Installation Steps
Correct installation is the prerequisite for ensuring the measurement accuracy of the CLD134. Please operate according to the following steps:
- Confirm that the installation location has no strong vibration or corrosive gases, and reserve sufficient maintenance space.
- Install the conductivity cell on the pipeline or immersion bracket, ensuring the electrode is fully immersed and free of bubbles.
- Connect the temperature sensor (Pt1000) to the corresponding terminal, paying attention to polarity.
- Connect the power supply and output signal lines according to the wiring diagram, and tighten the cable gland to achieve IP67 protection.
- After power-on, enter the menu and set the conductivity cell constant, temperature compensation mode, and output range.
Model Comparison
To meet the needs of different working conditions, the CLD134 provides multiple configuration options. The table below compares the differences among common models.
| Model | Conductivity cell constant | Output | Typical application |
|---|---|---|---|
| CLD134-01 | 0.01 cm⁻¹ | 4-20 mA | Ultrapure water |

| CLD134-30 | 10 cm⁻¹ | Modbus RTU | High-concentration acid-base |
Maintenance and Calibration
Regular maintenance can extend the service life of the CLD134 and maintain measurement accuracy. It is recommended to calibrate every 3-6 months.
- Use standard conductivity solutions for calibration, and rinse the electrode with deionized water before calibration.
- Check whether there is dirt or scaling on the electrode surface, and clean it with a soft cloth and diluted acid if necessary.
- Confirm that the cable seal is not damaged to prevent moisture from entering the transmitter.
- Record calibration data for traceability and trend analysis.
Frequently Asked Questions
1. What should I do if the measured value fluctuates greatly?
Check whether the electrode is fully immersed and whether there are bubbles, and confirm that the temperature compensation setting is correct. If it still fluctuates, try changing the conductivity cell constant or recalibrating.
2. How do I troubleshoot abnormal output signals?
First confirm whether the power supply voltage is within the rated range, then check whether the output load matches. For 4-20 mA output, ensure that the loop resistance does not exceed the allowable value.
3. What if the manual cannot be opened after download?
