The Series F12 Ozone Transmitter is an Intrinsically Safe (IS) version of our explosion proof D12 transmitter. There are 4 different ozone sensor ranges to choose from.  See below for details.

There are 4 available ozone sensors to choose from:

0-1000 ppb

• 0-1000 ppb standard range
• 0-500 ppb minimum range
• 0-2000 ppb maximum range
• Units of measure = ppb (parts per billion)
• 1 ppb resolution

 0-2 ppm

• 0-2 ppm standard range
• 0-1 ppm minimum range
• 0-5 ppm maximum range
• Units of measure = ppm (parts per million)
• 0.01 ppm resolution

 0-20 ppm

• 0-20 ppm standard range
• 0-5 ppm minimum range
• 0-200 ppm maximum range
• Units of measure = ppm (parts per million)
• 0.1 ppm resolution

 0-1,000 ppm

• 0-1,000 ppm standard range
• 0-200 ppm minimum range
• 0-1,000 ppm maximum range
• Units of measure = ppm (parts per million)
• 1 ppm resolution

In standard form, the F12 is designed for ozone gas detection in hazardous area applications requiring IS devices.  In addition, it is also well suited for all general purpose applications where toxic gas measurement is required.  For IS installations, this transmitter is also available with a Hart communication option.

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 trasmitter.  Calibration data is read into the transimtter automatically and no other adjustments are normally required.  In addition to ozone, there are over 30 other gas sensors available to be used with the F12.  See below or click here for full list.

For gernal purpose gas detection applications, the F12 transmitter is also available in Non-IS version.  One version provides for easy interfact to RS-484 networks using a standard MODBUS communication protocol.  A second version provides a complete AC powered instrument with 3 alarm relays (SPST) availbale for exteral alarming.

F12 Options (how to order)

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

     -Remote Sensor holder with Junction box allows for a remote mount sensor at a max length of 100 feet.  Standard option includes 100 feet of cable, if shorter cable length is preffered custom lengths can be provided.

     -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.

Digital Output:

     -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 VAC sensors. 

F12 Features

Intrinsically Safe Design: Transmitters are designed for use in applications requiring intrinsically safe devices for safety purposes.

Interchangeable Sensors: Every transmitter will accept up to 45 different sensor modules, greatly reducing the need for multiple transmitter models.

Sensor Auto-Test: ozone 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 setpoint, hysteresis, on-delay, off-delay, and other variables. Systems with alarms are available for operation from 12-30 VDC supplies or from 115 or 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: ozone 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 ozone 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.

F12 Accessories

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.

F12 Specifications

Ozone Sensor Cross Sensitivities

     -Chart below shows the gasses that are cross sensitive and will create a false response to the H10 Ozone Sensor.

     -Note: 0-1000 ppm low range ozone sensor (H10-14) may exhibit low response to certain other gases not listed.  When applying this sensor to specific applications, it is good practice toverify whether or not any of these potential interferences are present and might present interference issues. 

     -Cross-sensitifity data is approximate and based on exposure under 100 ppm.

Calibration information

ATI Specific Calibration Information

Auto-test Generator

The Auto-test option verifies the serviceability of the transmitter on a prescribed schedule by exposing the sensor to a small amount of ozone, 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 a E18 ozone generator, which must be compatible with the installed sensor’s gas type, and full-scale range. Table below lists gas compatible generators and sensors.

Sensors

We provide each sensor with a standard detection range.  However, for specific applications each sensor can be calibrated to custom ranges.  See list below for min, and max range options for each sensor, along with standard range.

Please contact us with any questions on what sensor might be right for you, or if other sensors are available for your application.
