The TTH300 HART temperature transmitter in proven 2-wire technology features a multitude of new functions and enhanced diagnostic information. The temperature transmitter can be configured using the DSV401 (SMART VISION) device management tool or via FDT/DTM technology. The TTH300 is based on the latest technology and by 2008 will replace the proven head mounted TH02 transmitters first introduced in 1998.
