المزايا التقنية الحاسمة
-
PC Programmable Versatility: Unlike fixed-range transmitters, the TMT80 is fully configurable via a PC using the ReadWin 2000 software and a configuration kit. This allows you to adjust the sensor type and measuring range to meet the specific needs of your application.
-
Universal Input Support: The device supports both selected Resistance Temperature Detectors (RTD) and common thermocouples (TC). To ensure maximum precision, the transmitter stores specific linearization characteristics for every supported sensor type.
-
Standardized 2-Wire Technology: Operating on a 2-wire 4 to 20 mA loop, the TMT80 simplifies wiring and reduces installation costs by using the same two wires for both power and signal transmission.
-
Safety and Error Handling: Presettable to NAMUR NE 43 standards, the transmitter provides reliable fault signaling. In the event of a sensor break or short circuit, the output signal is driven to a predefined error level, alerting the control system immediately.
-
Galvanic Isolation: The TMT80 features 500 V galvanic isolation between the input and output. This isolation protects the connected control equipment from electrical noise and potential interference originating at the sensor.
-
EMC Compliance: The device meets the electromagnetic compatibility (EMC) requirements of NAMUR NE 21, ensuring stable performance in electrically “noisy” industrial environments.
Understanding FLEX
In the context of Endress+Hauser’s temperature portfolio, FLEX refers to a simplified selection and ordering philosophy. It stands for products that are:
-
Easy to Select: Narrowed down to the most essential features to prevent over-engineering.
-
Easy to Install: Standardized dimensions and wiring for quick setup.
-
Easy to Operate: Straightforward software interfaces for quick configuration.
The TMT80 is a core component of this “Simple Product” range, focusing on the fundamental needs of the industry without unnecessary overhead.
