Critical Technical Advantages
-
Automated Inline Self-Calibration: The TM371 performs a calibration check every time the process temperature crosses the Curie point of its internal reference material (typically during SIP or high-temperature cleaning). This process is fully autonomous and requires no manual intervention, providing a traceable “Pass/Fail” result for every event.
-
The Curie Effect Reference: The device contains a built-in, long-term stable reference based on a physical constant (the Curie temperature). This provides a fixed point traceable to the International Temperature Scale of 1990 (ITS-90), ensuring the highest level of measurement integrity.
-
Heartbeat Technology: Beyond self-calibration, Heartbeat Technology provides continuous self-diagnostics and verification of the entire instrument’s health. It identifies issues before they lead to failure, supporting predictive maintenance strategies.
-
Audit-Proof Documentation: The transmitter features an internal memory capable of storing up to 350 calibration events. These records can be retrieved at any time to generate printable, audit-proof calibration certificates, either locally or through Netilion cloud-based systems.
-
Individual Transmitter-Sensor Matching: From the factory, each TM371 undergoes a matching process where the transmitter is tuned to the specific linearization curve of its RTD element. This eliminates the standard interchangeability error, resulting in superior measurement precision.
-
Seamless Digital Integration: The TM371 supports 4 to 20 mA and HART communication as standard. With the addition of a FieldPort SWA50, it can also provide secure Bluetooth and WirelessHART connectivity for remote monitoring in complex plant environments
