The Series 3500 Smart Differential Pressure Transmitter is a microprocessor-

based high performance transmitter, which has exible pressure calibration, push button conguration, and programmable using HART® Communication. The Series 3500 is capable of being congured for differential pressure or level applications with the zero and span buttons. A eld calibrator is not required for conguration. The transmitter software compensates for thermal effects, improving performance. EEPROM stores conguration settings and stores sensor correction coefcients in the event of shutdowns or power loss. The Series 3500 can be congured to be ATEX or IECEX approved for use in hazardous (classied) locations. The rangeability allows the smart transmitter to be congured to t any application.
