Discover TCC
Are you confident in your temperature instruments?
Temperature is one of the most crucial measurements used in process control. In the food and beverage sectors, precise and stable temperature measurement is essential for ensuring product quality and safety. But, what happens if your process temperature is inaccurate?
Thermal shock impact on drift and sensor lifespan
CIP processes are among the most severe conditions to which instruments are exposed. The constant cycling between hot and cold temperatures can rapidly cause fatigue in the electronic components and, consequently, lead to drift and malfunction. Every CIP cycle is a potential source of drift.
We simulate CIP in our thermal shock chamber. Instruments are fully submerged in a bath at -15 °C for 10 minutes and then transferred immediately (< 10 seconds) to another bath at 140 °C. We test for drift after every 50 cycles at a measured temperature of 123 °C.
The chart shows the results for each manufacturer. The last measurement shown for Manufacturers B and C is the point where each unit failed. Note that there is no data shown for Manufacturer A, since their products failed after two thermal cycles. The TCC measurement drifted < 0.2 °C and it did not fail even after 1000 cycles, at which point we stopped the test.
Flow velocity impact on weld integrity
ifm tests resistance to fatigue failure due to mechanical bending forces caused by high-velocity flow and water hammer. The test simulates the forces experienced in pipes and measures the fatigue strength of the laser weld between the process connector and the tube of the probe. Most manufacturers recognize this weld as a weak spot. The image below is an example of a weld cross-section and the weld bead overlap at the bottom is typical of laser welding processes.
Applications
Pasteurization systems
Steam-injected pasteurization systems produce high levels of shock and vibration.
The TCC construction is robust and durable for even these types of applications.
Temperature control is critical for proper elimination of bacteria. Improper pasteurization can result in total loss of product.
Automate measurement uncertainty through the TCC's calibration check feature.
CIP skids
CIP processes involve multiple cycles of hot and cold liquids to ensure adequate cleaning. This thermal shock can cause temperature instruments to drift, raising measurement uncertainty.
*The TCC is resistant to thermal shock due to the construction of the sensing element system.
*The large LED on the housing provides a visual indication of measurement uncertainty.
Cold storage vessels
Condensation seen in cold storage tanks can cause ingress in traditional "head chamber / hockey puck" transmitters.
The one-piece sealed construction of the TCC eliminates moisture ingress.
Temperature control is critical for product quality.
Automate measurement uncertainty through the TCC's calibration check feature.
Tank farms
Every tank has multiple points of measurement, including temperature, level, pressure, conductivity, etc. Each instrument requires wiring and signal processing for production operation.
The TCC is equipped with IO-Link to provide a digital network for cost-effective installation. The dual measurement values from one TCC sensor add redundant measurement without additional cost.
