Technical data iTEMP TMT71
48 Hauser
Current consumption • 3.6 to 23 mA
• Minimum current consumption 3.5 mA
• Current limit ≤ 23 mA
Terminal Choice of screw terminals or push-in terminals for sensor and power supply cables:
Terminal design Cable version Cable cross-section
Screw terminals Rigid or flexible ≤ 2.5 mm² (14 AWG)
Push-in terminals (cable version,
stripping length = min.
10 mm (0.39 in)
Rigid or flexible 0.2 to 1.5 mm² (24 to 16 AWG)
Flexible with wire end ferrules
with/without plastic ferrule 0.25 to 1.5 mm² (24 to 16 AWG)
Ferrules must be used with push-in terminals and when using flexible cables with a
cable cross-section of ≤ 0.3 mm 2 . Otherwise, the use of ferrules when connecting
flexible cables to push-in terminals is not recommended.
13.4 Performance characteristics
Response time
Resistance thermometer (RTD) and resistance
transmitter (Ω measurement) ≤1 s
Thermocouples (TC) and voltage transmitters (mV) ≤ 1 s
Reference temperature ≤ 1 s
When recording step responses, it must be taken into account that the times for the
internal reference measuring point may be added to the specified times.
Reference operating
conditions
• Calibration temperature: +25 °C ±3 K (77 °F ±5.4 °F)
• Supply voltage: 24 V DC
• 4-wire circuit for resistance adjustment
Maximum measured error In accordance with DIN EN 60770 and the reference conditions specified above. The
measured error data correspond to ±2 σ (Gaussian distribution). The data include non-
linearities and repeatability.
MV = measured value
LRV = lower range value of the sensor in question
