Gas : XMO2 Thermoparamagnetic Oxygen Transmitter

XMO2 Thermoparamagnetic Oxygen Transmitter Accurate & Reliable Long-Term Measurement
The XMO2 transmitter provides computer-enhanced, drift-free oxygen measurement in a compact, rugged, online transmitter. It can be used wherever accurate and reliable long-term oxygen measurement is critical to process and product quality. This includes inerting/blanketing liquid storage tanks, reactor feed gases, flare gas, catalyst regeneration, oxygen purity and many other applications.


Product Description:

The XMO2 is specifically designed to overcome the limitations of conventional oxygen analyzers. It does not require analyzer shack installation in a general-purpose area, but can be field-mounted at the process measuring point. This minimizes sample conditioning requirements and ensures the best sample and the fastest possible response. Unlike other paramagnetic oxygen sensors, the XMO2 has no moving parts, making it insensitive to mounting position or vibration and providing excellent long-term reliability. The unique, dual-chamber oxygen cell design insures insensitivity to contamination and flow variations and provides a zero and span stability that makes recalibration typically only a biannual requirement.

An on-board microprocessor enables the XMO2 to provide advanced online signal detection and conditioning, real-time error detection and automatic compensation of the oxygen reading for background gas and/or pressure variations. This results in a linearity of better than 0.5 percent of span, a long-term accuracy of 1 percent of span and a stability of 0.8 percent of span per month. A proprietary fast-response software routine enhances the standard response of the thermoparamagnetic oxygen sensor, providing typical times of less than five seconds for a 63 percent response.

The user-friendly XMO2 can be programmed in the field or remotely with application-specific data via an RS232 interface and three-level, menu-driven software. When recalibration becomes necessary, it can be accomplished quickly and easily through software, with no pots to adjust. A complete line of performance-enhancing accessories make the XMO2 even easier to use. These accessories include custom-designed sampling systems and different styles of digital display packages.

The XMO2 transmitter requires 24-VDC power and provides an isolated 4- to 20-mA output signal for oxygen concentration that is programmable for zero and span. It is available in either weatherproof (NEMA 4X, IP65) or explosion-proof (NEMA 7) enclosures and in ranges from 0 to 1 percent to 0 to 100 percent, making it suitable for a wide variety of installations and applications.

Features & Benefits:

  • Measures oxygen from 0.01 to 100 percent in gases
  • No moving parts; maintenance-free
  • Corrosion-resistant design
  • Automatic background-gas compensation
  • Use as stand-alone transmitter or in conjuction with TMO2D or XDP display packages
