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. Features and Benefits:Universal sensor input (RTD, thermocouple, Ohm, mV) Various sensor error-calibration possibilities (one point, two point, Calendar-van-Dusen) Sensor Backup / autom. Sensor redundancy switching (2 x Pt100 3-wire connection) Freestyle characteristics (32 supporting points) Output signal (temperature linear), 4 … 20 mA, HART signal Accuracy 0.1 %, long-term stability 0.05 % per year IP 66 / IP 67, NEMA 4X aluminum or stainless steel field-mount housing Transmitter-controlled LCD display with TTF300 configuration options
