The Series F12 Gas Transmitter is well suited for all general purpose applications where toxic gas measurement is required.
F12 Transmitters use ATI's standard smart sensors for maximum flexibility. Sensors are easily exchanged and contain all calibration constants in sensor memory, eliminating the need for field calibration of transmitters. Sensors may be calibrated separately on the bench and then simply plugged into the transmitter. Calibration data is read into the transmitter automatically and no other adjustments are normally required.
For Intrinsically Safe (IS) applications, the F12 transmitter is available as an F-12is version. One version provides for easy interface to RS-484 networks using a standard MODBUS communication protocol. A second version provides a complete AC powered instrument with 3 alarm relays (SPST) available for external alarming

Sensor Holder Style:
The sensor of the F12 can be mounted in a variety of ways
- Integral sensor is standard and contains the standard sensor holder integrated into the enclosure of the F12 out the bottom of the enclosure
- Remote sensor holder with 6 foot cable provides a remote mount sensor in a pre-wired 6'cable, this cable length is fixed and cannot be changed

- Duct mount sensor holder provides a duct mount sensor for duct, or pipe mount application and a duct mount adapter. Also includes 25 feet of cable for remote mounting ability.
- Heated sensors are optional - please contact us to configure as they are very customizable.
- Standard 4-20 mA output is provided with all sensors
- HART interface is available for all sensors
- Modbus interface is only available for RS-485 sensors, and 115-230 VAC sensors.
Interchangeable Sensors: Every transmitter will accept up to 45 different sensor modules, greatly reducing the need for multiple transmitter models.
Sensor Auto-Test: Gas generators permanently installed on the sensor verify sensor operation by providing a “bump test” of the sensor from daily to once a week.
Smart Sensor Modules: Plug-in sensors store calibration data, allowing sensors to be calibrated separately from the transmitter. This allows bench calibration (or factory calibration) of sensors to reduce the necessity for carrying calibration gas around the plant.
Alarm & Relay Option: A non-IS version of the transmitter provides 3 integral alarm relays. Relays are programmable for set point, hysteresis, on-delay, off-delay, and other variables. Systems with alarms are available for operation from 12-30 VDC supplies or from 115-230 VAC power.
Serial Communication Interface: 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 versions of the transmitter are available with MODBUS™ communications. The MODBUS protocol supports 9600 baud access to concentration and status information, and supports alarm setup and many other functions.
LCD Graphics Display: Gas Concentrations are displayed in large, easy to read numbers. The display also provides alarm indication and complete menus for setting up operating parameters.
Internal Data Logger: Measured gas values are stored at user definable intervals and can be recalled when needed on the LCD display. Data can be downloaded using a HART™ or MODBUS™ interface.
Sensor Calibration History: Each time a sensor is zeroed or calibrated, the data is stored in memory. Calibration history can be recalled and sensor condition reviewed by operating personnel whenever necessary.
Non-Intrusive Operation: Operating functions such as calibration, alarm setup, alarm reset, data view, and setup options are all available using sealed front panel switches on the face of the Nema 4X transmitter enclosure.
Heated Sensor Option: For use in applications where condensation is a problem, this heater option keeps the sensor above the dew point to eliminate loss of sensitivity due to moisture blockage on the sensor face.
Output Simulation: Transmitter analog output can be set to user definable values and relay outputs can be set to specific states for complete simulation of detection system operation. Output and alarms may also be inhibited for maintenance and calibration.

Calibration Adapter: The F12 can be calibrated by performing a zero calibration, and then the calibration adapter is required.
Flowcell Assembly: Allows the F12 to measure a sample gas flowing past the sensor. Sealed flowcell assembly is safe to use and provides accurate gas measurement of sample gas. Use in sample stream with a sample pump or sampler (example: A21 Gas Sampler)
Sensor Module Keeper: Can hold up to 4 sensors and keeps them ready for operation so complete sensor changes and sensor warm-up can be made in less than 1 minute.
Duct Sensor Adapter: Allows the sensors to be held in this adapter, and then secured to a duct or pipe. It has a 1 1/2" MNPT connection.
Panel Mount Bracket: Can be used to panel mount the F12. NOTE: this comes with the standard F12.
RAP-1: Alarm panel that offers visual and audible alarms to indicate gas levels that are unsafe.
RAP-2: Alarm panel that offers visual and audible alarms to indicate when Ozone levels are unsafe.

The Auto-test option verifies the serviceability of the transmitter on a prescribed schedule by exposing the sensor to a small amount of gas, and verifying a minimum response. Three attempts per test are made, and if the sensor does not respond on the third attempt, a fault alarm is triggered (may be optionally disabled).
The test is performed at a specific time of day, and may be scheduled to repeat every 1 to 14 days. The date and time of the next test is available for editing, and the test may be triggered manually at any time, without affecting the preset schedule.
The Auto-test option requires an E18 gas generator, which must be compatible with the installed sensor’s gas type, and full-scale range. Table below lists gas compatible generators and sensors.
