Temperature Transmitters TF02/TF02-Ex (head mounted) and ...

Mounting3.2.2 Sensor interfaceSensor conduits are connected to the screw terminals of the TF02 for pipe cross-sections of up to 2.5 mm² (withwire end ferrules).DANGERUse only the supplied threaded screws M3 × 6 mm. The use other, longer screws can lead to transmitterdamage. In case of ex-proof transmitters, this would nullify the explosion protection.2431Fig. 3-12Top view of the transmitter TF02+-OutputFoundationFieldbus (H1)MicroprocessorReferencejunction Pt 100Input134213421 13 3ϑ ϑ ϑ4 42 2Resistance sensors/Potentiometer1 1 1ϑCh1334ϑCh22 2 213421Ch134Ch22Thermocouples/Voltages1 1 1 13Ch134Ch223Ch134Ch22CombinationResistancesensor/Thermocouple1Ch134Ch22ϑa) b) c) d) e) f) g) h) i) j)k) l) m)Fig. 3-13 Sensor connection TF02/ TF202a) Resistance thermometer, 2-wire circuitb) Resistance thermometer, 3-wire circuitc) Resistance thermometer, 4-wire circuitd) Double resistance thermometer, 2-wire circuitPotentiometer: 0...500 Ω or 0...4000 Ωe) Potentiometer, 2-wire circuitf) Potentiometer, 3-wire circuitg) Potentiometer, 4-wire circuith) 2 Potentiometer, 2-wire circuiti) Thermocouplej) Double thermocoupleVoltages: -75 mV...+75 mV or -120 mV...+1200 mVk) Voltage measurementi) 2-fold voltage measurementm) Combination thermocouple and resistance thermometer42/11-51 EN Temperature Transmitters TF02/TF02-Ex (head mounted) and TF202/TF202-Ex (field mounted) 13
