WE710 Surface Temperature Sensors

Built for Demanding Applications

Surface temperature sensors are a crucial tool for monitoring critical equipment and processes in marine environments. They provide accurate and reliable temperature readings, allowing for proactive maintenance and ensuring optimal performance.

This guide dives deep into surface temperature sensors, exploring their key features, applications, and best practices for accurate temperature measurement.

Key Features of Surface Temperature Sensors:

  • 4-20 mA Output: This industry-standard signal simplifies integration with existing instrumentation and data logging systems. It offers a linear relationship between the output current and the measured temperature, allowing for easy conversion and monitoring.
  • Marine Grade Cable with Strain Relief: The sensor is directly molded onto a marine-grade cable, eliminating potential connection points that could weaken or fail under harsh conditions. Strain relief protects the cable from damage caused by bending or pulling, ensuring long-term reliability.
  • Fully Encapsulated Electronics: The sensor’s electronics are completely sealed within a rugged, marine-grade epoxy shell. This encapsulation safeguards the internal components from moisture, corrosion, and other environmental elements that can compromise functionality.

Applications of Surface Temperature Sensors in Marine Environments:

  • Pipe Temperature Monitoring: Maintaining optimal temperature in pipes carrying fluids is crucial for preventing overheating, pressure build-up, and potential equipment damage. Surface temperature sensors can be strategically placed on pipes to monitor internal fluid temperature without interrupting flow.
  • Solar Panel Temperature: Solar panel efficiency is highly dependent on temperature. By monitoring surface temperature, you can identify potential performance issues caused by excessive heat. This allows for adjustments to maximize energy production and ensure the longevity of your solar panels.
  • Water Tanks: Monitoring water temperature in tanks is essential for various applications, such as ballast control, freshwater storage, and aquaculture. Surface temperature sensors can provide accurate readings, allowing for adjustments to maintain desired water temperature levels.
  • Control Panels: Heat buildup within electrical control panels can lead to malfunctions and equipment failure. Strategically placed surface temperature sensors can monitor control panel temperature, ensuring safe operation and preventing overheating.
  • Battery Monitoring: Maintaining optimal battery temperature is critical for maximizing lifespan and performance. Surface temperature sensors can be used for accurate battery monitoring, allowing for adjustments to cooling systems and preventing overheating.

Beyond the Basics: Ensuring Accurate Temperature Measurement

  • Direct Contact: For accurate readings, ensure the surface temperature sensor is in direct contact with the surface you want to monitor. Any air gaps or insulation can significantly affect the measured temperature.
  • Thermal Compound: Utilize the provided silicone heat transfer compound to improve thermal conductivity between the sensor and the monitored surface. This ensures efficient heat transfer for precise temperature readings.
  • Minimizing External Influences: Keep the sensor clean and free of dirt, grease, or other contaminants. These can act as insulators and alter the measured temperature. Additionally, avoid placing the sensor near heat sources or in direct sunlight, as this can influence the readings.
  • Sensor Selection: Consider the temperature range you need to monitor when selecting a surface temperature sensor. Different sensors have varying operating ranges. Choose a sensor that can handle the expected temperature fluctuations in your application.

Benefits of Utilizing Surface Temperature Sensors:

  • Enhanced System Performance: By monitoring critical equipment and processes, you can identify and address potential issues before they escalate, preventing costly downtime and ensuring optimal system performance.
  • Improved Safety: Proactive temperature monitoring can help prevent accidents and equipment failures caused by overheating. This is particularly crucial in marine environments where unforeseen issues can have serious consequences.
  • Extended Equipment Lifespan: By maintaining ideal operating temperatures, you can significantly extend the lifespan of your valuable equipment and reduce maintenance costs.
  • Data-Driven Decision Making: Continuous temperature monitoring provides valuable data that can be used to optimize processes, improve efficiency, and make informed decisions regarding equipment maintenance and upgrades.


Surface temperature sensors are a versatile and valuable tool for ensuring accurate and reliable temperature monitoring in demanding marine environments. By understanding their features, applications, and best practices for deployment, you can leverage these sensors to enhance system performance, improve safety, extend equipment life, and make data-driven decisions for your marine operations.
