2 Function and system design Measuring principle Measuring system Electronic monitoring and conversion of input signals in industrial temperature measurement. The itemp RTD DIN rail TMT 127 DIN rail temperature transmitter is a 2-wire transmitter with analog output, measuring input for Pt100 in 2, 3, or 4-wire connection. Input values Measured variable Measuring range Input type Temperature Depending on the application, different measuring ranges can be ordered (see Product structure ). Input Designation Measuring range limits Min. span Resistance thermometer (RTD) Pt100 as per IEC to 1562 F (-200 to 850 C) 18 F (10 C) Type of connection: 2, 3 or 4-wire connection Cable resistance: sensor cable resistance of max. 40 per cable Sensor current: 0.6 ma Output values Output signal Analog 4 to 20 ma Breakdown information Breakdown information to NAMUR NE 43 Breakdown information is created when the measuring information is invalid or not present anymore and gives a complete listing of all errors occuring in the measuring system.
