Description
PC-programmable temperature transmitter for head and DIN rail mounting.
Description
The iTEMP TMT181 and TMT121 are programmable 2-wire temperature transmitters suitable for resistance elements (RTDs) in 2, 3 or 4-wire technology and for 12 different thermocouples. The configuration can be carried out quickly and simply online with the aid of a PC using the
ReadWin 2000 operating software that includes a signal interface. This interface (TMT181A) can be connected to head transmitter TMT181 or to the front of the TMT121.
Both are galvanically isolated as standard, have sensor monitoring in accordance with NAMUR NE43, EMC in accordance with NAMUR NE21, output simulation and the possibility of sensor-specific linearisation. Intrinsically-safe and 3G (for zone 2) versions are available with ATEX certificate as an Ex version.
