1. Product Description
The CERTEON PP Side Mount Float Switch is a horizontal plastic liquid level sensor designed for precise point-level detection of liquids within tanks and containers. Its operation relies on a magnetic reed switch mechanism integrated into the float assembly. As the liquid level changes, the float moves, causing the internal reed contact to open or close the electrical circuit.
Constructed from durable polypropylene (PP), this float switch offers excellent chemical resistance, making it suitable for a wide range of applications including water treatment, industrial process control, and general liquid level monitoring.

3. Package Contents
The product package typically includes:
- Float switch unit
- Sealing gasket
Note: Additional accessories may be included depending on the specific order.
4. Installation
4.1. Preparation
- Verify that the selected float switch model matches your system's voltage and power requirements.
- Ensure the liquid in your application is chemically compatible with polypropylene material to prevent degradation.
- Check that the mounting port on your tank or container matches the M12 x 1.25 thread specification of the float switch.
4.2. Mounting
- Install the float switch horizontally on the tank wall using its threaded connection.
- Use a suitable gasket or sealing tape to ensure a proper seal and prevent any leakage.
- Orient the float according to your desired normally open (NO) or normally closed (NC) configuration for the circuit.
5. Electrical Connection
- Connect the two lead wires of the float switch in series with your control circuit.
- Ensure that the electrical load does not exceed the specified maximum voltage, current, and power ratings of the float switch to prevent damage or hazards.
- Always disconnect the power supply before performing any wiring or maintenance.
Why add relays? Since the switch contact capacity inside the float ball is small, float switches cannot directly control high-power devices such as water pumps, solenoid valves, or AC contactors. A small relay (e.g., HH52P/HH54P) is required to operate the float switch with such loads. If the load involves motors or heavy inductive loads, it is especially important to connect it to a relay to prevent misoperation due to current fluctuations.
6. Operation and Data Reading
- The float switch operates by changing the state of its internal reed switch when the liquid level reaches the float's position.
- The output signal from the float switch can be used to control various devices such as relays, alarms, or directly as digital inputs for Programmable Logic Controllers (PLCs).
- During commissioning, verify the switching function by gradually filling or draining the tank to observe the float switch's response.
7. Storage and Maintenance
7.1. Storage
- Store the float switch in a dry and well-ventilated environment.
- Keep it away from direct sunlight.
- Avoid storing near strong acids, alkalis, or solvents when not in use, as these can degrade the polypropylene material.
7.2. Daily Maintenance
- Regularly remove dirt or debris from the guide rod and float. The cleaning frequency depends on the medium's cleanliness.
- Check if the retaining ring buckle is loose and secure it if necessary.
- Do not attempt to disassemble the sealed reed switch housing.
- If a malfunction occurs, replace the entire unit. Internal components are not user-serviceable.
8. Precautions and Safety Warnings
8.1. General Precautions
- Do not exceed the specified maximum voltage, current, or power rating to prevent damage.
- Avoid using the switch in liquids that may chemically degrade polypropylene.
- Do not operate the device in environments exceeding the defined temperature range.
- Avoid strong vibration or mechanical impact during operation.
- Ensure proper insulation of all wiring connections.
- This device is not suitable for explosive atmospheres unless additional certified protection measures are explicitly implemented.
8.2. Safety Warnings (EU Market Reference)
WARNING!
- Risk of electric shock if used with high voltage circuits.
- Disconnect power supply before any installation or maintenance procedures.
- Do not exceed rated electrical limits to prevent overheating or fire hazards.
- Ensure proper grounding of all associated equipment.
- 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.
9. User Tips
- For optimal performance and longevity, ensure the float switch is installed correctly and securely, paying close attention to sealing to prevent leaks.
- Regularly check for and remove any buildup on the float and guide rod, especially in environments with particulate matter, to maintain accurate level detection.
- When connecting to pumps or other high-power devices, always use an appropriate relay to protect the float switch from excessive current and voltage.
- Consider the specific liquid's properties (e.g., viscosity, chemical composition) to ensure compatibility with the polypropylene material and reliable operation.
10. Troubleshooting
10.1. Common Issues and Solutions
| Problem | Possible Cause | Solution |
|---|---|---|
| Switch not activating/deactivating | Incorrect wiring; debris on float; float stuck; incorrect orientation; load exceeding capacity. | Check wiring diagram; clean float and guide rod; ensure proper orientation (NO/NC); use a relay for high loads. |
| Leakage at mounting point | Improper sealing; damaged gasket; loose connection. | Re-install with new gasket/sealing tape; tighten connection appropriately. |
| Inconsistent readings | Debris interfering with float movement; excessive vibration; liquid properties incompatible. | Clean float; reduce vibration if possible; verify liquid compatibility. |
| Switch failure | Electrical overload; chemical degradation; physical damage. | Ensure proper electrical limits are observed; verify liquid compatibility; replace unit if damaged. |
