4. Structure and Composition

4.1 Typical Components

• Temperature-sensing Element: Pt100 platinum resistance thermometer with ceramic or thin-film packaging
• Protective Tube: 316 stainless steel material, with a common outer diameter of 6mm
• Terminal Block: Four terminals (I+, I-, V+, V-) arranged inside the junction box
• Connecting Wire: Insulated wire with customizable length
• Mounting Accessories: Threaded connectors, compression glands, waterproof sealing parts and other matching components

4.2 Structural Characteristics

• The temperature measuring end adopts a spring compression structure, which ensures tight and stable contact with the measured object for accurate temperature collection.
• Armored structure effectively protects the internal temperature-sensing element, significantly enhancing the overall mechanical strength and shock resistance of the sensor.

5. Application Fields

6. Installation Requirements

6.1 Installation Position Selection

• Select positions with representative temperature and humidity changes to ensure authentic and effective measurement data.
• Keep away from strong magnetic field interference areas and positions with frequent mechanical vibration.
• Avoid temperature dead zones to guarantee the accuracy of temperature detection.

6.2 Installation Methods

• Support threaded connection installation (specifications include M27×2, NPT1/4, etc.).
• Vertical installation is recommended to prevent structural deformation under high-temperature conditions.
• For positions with water flow impact, install the sensor at a 30°-45° inclined angle.
• Auxiliary support brackets are required for installation in special harsh environments for protection.

6.3 Insertion Depth Requirements

• For soil temperature measurement, the insertion depth shall be 8 to 10 times the diameter of the protective tube.
• Ensure sufficient insertion depth during industrial pipeline installation to avoid inaccurate measurement caused by insufficient contact.

6.4 Electrical Connection Specifications

• Arrange the outlet hole of the junction box downward to prevent moisture and water vapor from entering the interior.
• Complete wiring in strict accordance with the official manual to ensure correct and reliable electrical connection.

6.5 Protection Requirements

• Pay attention to daily waterproof and dustproof protection of the sensor.
• Fully consider the thermal deformation of the protective tube when working in long-term high-temperature environments.

7. Maintenance and Upkeep

7.1 Regular Inspection

• Check the connecting wires regularly for looseness, damage or aging.
• Verify that the protective tube is free from deformation, corrosion and abrasion.
• Inspect the sealing performance of the junction box to ensure good tightness.

7.2 Cleaning and Maintenance

• Clean the sensor probe with a soft damp cloth regularly.
• Do not use corrosive chemical cleaners to avoid damaging the probe surface and internal components.
• Keep the probe surface clean and free of oil, dust and other attachments.

7.3 Calibration Cycle

• Annual professional calibration and adjustment is recommended to maintain measurement accuracy.
• Contact the manufacturer for official standardized calibration services.

7.4 Service Life

• The service life of the sensor is 5-10 years under standard normal working conditions.
• The service life will be shortened accordingly when operating in high-temperature, corrosive and other harsh environments.

7.5 Fault Troubleshooting

• Abnormal Resistance Value: Check whether the internal temperature-sensing element is damaged or failed.
• Decreased Insulation Resistance: Inspect the sensor for water ingress, moisture or surface contamination.
• Measurement Drift: Perform professional recalibration to restore detection accuracy.
