Critical Technical Advantages
-
IO-Link Digital Integration: By utilizing IO-Link technology, the TMT36 enables seamless digital communication from the sensor level to the control system. This allows for centralized parameterization, comprehensive diagnostic data, and simplified device replacement through automated data storage.
-
Configurable Switch Output: Beyond transmitting temperature data, the TMT36 features a versatile switch output. It can be configured as PNP, NPN, or push-pull, allowing the device to act as a local thermal switch for alarms or direct process control.
-
Superior RTD Accuracy: The transmitter improves measurement accuracy for RTD sensors down to 0.15 K. When used with sensor-transmitter matching via Callendar-van Dusen linearization, it eliminates the inherent interchangeability errors of sensors, providing high-tier precision for sensitive processes.
-
Modern Wiring with Push-In Terminals: The device is equipped with push-in terminals, facilitating fast and tool-free installation. This vibration-resistant connection method significantly reduces the time required for both initial setup and field maintenance.
-
Flexible Form Factors: While primarily designed to fit into a standard DIN Form B terminal head (flat face), the TMT36 can also be mounted on a DIN rail using a specific mounting clip, making it suitable for both field and cabinet installations.
-
Simple Parameterization: The transmitter can be easily configured using free software tools (paired with the SFP20 interface), allowing users to adjust ranges, switch points, and sensor types with minimal effort.
