A12 The UniSens universal 2-wire gas transmitter handles 28 different gases, providing the most economical and flexible gas measurement system available today. Combining universal electronics, bench calibration capability, automatic sensor verification, fault detection and alarming, and superior sensor technology, UniSens is your best transmitter choice.

UniSens is designed for ambient gas monitoring in all kinds of industrial environments: gas storage areas, gas compressor rooms, process piping galleries, rail car sidings, analyzer shacks, gas cabinets, chemical process areas, and more.  In fact, the UniSens transmitter can be used most anywhere that hazardous gas conditions might develop either through leakage or through natural buildup.

ATI sensing modules consist of an electrochemical gas diffusion sensor and a solid state memory assembly.  Developed and manufactured exclusively by ATI, our electrochemical sensors provide excellent response time, maximum selectivity, and superior temperature stability for reliable gas sensing in a wide range of environments. The companion memory assembly stores operational information and calibration constants, along with gas sensor identification, sensing module range, and software revision level. Complete sensing modules are housed in convenient snap-in packages that mate easily with UniSens transmitters.

This unique combination of sensor and memory lets you calibrate sensing modules with any UniSens transmitter. So instead of calibrating in the field, you can bench calibrate sensing modules with a spare transmitter; once the sensors are snapped into a field transmitter, their calibration constants upload automatically.

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.
