Electrode Level Switch 1mm

A level switch is an essential device used to detect and control the water level in a reservoir, tank, basement, or other space. Its primary purpose is to automatically switch a pump, valve, or other mechanism on or off based on preset water levels. This prevents flooding, pumps running dry, or ensures that a specific water level is maintained.

The SOS PUMP® Electrode Level Switch 1mm is a specific type of level switch that operates based on conductivity. As soon as water touches the electrodes, an electrical circuit is closed, generating a signal. This signal is then used to control connected equipment, such as a submersible pump. What makes this model unique is its extremely low cut-in height of just 1mm, making it ideal for situations where almost all of the water needs to be drained.

This technology is exceptionally reliable and durable because, unlike traditional float switches, there are no moving parts to seize or wear out. This makes the electrode level switch a low-maintenance and precise solution for automatic water level control in various applications, from residential to industrial processes.

Choosing the right level switch is crucial for optimal operation of your pump system. Several factors must be considered to ensure your level switch perfectly meets your needs.

First, the type of fluid is crucial. The SOS PUMP® Electrode Level Switch 1mm is designed for clean water. For fluids containing many solids, chemicals, or high viscosity, other types of level switches, such as float switches or ultrasonic sensors, may be more suitable. Always check the switch's specifications to ensure it is compatible with the fluid you intend to monitor.

The required switching height is another important consideration. Do you want a pump to switch on at a minimum water level, as with the SOS PUMP® Electrode Level Switch 1mm, which operates from 1 mm? Or do you need a larger margin? Some applications require precise water level control, while others are less critical. The electrode level switch with its three rods offers very precise control over both the switch-on and switch-off points.

Also consider the environment in which the level switch will be used. Is there limited space, such as in a small basement or shaft? The compact size of the electrode level switch makes it ideal for such situations. Temperature, pressure, and the presence of corrosive substances can also influence your choice. Ensure that the switch's materials are resistant to the environmental conditions.

Finally, consider installation and wiring. Should the switch directly control the pump, or should it transmit a signal to a control system? The SOS PUMP® Electrode Level Switch 1mm is designed for direct control of a submersible pump, which simplifies installation. Pay attention to the electrical specifications, such as voltage and amperage, to ensure compatibility with your pump.

Correct installation and adjustment of your level switch is essential for reliable operation. Our specialists are happy to share some practical tips to get the most out of your SOS PUMP® Electrode Level Switch 1mm.

When installing the electrode level switch, the positioning of the rods is crucial. The white rod marks the lowest point and serves as a reference for the ground level. The green rod determines the pump's start level, and the red rod indicates the stop level. Ensure these rods are positioned at the desired heights relative to the surface where the water collects. Even a slight deviation can result in unwanted activation or deactivation of the pump. Use the supplied mounting hardware to mount the switch securely and stably.

Although the electrode level switch requires little maintenance, it is advisable to periodically check the electrodes for contamination. Limescale or other deposits can affect conductivity and reduce the switch's accuracy. Gently clean the electrodes with a soft brush and water if necessary. Always ensure the power is turned off before performing any maintenance.

After installation, always check the level switch's operation by manually adding and draining water. This allows you to verify that the pump switches on and off at the correct times. If the pump doesn't respond as expected, first check the electrical connections and the positioning of the rods. Ensure the wiring is correctly connected according to the diagram and that there are no short circuits.

A common problem is that the pump continues to run or fails to start. This can often be resolved by slightly adjusting the position of the electrodes. Sometimes, too low a conductivity of the water, for example, with very pure rainwater, can also affect operation. However, in most household situations, this isn't a problem. By following these tips, you can ensure long-term and reliable operation of your level switch.

Is the SOS PUMP® Electrode Level Switch 1mm suitable for dirty water? No, this specific level switch is primarily designed for clean water. Solid particles in dirty water can contaminate the electrodes and affect their reliability. For dirty water, we recommend a float switch.

Can I adjust the switching heights myself? Yes, the switching heights are determined by the relative positions of the three bars (white, green, red). By mounting the switch at the correct height and positioning the bars, you can precisely adjust the on and off heights.

What happens if the power goes out? During a power outage, the level switch will not function and will not control the pump. Once power is restored, the switch will resume normal operation based on the current water level.

Is the installation complicated? Installation is relatively simple and requires basic electrical knowledge. The switch comes with clear instructions. If in doubt, we always recommend consulting a qualified electrician.

What's the advantage over a float switch? The biggest advantage is its precision and the ability to switch even at extremely low water levels (1 mm). Furthermore, an electrode level switch has no moving parts, which improves reliability and longevity, especially in confined spaces where a float could get stuck.
