Industries with strict hygiene requirements, such as pharmaceuticals, life science and food, ZHICE provide precise and efficient solutions to safeguard quality and stay compliance. Product safety, compliance and data integrity In food and pharmaceutical production, strict safety guidelines and quality standards must be followed and the production process must be consistent and reliable. This guarantees the safety of food and pharmaceuticals and ensures that the final product quality is as high as possible, which is essential to maintaining the safety of the end consumer. Sterilization is a critical step in the manufacturing process that kills any bacteria and helps ensure that drugs, packaging, utensils, clothing, etc. are safe to use. Temperature Distribution and Heat Penetration The most common method of sterilization is heat. Temperature distribution refers to how evenly heat is spread throughout the sterilization chamber/autoclave. Proper heat distribution ensures that every part of the chamber reaches the required temperature for sterilization. Uneven heat distribution, can result in certain areas not achieving the necessary conditions (cold spot), leading to incomplete sterilization. Achieving uniform temperature throughout the sterilizer is essential for effective sterilization. Another parameters that we pay attention to is heat penetration. It indicates how effectively heat moves through the product or materials being sterilized. Thus the sensor/logger is placed inside the package to ensure that not only the surface but also the innermost parts of the product reach the required temperature for a sufficient period to achieve sterilization. A better way to validate sterilization process Many of the world’s leading pharmaceutical, life sciences and food companies rely on ZHICE temperature validation system, designed to help users stay compliance according to industry regulations, such as GMP and FDA. Our solutions have flexible configurations and can be selected based on the sterilizer situation and laboratory capabilities. ZHICE-ELEC not only provide temperature sensors, reading devices and validation software, but also pre- and post-calibration temperature field.

Introductions RTDs use a high-precision resistor, typically made of platinum, whose resistance increases with temperature. They offer high accuracy and stability thus are commonly used in industrial applications and typically come in 2, 3, or 4-wire configurations. Thermocouples consist of a junction between two different metal alloys, generating a voltage that varies with temperature. They are versatile, cost-effective, and can measure a wide range of temperatures. Common types include J, K, T, and N, each defined by the metals used and their specific temperature range and sensitivity. NTC thermistors are resistors that decrease in resistance as temperature increases. They are highly sensitive and respond quickly to temperature changes, making them suitable for applications requiring rapid detection of temperature variations.

The widely adopted Pt100 standard has a resistance of 100.0 Ohms at 0°C and changes by 38.50 Ohms from 0 to 100°C. Platinum resistors provide highly stable and accurate temperature measurements. RTDs are usually 2-wire devices but can be extended to 3 or 4 wires for enhanced accuracy. Thermocouples: Thermocouples consist of a junction between two different alloys and a two-wire extension. The EMF generated between the hot junction and a reference junction creates a stable and repeatable temperature measurement. Various thermocouple types (e.g., J, K, T, N) are defined by the alloys used, each displaying distinct EMF characteristics. RTD’s are, generally: • More expensive • More accurate • Highly stable (if used carefully) • Capable of better resolution • Restricted in their range of temperature • Stem, not tip sensitive • Rarely available in small diameters (below 3mm) Thermocouples are, generally: • Relatively inexpensive • More rugged • Less accurate • More prone to drift • More sensitive • Tip sensing • Available in smaller diameters • Available with a wider temperature range • More versatile Conclusion Each sensor type has its strengths and is chosen based on the specific requirements of the application, such as accuracy, temperature range, response time, and cost.
