 Product Description:
MSA Ultima XA fixed gas detectors
Catalytic combustion, electrochemical and infrared gas detection technology
MSA Ultima X Series Gas Transmitter is a microprocessor-based transmitter, designed for customer needs. Latest mechanical and electronic technology for a variety of gas detection requirements-the-art design. The gas transmitter series UltimaX optional stainless steel and polycarbonate shell, continuous monitoring of harmful gases. Advanced sensor technology can be monitored gas, toxic gas and oxygen dangerous.
Features and advantages:
· Ultima XA waterproof, anti-corrosion plastic shell, for the ordinary type;
· MSA company unique patented technology in the field uninterruptible power supply, without opening the cover, replace the probe without any tools;
· Replacement of the probe on the new probe parameter setting, and put on the probe, the detector can be automatically recognized and accept the new type of probe and alarm parameters;
· Detectors, you can display the name of the gas concentration value and the type of gas, and can display a variety of messages;
Design highly integrated, modular wiring port and signal processing are all focused on a single circuit board, can significantly reduce the incidence of failure in the installation and use;
• You can choose to configure the built-in relay output, including three gas concentration alarm and a fault alarm. Can select the built-in LED status indicators, the gas concentration alarm or detector fault alarm more intuitive and obvious;
· Stainless steel shell, porous interface, optional mounting orientation;
· Detect some gas gas, you can use the controller in the original range, the new detection range of the probe set;
· Different types of gas detection probe can be used interchangeably;
· HART output optional.
