The F12 Gas Transmitter is designed to measure toxic gas in hazardous locations requiring an Intrinsically Safe (IS) device. A non-IS version is also available for non-hazardous locations. Each version utilizes a digital communications protocol.
For many toxic gases, ATI offers a unique sensor response testing system unmatched by any competitive transmitter. Even outdoors in high wind conditions, the Auto-Test system provides reliable response checks to insure system integrity. Sensor response is verified with an actual gas sample, generated on demand. Generators store run time information accessible to operators, and are automatically tested for compatibility with the installed sensor.
F12 transmitters provide useful features that simplify installation, operation, and maintenance. The 4-button keypad is used to configure the menu-driven setup pages. The display also provides alarm indication and complete menus for setting up operating parameters.
The IS version of the transmitter is available with HART communications. The HART protocol supports the HART Universal and Common Practice Commands at 1200 baud using the Bell 202 FSK modem standard. The non-IS version of the transmitter is available with MODBUS communications. The MODBUS protocol supports 9600 baud access to concentration and status information, and supports alarm setup and many other functions on either RS485 or RS232 (software selectable).
