Rosemount™ 628 Universal Gas Sensor

Rosemount 628 Sensors for combustible and toxic gas detection. Intrinsically safe, hot-swappable modules for use with the Rosemount 928 Wireless Gas Monitor.

Rosemount 628 Sensors detect combustible or toxic gases. These intrinsically safe Modules are compatible with the Rosemount 928 Wireless Gas Monitor. Toxic gas sensors incorporate industry-standard technology that is used in conventional wired gas detectors to bring consistent toxic gas sensing to challenging and remote locations. Combustible gas sensors use Micro‑Electro‑Mechanical Systems (MEMS) technology to classify and detect flammable gas, providing accurate results without use of calibration adjustments.
