Submersible sensors and instruments deployed in high-temperature liquids face unique challenges:
- Material Degradation: Many common materials used in sensor construction, including plastics and adhesives, can degrade rapidly at elevated temperatures. This can lead to sensor failure and inaccurate readings.
- Electronics Reliability: Electronic components are highly susceptible to heat. Continuous operation at high temperatures can significantly reduce their lifespan and reliability.
- Cable Integrity: Standard cable insulation can soften, melt, or become brittle in hot liquids, compromising signal transmission and potentially leading to short circuits.
To ensure reliable operation in high-temperature liquids, specialized design and construction are essential:
- High-Temperature Materials: Sensor housings, probes, and wetted parts are constructed from materials like stainless steel, titanium, or high-temperature polymers that can withstand prolonged exposure to hot liquids without degradation.
- Specialized Electronics: Heat-Resistant Electronics: The internal electronics, including PCBs and sensors, are designed to operate reliably at elevated temperatures. This may involve using components with extended temperature ratings, specialized potting compounds, and thermal management techniques.
- High-Temperature Cables: Cables are typically constructed with high-temperature tolerant materials like TPE to maintain signal integrity and prevent damage in hot environments.
Applications
- Heated Fuel Tanks: Accurate level and temperature monitoring in fuel tanks ensures efficient operation and prevents safety hazards.
- Food Processing: Submersible sensors play a vital role in maintaining precise temperatures during cooking, sterilization, and cleaning processes, ensuring food safety and quality.
- Heated Water Tanks: Monitoring temperature and level in hot water tanks is crucial for optimal performance and energy efficiency in industrial and commercial settings.
- Industrial Processes: High-temperature submersible sensors are used in various industrial processes involving hot liquids, such as chemical manufacturing, oil and gas production, and power generation.
