iTEMP - Model TMT142 -Temperature Field Transmitters
Transformation of sensor signals into stable and standardized output signals for all industries. Unsurpassed reliability, accuracy and long-term stability in critical processes over all industries. The configurable transmitter not only transfers converted signals from RTD sensors and thermocouples, but also resistance and voltage signals using HART® communication. It visualizes the signals on its own backlit display. A rugged field housing allows a direct connection in the process areas. Moreover, a swift and easy operation and maintenance can be realized by PC using operating software.
