INSTRUMENT DESCRIPTION
General description
ATT1/ATT1-I is a signal transmitter (Not insulated/Insulated)
capable of accepting in input various types of sensors and
retransmitting their signals with a programmable range.
The transmitter accepts input signals from:
Pt100
Measuring range: -200... +800°C, type of connection:
2, 3, 4 wires, accuracy: 0.1% fs ±10 μA;
Pt1000
Measuring range: -200... +800°C, type of connection:
2 wires, accuracy: 0.1% fs ±10 μA;
Ni100
Measuring range: -60... +180°C, type of connection:
2, 3, 4 wires, accuracy: 0.5% fs ±10 μA;
TC B
Measuring range: 40... 1820°C, the accuracy: 0.2% fs ±10 μA
(only in the range 900... 1800°C);
TC E
Measuring range: -200... +940°C, accuracy: 0.2% fs ±10 μA;
TC J
Measuring range: -200... +1200°C, accuracy: 0.2% fs ±10 μA;
TC K
Measuring range: -200... +1340°C, accuracy: 0.2% fs ±10 μA;
TC N
Measuring range: -200... +1280°C, accuracy: 0.2% fs ±10 μA;
TC R
Measuring range: -40... +1760°C, accuracy: 0.2% fs ±10 μA
(
only in the range 400... 1760°C);
TC S
Measuring range: -40... +1760°C, accuracy: 0.2% fs ±10 μA
(
only in the range 400... 1760°C);
TC T
Measuring range: -200... +400°C, accuracy: 0.2% fs ±10 μA
(
only in the range
-100... +400°C);
mV
Measuring range: -10... +70 mV, accuracy: 0.1% fs;
Potentiometer 10... 400 Ω
type of connection: 2, 3, 4 wires;
accuracy: 0.1% fs ±10 μA;
Poteniometer 10... 4000 Ω
type of connection: 2 wires,
accuracy: 0.1% fs ±10 μA.
It transmits, on the output,
4... 20 mA
current signals.
The transmitter can be programmed using an Android Smart-
phone equipped with the NFC functionalities (Near Field Commu-
nications) and the APP ATNfc (available, free of charge, on Google
store) or using a PC with the AFC1 transmitter and the ATNfcSoft
program (downloadable, free of charge, from our Internet site).
