3 It has measurement input for resistance thermometers (RTD) in 2-, 3- or 4-wire connection, thermocouples and voltage transmitters. Setting up of the TMT 182 is done using the HART -Protocol with hand operating module (DXR 275) or PC (COMMUWIN II).InputMeasured variableTemperature ( Temperature linear transmission behaviour), resistance and voltageMeasuring rangeThe transmitter records different measuring ranges depending on the sensor connection and input of inputResistance thermometer (RTD)TypeMeasurement rangesmin. meas. rangePt100Pt500Pt1000acc. to IEC 751-200 to 850 C (-328 to1562 F)-200 to 250 C (-328 to 482 F)-200 to 250 C (-238 to 482 F)10 K10 K10 KNi100Ni500Ni1000acc. to DIN 43760-60 to 250 C (-76 to 482 F)-60 to 150 C (-76 to 302 F)-60 to 150 C (-76 to 302 F)10 K10 K10 K Connection type: 2-, 3- or 4-wire connection Software compensation of cable resistance possible in the 2 wire system(0 to 30 ) Sensor cable resistance max.
