3. Setup and Installation

3.1. Preparation

  • Verify that the selected sensor type (e.g., Pt100, K-type) matches the temperature controller input type.
  • Ensure that the process connection thread M12×1 matches the installation port.
  • Confirm probe length and cable length before installation.

3.2. Installation

  1. Install the probe into the threaded process port using the supplied nut and sealing ring.
  2. Tighten securely to prevent leakage.
  3. Avoid excessive torque that may damage the thread or sealing components.

4. Operating Instructions

4.1. Electrical Connection

  • For Pt100: Connect according to the 3-wire configuration of the controller input.
  • For K-type or E-type thermocouples: Connect the 2-wire output to the corresponding thermocouple input terminals.
  • Ensure correct polarity for thermocouples.
Temperature Transmitter Wiring Diagram

Wiring Options
Figure 9: Wiring options: Default (U-type terminals), Customizable (pin terminals), Customizable (aviation plug connector). Pt100 uses 3-core shielded wire; K/E types use 2-core shielded wire. Ensure sensor type matches instrument input type.

4.2. Operation

  1. Power on the temperature controller.
  2. Allow sufficient stabilization time after installation.
  3. The controller will display the measured temperature value.

4.3. Data Reading

Read the temperature value directly from the connected temperature controller or monitoring system. Ensure the measurement range of the controller matches the sensor specification.

5. Storage and Maintenance

5.1. Storage

  • Store in a dry, ventilated environment with ambient temperature between -20°C and +60°C.
  • Avoid exposure to moisture or corrosive gases during storage.

5.2. Maintenance

  • Clean the probe surface with a soft cloth. Do not use abrasive materials.
  • Periodically inspect the cable insulation and thread sealing condition. Replace if damage is observed.

6. Troubleshooting

  • Incorrect Temperature Readings: Ensure the sensor type matches the controller input type. Check wiring for correct polarity and secure connections. Verify the sensor is within its specified temperature range.
  • No Reading: Check all electrical connections. Ensure the controller is powered on and configured correctly for the sensor type. Inspect the cable for any visible damage.
  • Leakage at Connection: Ensure the probe is securely tightened with the supplied nut and sealing ring. Avoid excessive torque during installation.
  • Sensor Damage: Avoid mechanical shock, bending, or pulling on the cable. Do not exceed specified temperature limits.

7. Safety and Precautions

7.1. General Precautions

  • Do not exceed the specified temperature range of the selected sensor type.
  • For environments above 250°C, use a stainless steel metal sheath to prevent cable damage or insulation failure.
  • Ensure proper grounding of shielded cable to minimize electrical interference.
  • Avoid mechanical shock, bending, or pulling on the cable during installation.
  • This product is not designed for use in explosive atmospheres unless additional certified protection measures are applied.
  • Keep away from corrosive chemicals unless corrosion-resistant material is specified.

7.2. Warning Information (EU Market Reference)

WARNING!

  • Risk of high temperature: The probe may become extremely hot during operation. Allow sufficient cooling time before handling.
  • Incorrect wiring: May cause measurement errors or damage to control equipment.
  • Do not use beyond specified temperature limits.
  • Ensure proper installation to prevent leakage in liquid measurement applications.
  • Keep out of reach of children.
  • Proper disposal: Follow WEEE directives for electronic waste.

Note: The above warning information is for reference only. Final warning language must comply with the official language requirements of the destination EU country.
