Critical Technical Advantages
-
Dual-Compartment Security: The housing is divided into two separate chambers—one for the electrical connections and another for the fully potted electronics and display. This design protects the sensitive circuitry from moisture, corrosion, and contamination during installation and maintenance.
-
Enhanced Local Visualization: The integrated backlit display provides a large, clear numerical reading, a bar graph for quick process overviews, and status condition icons. This allows field operators to assess the process health immediately without a handheld terminal.
-
High Safety and Isolation: Certified according to IEC 61508 for use in SIL applications, the TMT162 offers 2 kV galvanic isolation between the sensor input and the signal output. This ensures that electrical interference or ground loops do not compromise measurement integrity.
-
Universal Input Flexibility: A single device can be configured to handle RTDs, thermocouples, resistance (Ohm), or voltage (mV) signals. This versatility reduces spare part inventory and allows for standardized plant engineering.
-
Advanced Diagnostics: The transmitter provides comprehensive diagnostic information according to NAMUR NE107. Standardized symbols notify operators if the device requires maintenance, is out of specification, or has failed, facilitating rapid troubleshooting.
-
Robust Communication: Depending on your plant architecture, the TMT162 is available with HART, FOUNDATION Fieldbus (ITK 6.1.2), or PROFIBUS PA (Profile 3.02) protocols, allowing for seamless integration into major control systems.

Primary Applications
-
Harsh Process Areas: Monitoring temperatures in refineries, chemical plants, and offshore platforms where the device is exposed to salt spray, vibration, or extreme weather.
-
Hygienic Installations: The optional stainless steel housing version is perfectly suited for food, beverage, and life sciences applications requiring frequent washdowns.
-
Critical Safety Loops: Integrated into safety-instrumented systems (SIS) that require high-reliability temperature monitoring and documented safety performance.
-
Remote Monitoring: Using HART or Fieldbus protocols to configure and monitor sensors located in hard-to-reach areas of the plant.
-
Marine Applications: Certified for use on ships and offshore vessels for engine, cargo, and utility monitoring.
