Product Info

iTEMP TMT142
Endress+Hauser 5
Overranging Linear increase from 20.0 to 20.5 mA
Failure e.g. sensor failure; sensor short-circuit ≤ 3.6 mA ("low") or ≥ 21 mA ("high"), can be selected
The "high" alarm setting can be set between 21.5 mA and
23 mA, thus providing the flexibility needed to meet the
requirements of various control systems.
