Temperature Sensors for Cold Chain and Continuous Data Logging & Monitoring | Application SPotlight


cold_chain_iconFood and pharmaceutical products are required to be kept under controlled temperature (often around 0°C) to ensure their safety and quality. A successful cold chain ensures temperature-sensitive products are kept within optimal temperature ranges and maintain the desired states from start to finish. Failure to keep these products cold will render them unusable, which leads to product waste and financial loss. Suppliers of cold chain products are required to keep continuous track of temperature and other parameters that can compromise the integrity of their products.


How do we help?

cold-chain-how_we_helpAmphenol Advanced Sensors carries an extensive line of thermistors, RTD components and finished probe assemblies that meet the broad temperature range requirements for today’s cold chain market. Amphenol Advanced Sensors also offers the ability to meet the customer’s custom package solution requirements, in addition to assemblies that are suitable to withstand harsh surroundings. These thermistors and RTDs can be used in all temperature measurement and control applications with the added assurance of long-term stability and reliability. Our RTDs (temperature range -196°C to 600°C) and NTC Type P (temperature range -80°C to 300°C) are designed for rapid response while maintaining superior accuracy even at extreme low temperatures. We can incorporate these NTC thermistors and RTDs into customer specific designs, providing a robust construction and ensuring long life in harsh clinical environments.


Custom Packaging - Makes us the right choice

cold-chain-custom_packagingWhat sets Amphenol Advanced Sensors apart is our ability to offer custom packaged assemblies. For cold chain applications, finding a solution that meets the required temperature range with a packaging assembly that also fits your needs can be an arduous task, but Amphenol Advanced Sensors prides itself in our ability to customize a unique packaging assembly for each customer. Our attention to thermodynamic properties in the assembly design is critical for matching a customer’s measurement protocol. Whether providing NTC thermistors, RTDs, sub-assemblies, or fully-completed devices, our team is ready to partner with you.


Application Examples:

COVID-19 Vaccine Refrigerated Container Data Logger Temperature Probes

  • The container serves as an incubator or refrigerator, maintaining the required temperature of its vital contents.
  • Temperature probes provide a precise temperature profile to the data logger, verifying a successful transportation of vaccines.


Food Storage and Warehousing Temperature Probes

  • Food products require storage at fixed control temperatures to ensure integrity and safety.
  • Temperature probes ensure this critical parameter is maintained at defined specifications and regulatory guidelines, whether in an individual refrigeration unit or by temperature mapping an entire warehouse.
