For enhanced (e.g. redundancy) field mounting application with 4…20 mA HART, Profibus and Foundation Fieldbus communication. With and without display including device configuration (HMI). Also available with Ex-approvals and SIL certificates
The TTF300 HART temperature transmitter in proven 2-wire technology features a multitude of new functions and enhanced diagnostic information.
The driver-independent configuration possibilities of the TTF300 are new and unique through the LCD display controlled by temperature transmitter and the DSV401 (SMART VISION) device management tool or the FDT / DTM technology.
The TTF300 is based on the latest technology and by 2008 will replace the proven head-mounted TH202 transmitters first introduced in 1998.
