Smart Head-Mounted HART Temperature Transmitter

The Maxwell TME310-A0NN Series is an advanced, highly reliable head-mounted smart temperature transmitter designed for universal industrial applications. Engineered to fit standard DIN B connection heads, this loop-powered device seamlessly converts signals from a wide array of sensors — including RTDs, Thermocouples (TC), resistance, and voltage (mV) inputs — into a stable, scalable 4-20mA analog output superimposed with the HART 7 digital communication protocol.

Equipped with a clear, rotatable 4-digit LCD display and an intuitive 3-button interface, the TME310 allows for effortless local configuration and real-time process monitoring without the need for external communicators. Its robust design ensures exceptional measurement accuracy (±0.1°C typical for Pt100), outstanding long-term stability, and comprehensive diagnostic capabilities compliant with NAMUR NE 107 standards. Whether configured locally, via a HART handheld device, or through PC software, the TME310 delivers precise, dependable temperature measurement for the most demanding process control environments.

Universal Sensor Input	Fully compatible with 2/3/4-wire RTDs (Pt100, Pt1000, Ni100, Cu50, etc.), Thermocouples (Type B, E, J, K, N, R, S, T), linear resistance (0–2000 Ω), and millivolt signals (−10 to +100 mV).
HART 7 Communication	Features a 2-wire 4-20mA analog output integrated with the latest HART 7 digital protocol for advanced remote configuration, asset management, and diagnostics.
Integrated LCD Display	Built-in 4-digit LCD screen provides clear, real-time visualization of process values, engineering units (°C/°F/K), and diagnostic error codes.
Local Push-Button Configuration	Three integrated push-buttons (MENU, ◄, ▲) enable quick and easy on-site parameter setup without requiring a HART modem or handheld communicator.
High Precision & Stability	Delivers a reference accuracy of ±0.1°C (for Pt100) with exceptional long-term stability (±0.1°C/year) and a rapid response time of less than 1 second.
Advanced Diagnostics	Incorporates continuous sensor open/short circuit detection, out-of-range monitoring, and internal electronics failure detection per NAMUR NE 107.
Rotatable Display Module	The display can be rotated in 4 × 90° increments to ensure optimal readability regardless of the installation orientation within the DIN B head.
Robust Protection	Features reverse polarity protection, EMC compliance (EN 61326-1, NAMUR NE 21), and a wide operating temperature range of −40°C to +85°C.
