-20 mA output provides convenient setup, calibration and diagnostics. Hand-held HART communicator, controller or laptop provides display, while local calibration employs LEDs and pushbuttons. Ultima XL Gas and Ultima XL Infrared Combustible Gas Monitors are explosion-proof with stainless steel enclosures, while the Ultima XT Gas Monitor is housed in general purpose plastic

  • Sensor disconnect-under-power without declassifying hazardous area.
  • Interchangeable smart sensors; no reconfiguration required.
  • 1 circuit board for increased reliability and easier serviceability.
  • Calibrate, set up or perform diagnostics with HART from any point along 4-20 mA line.
  • Easy installation with 2-piece field wiring connectors.
  • Asset management using HART interface.

Wireless Communication System i

msa wireless communication system

is an ideal solution for gas detection needs at locations where no infrastructure exists. Combustible and toxic gases can leak virtually anywhere, and leaks may not occur near a facility’s gas detection instrument installation area.

  • 900 MHz radio that communicates to a gateway provides reliable real-time detection data at distances of up to 1 mile with clear line of sight.
  • Accepts either Analog or Modbus inputs.
  • Power options include solar panel, battery and charger to help ensure up to 2 weeks of autonomous operation.
  • Wireless HART adapter can be added to any MSA HART-enabled field device to communicate with any existing wireless HART network.
