Critical Technical Advantages
-
Automated In-Situ Self-Calibration: The TM372 eliminates the risk of undetected sensor drift by performing a calibration check automatically during the process. This provides 100% transparency between manual calibration intervals and removes the human error associated with traditional verification methods.
-
Heartbeat Technology: This integrated diagnostic suite provides continuous monitoring of the device’s “health.” It allows for a documented verification of the instrument’s performance without interrupting the 4 to 20 mA loop, supporting proactive maintenance and reducing the risk of non-conformities.
-
Automated 4 to 20 mA Loop Check: The TM372 includes a specialized function to verify the integrity of the entire signal loop. This saves significant commissioning time and ensures that the temperature value reaching the control system is perfectly synchronized with the sensor’s output.
-
Audit-Proof Documentation: With an internal memory that stores the last 350 calibration events, the device provides a robust data trail for quality audits. Calibration certificates can be generated and printed at any time, proving that the sensor was accurate at the time of the production batch.
-
Elite Measurement Accuracy: Each TM372 undergoes individual sensor-transmitter matching at the factory. By programming the specific Callendar-Van Dusen coefficients of the RTD element into the transmitter, the standard “interchangeability error” is eliminated, providing the highest possible precision for sensitive thermal processes.
-
Global Hygienic Compliance: The probe is designed for the strictest sanitary environments, carrying approvals such as EHEDG, 3-A, ASME BPE, and FDA. Its stainless steel construction and IP69 rating make it fully resistant to aggressive cleaning agents and high-pressure washdowns.
