Sensors take guess work out of temperature equations

Accurate and stable temperature measurement is vital for product quality in the food and beverage industry. But what happens to a product if the temperature measurement is inaccurate?

Temperature is one of the most important measurements where stability and accuracy of the process temperature is vital for proper product quality and safety.

The slightest deviation in product quality can cause great damage, such as the product recall of entire production runs, expensive downtime, as well as the damage to the brand’s reputation, which might never recover.

What if production managers and quality assurance could eliminate product quality risk caused by to inaccurate process temperature measurement between calibration cycles?
ifm’s process sensor portfolio has expanded to include analytical measuring sensors, which is highlighted with the newly released temperature calibration check (TCC) sensor.

The TCC technology is the sensor that checks itself and is specifically designed to combat the challenges of typical temperature products. ifm’s “Calibration Check” technology provides real-time continuous monitoring of instrument accuracy and measurement uncertainty. Smart diagnostic technology monitors accuracy with two measuring elements in the tip of the sensor to react to temperature changes. The microprocessor monitors for any potential decrease in measurement accuracy where the TCC’s repeatability is less than 0.015°C so users are assured the instrument provides repeatable measurements time after time.

The TCC sensor allows plant operators to take event-related measurements in case of drifts instead of waiting for the next planned calibration interval. This reduces the risk of losing entire production batches due to faulty production temperatures. The new TCC is designed to give users peace of mind that a product is monitored 24-hours a day and also monitors its own health and accuracy between calibration checks.

Due to the calibration check technology, the TCC permanently checks its own drift behaviour.

The sensor compares the temperature value to the simultaneously measured reference value. If the deviation is outside the tolerance range, which can be set between 0.5 and 3 K, the TCC provides an optical signal and sends a message to the central controller via IO-Link and the diagnostic output. The same applies to cases of serious malfunctions.

The TCC also automatically stores all the data required for consistent documentation via IO-Link with installation date, operating hours, temperature histogram, as well as logbooks on event messages.
