iTEMP - Model TMT125 -DIN Rail Temperature Transmitter
Transformation of sensor signals into standardized digital output signals for all industries. Unsurpassed reliability, accuracy and long-term stability in critical processes over all industries. The configurable transmitter not only transfers digital converted signals from RTD and TC sensors, it also transfers resistance and voltage signals using FOUNDATION Fieldbus™ communication. High measurement point availability by means of sensor monitoring functions and device hardware fault recognition. Optionally, installation on DIN rail according to IEC 60715 or in a field housing.
