From Fixed Gas Detectors
The CXT monitors toxic and combustible gases in potentially explosive and harsh environments, including hazardous-rated areas. The rugged explosion proof housing offers protection from being damaged by impact type incidents and is capable of containing, controlling and venting any possible flash or explosion. The large LCD display shows gas concentrations and engineering units as well as historical data for the last 30 minutes. Navigation through the menu is driven by a magnetic keypad and the user can change alarm set points, instrument configurations or enter into maintenance mode for non-intrusive sensor calibration. Programmable heaters for both the sensor and electronics are automatically activated when temperatures drop below a user selectable level. An optional relay board provides three, 5-amp relays that can be used to drive audible/visual alarms, or activate exhaust fans. The CXT’s security menu allows entry of an authorization code to lock critical parameters.
