CAWT2102-wire conductivity, pH/ORP pIon transmitterMeasurement made easyIntroductionThis Operating Instruction provides installation,operation and maintenance procedures for theAWT210 2-wire transmitter. The transmitter is fullycompatible with ABB’s range of pH and redox (ORP)electrodes and with ABB’s range of 2-electrode,4-electrode and toroidal sensors. The transmitterhas automatic temperature sensor recognition forPt100, Pt1000 and 3k Balco RTDs in either 2-lead or3-lead configurations.The AWT210 transmitter is available with atraditional 4 to 20 mA output or with advanceddigital communications utilizing FOUNDATIONFieldbus (FF), PROFIBUS PA (PA) or HART. Thetransmitter is equipped with an LCD display used toshow the current process data and four keysbeneath the display enable the transmitter to beconfigured locally.For more informationFurther publications for the AWT210 transmitterare available for free download from:www.abb.com/measurementor by scanning this code:Links and reference numbers for the transmitterpublications are also shown below:Search for or click on:AWT210 transmitter –Data Sheet DS/AWT210-ENAWT210 transmitterCommissioning Instruction CI/AWT210-ENAWT210 transmitterCommunications Supplement COM/AWT210/HART-EN—AWT2102-wire transmitter
