Turck IM34-11EX-I 7506630 Temperature Measuring Amplifier Input For Pt100 Ni100 Resistors 4…20 mA

1. Overview of the Turck IM34-11EX-I 7506630

The Turck IM34-11EX-I 7506630 is a temperature measuring amplifier. It instantly converts microvolt signals from Pt100, Ni100, or thermocouples in hazardous areas into a universal current of 4–20 mA. Its ±0.1% accuracy allows precise measurement of every degree within the 0-1990°C range. Its eight international explosion-proof certifications, including ATEX, IECEx, and UL, ensure rock-solid stability even in Zone 2, eliminating the need for on-site wiring in explosion-proof enclosures.
