Increased process reliability via drift monitoring
The TAD temperature sensor features a dual element sensing technology found in the sensor’s stainless steel sensing tip that contains two RTD sensing elements with opposite characteristics (positive resistance RTD vs. negative resistance NTC element) to detect drift. These two different measurement technologies react to temperature changes in opposite directions. Any deviation between the two process measurements indicates that a sensor drift is detected, allowing operators to immediately take action to solve process issues.
With this technology, the TAD provides long-term, highly accurate temperature indication in sanitary applications included in food, beverage and pasteurization processes.
Using LR Device software (Part No. QA0011), the drift warning and alarm levels can be easily set. Sensors can also be configured remotely using IO-Link, ifm’s digital communication interface. After the parameters are set, the TAD continuously self-monitors temperature drift. By providing immediate temperature drift detection, cyclical monitoring is no longer necessary.
