CXT The CXT Explosion Proof transmitter delivers reliable, accurate monitoring
of toxic and combustible gases in potentially explosive and harsh
environments, including hazardous-rated areas. The explosion proof
housing is a rugged design that offers greater protection from being
damaged by impact type incidents. Programmable heaters for both the
sensor and electronics are automatically activated when temperatures
drop below a user selectable level.
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.
Accompanying the LCD display are standard LED alarm indicators that
show when low and high alarm conditions are met. An optional relay
board is available to provide 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.
