Temperature transmitter ABB Instrumentation Analysis

The compact and robust field mounted termperature transmitters of this new series from ABB are accommodated in field housings with optional indicators. Besides the analog and digital indicators a CoMeter - i.e. a HART-compatible configurator - is available. The CoMeter permits to configure a HART-programmable transmitter in the control loop.

The field housings of the transmitter are either made of aluminum die cast or of stainless steel. The rating plates are made of stainless steel. The devices are available with a tube mounting kit or a wall mounting kit.

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.
