Q&A
Q1: What types of sensors can I connect to the TMT82-BAA1EB1A1AAA1+E1?
A: The TMT82 features 2 universal inputs that accept a wide range of sensors . For RTDs, it supports Pt100, Pt200, Pt500, Pt1000, Ni100, Ni120, Cu50, and Cu100. For thermocouples, it supports Types K, J, N, S, R, E, T, B, C, D, and L. It also accepts direct resistance (Ω) and voltage (mV) inputs. The two channels are independent but must use the same measurement unit (e.g., both °C) .
Q2: What is the accuracy of the TMT82, and is it certified for safety applications?
A: For Pt100 sensors over -50 to 200°C, the TMT82 delivers ≤ 0.1 K accuracy . It is certified for SIL 2 / SC3 according to IEC 61508:2010, making it suitable for use in safety instrumented systems . The device also features sensor and hardware failure detection with diagnostics according to NAMUR NE 107.
Q3: What mounting options does the TMT82 offer, and how easy is it to install?
A: This specific version (B housing) is a head transmitter designed for mounting in terminal heads per DIN EN 50446 . Alternative versions are available for DIN rail mounting (17.5 mm width) or field housing. Installation is simplified by push-in terminal technology for tool-free wiring on select versions . The HART protocol enables easy configuration using FieldCare, DeviceCare, or handheld communicators .
