Description

The CXT2 Explosion Proof transmitter is a single channel transmitter that reliably and accurately monitors toxic, oxygen, combustible, VOC or CO2 gas concentrations in potentially explosive and harsh environments, including classified hazardous rated areas. It can be connected to a controller (FCS), a control panel or a BAS / BMS / DDC system.

The colour, backlit LCD display changes with alarm status. Navigation through the menu is driven by a magnetic keypad and the user can change alarm set points, instrument configurations and enter into maintenance mode for non-intrusive calibration without opening the enclosure. The security menu allows entry of an authorization code to lock critical parameters.

It features non-volatile memory to store historical monitoring and calibration data and the real-time clock and calendar flag all alarm and calibration events. The CXT2 has the latest Smart Sensor technology and provides sensor life indications and smarter gas detection with simplified solutions and easy calibration. Optional features include an internal heater for low temperature applications.
