UniSens - Gas Monitors and Water Quality Monitors

1 Universal 2-Wire Gas World of Single Transmitter Is All You was, monitoring multiple gases meant using differentgas transmitters each with its own maintenanceproblems, its own appetite for spare parts, its owninstallation headaches, and so on, and so again, thanks to ATI. Our UniSens universal 2-wiregas transmitter handles 28 different gases, providing themost economical and flexible gas measurement systemavailable today. Combining universal electronics, benchcalibration capability, automatic sensor verification, faultdetection and alarming, and superior sensor technology, UniSens is your best transmitter is designed for ambient gas monitoring in allkinds of industrial environments: gas storage areas, gascompressor rooms, process piping galleries, rail car sidings,analyzer shacks, gas cabinets, chemical process areas, fact, the UniSens transmitter can be used mostanywhere that hazardous gas conditions might developeither through leakage or through natural buildup.

Sensor Keepers are useful notjust for transporting sensors to and from the field, but forkeeping calibrated spares on the shelf. They also let uscalibrate sensors at the factory, and ship them forimmediate installation and Sensing ModulesATI sensing modules consist of an electrochemical gasdiffusion sensor and a solid state memory and manufactured exclusively by ATI, ourelectrochemical sensors provide excellent response time,maximum selectivity, and superior temperature stability forreliable gas sensing in a wide range of environments.

3 Thecompanion memory assembly stores operationalinformation and calibration constants, along with gassensor identification, sensing module range, and softwarerevision level. Complete sensing modules are housed inconvenient snap-in packages that mate easily with unique combination of sensor and memory letsyou calibrate sensing modules with any UniSenstransmitter. So instead of calibrating in the field, you canbench calibrate sensing modules with a spare transmitter;once the sensors are snapped into a field transmitter, theircalibration constants upload automatically.* Indicates Auto-Test *0-100 PPM50/500 PPMC arbon Monoxide*0-100 PPM50-500 PPMH ydrogen0-4%2000 PPM/10%Nitric Oxide0-50 PPM25/500 PPMO xygen0-25%10/100%Phosgene0-1 PPM1/100 PPMB romine*0-1 PPM1/100 PPMC hlorine0-10 PPM1/100 PPM Chloride Dioxide*0-1 PPM1/100 PPMF luorine*0-1 PPM1/100 PPMH ydrogen Peroxide0-10 PPM10/100 PPMI odine*0-1 PPM1/100 PPMO zone*0-1 PPM1/100 PPMH ydrogen Chloride* 0-20 PPM 10/200 PPMH ydrogen Cyanide*0-20 PPM10/200 PPMH ydrogen Fluoride*0-20 PPM10/200 PPMH ydrogen Sulfide*0-50 PPM10/500 PPMN itrogen Dioxide*0-20 PPM5/200 PPMS ulfur Dioxide*0-20 PPM10/200 PPMA rsine0-1000 PPB1000 PPB/100 PPMD iborane0-1000 PPB1000 PPB/100 PPMG ermane0-1000 PPB1000 PPB/100 PPMH ydrogen Selenide0-1000 PPB1000 PPB/100 PPMP hosphine0-1000 PPB1000 PPB/100 PPMS

Available on many ATI sensingmodules, our optional Auto-Test gas generator can cuttesting costs dramatically by automatically verifyingsensor s a simple system. The Auto-Test gas generator iscoupled to the end of the sensor as an integral part ofthe sensing module. Every 24 hours, the transmitteractivates the generator and Monitors the sensor forresponse. If the sensor responds properly, the systemreverts to normal operation; if it fails, output is driven mA to signal trouble.

5 (During testing, the outputsignal is held at the pre-test value.)The transmitter maintains a log of completed tests,and can display the time until the next scheduled operator can manually activate Auto-Test, Transmitter ModuleThe UniSens microcomputer-controlled transmitterprovides a local digital display and a 4 20 mA analogoutput proportional to gas concentration. It works withany ATI sensing module, configuring its own displayand output range automatically based on data readfrom the module s memory. Zero and calibration data isalso read into memory, so the transmitter isautomatically calibrated when it s connected to acalibrated controls on the front of the transmitterallow field calibration, manual activation of the Auto-Test feature (if installed), and review of sensingmodule data including gas type, range, and number ofsuccessful Auto-Tests.
