Measuring range
Electronic recording and conversion of Pt100 input signals in industrial temperature measurement.
The iTEMP TMT180 temperature head transmitter is a two-wire transmitter with an analog output
and measurement input for Pt100 in 2-, 3-, or 4-wire connection. The device is set up using a
configuration kit and the ReadWin 2000 operating software which is free-of-charge.

The data relating to the measured error are typical values and correspond to a standard deviation of
± 3σ (normal distribution), i.e. 99.8% of all measured values achieve the specified values or better
values. Percentage values refer to the set span. The larger value is valid.
