Product overview

Core functionalities

Applicable scenarios

Unique advantages

  • Precise Temperature Monitoring: Designed to accurately measure and regulate water temperature in generator systems and industrial equipment, ensuring optimal performance and preventing overheating.
  • Durability & Reliability: Built with brass construction for corrosion resistance and superior thermal conductivity, maintaining accuracy in harsh environments.

Key features

  • 1. Corrosion-Resistant Brass Construction

  • With a corrosion-resistant brass body, you can ensure long-lasting durability in harsh industrial or automotive environments. Unlike plastic-based sensors, brass withstands chemical exposure and temperature fluctuations, maintaining structural integrity over time.

  • 2. Threaded Cylindrical Design for Secure Installation

  • With a threaded cylindrical body and extendable probe, you can achieve precise temperature measurement in pipes or conduits. The threaded end simplifies installation compared to models requiring adhesives or clamps.

  • 3. High-Precision Temperature Monitoring

  • With a measurement range up to 88°C ±3°C, you can reliably track critical thermal conditions in generators or engines. This accuracy outperforms standard sensors with broader error margins, ensuring optimal system performance.

  • 4. Industrial-Grade Compatibility & Versatility

  • Designed for industrial and automotive applications, you can integrate these sensors into generator systems or heavy machinery for continuous temperature monitoring. Their robust build suits scenarios requiring 24/7 operation, unlike consumer-grade sensors.

  • 5. Voltage Range Flexibility

  • With a 8–24V operational voltage range, you can adapt to diverse power systems without additional converters. This flexibility exceeds single-voltage models, simplifying integration into existing setups.

  • Notes:

    • The product’s brass material and threaded design emphasize durability and ease of installation compared to plastic or non-threaded alternatives.

Supplier's note

  1. Technical Breakthroughs:

    • Brass Construction: Outperforms plastic sensors in corrosion resistance (tested in saltwater environments).
    • ±1.5°C Accuracy (Pro): 50% better precision than industry standards for critical thermal control.
    • 36V Compatibility (Pro): 50% higher voltage tolerance than base models, enabling use in heavy machinery.
  2. Version Selection Guide:

    • Base Model: Ideal for standard automotive systems (e.g., car radiators) needing cost-effective replacements.
    • Advanced Model: Best for industrial pumps or HVAC systems requiring longer probes (70mm) and wider voltage support.
    • Pro Model: Engineers handling high-temperature applications (e.g., boiler systems) benefit from its 150°C tolerance and ±1.5°C precision.

With the Pro’s triple-certified chemical resistance, you can safely monitor corrosive fluids. Pair its nickel probe with high-temperature insulation for unmatched reliability in extreme conditions.
