Critical Technical Advantages
-
Wireless Operation via Bluetooth: The TMT72 features a built-in Bluetooth interface, allowing you to configure parameters and view real-time measured values through the SmartBlue app. This is a game-changer for transmitters mounted in difficult-to-reach terminal heads or hazardous areas, as it eliminates the need for physical connection cables.
-
Universal Input Flexibility: One device handles it all. Whether you are using Resistance Temperature Detectors (RTD), thermocouples (TC), or simple Ohm/mV signals, the TMT72 can be scaled and programmed to fit the specific needs of your measuring point.
-
Enhanced Measurement Accuracy: Through sensor-transmitter matching, you can calibrate the transmitter to the specific mathematical characteristics of your sensor. This process eliminates the inherent “interchangeability error” of standard sensors, resulting in significantly higher system accuracy.
-
Smart Monitoring and Diagnostics: Following the NAMUR NE 107 standard, the TMT72 provides clear diagnostic status signals. It continuously monitors both the sensor (detecting breaks or short circuits) and its own internal hardware, ensuring that any issues are reported before they impact your process.
-
Modern Wiring Technology: The transmitter is equipped with push-in terminals. This allows for fast, tool-free wiring, which reduces installation time and provides a highly vibration-resistant connection compared to traditional screw terminals.
-
Versatile Mounting Options: The TMT72 is designed to fit a variety of installation needs:
-
Head Mount: Standard DIN Form B flat-face terminal heads.
-
DIN Rail: For organized cabinet mounting.
-
Field Housing: Can be mounted in a separate field enclosure for direct outdoor use or Ex d (explosion-proof) applications.

Digital Plant Upgrades: Ideal for facilities looking to implement wireless configuration and mobile asset management.
-
Hazardous Area Monitoring: Safe and reliable operation in explosive atmospheres, supported by international approvals (ATEX, IECEx, FM, CSA).
-
High-Accuracy Loops: Critical temperature points in the food, pharma, or chemical industries where sensor-transmitter matching is required for tight process control.
-
Cabinet and Field Integration: Flexible enough to be used in centralized control cabinets on DIN rails or distributed throughout the field in terminal heads.
-
Routine Maintenance: Using the SmartBlue app to quickly verify device health and calibration without opening the housing or interrupting the loop.
