If the long probe connection in a liquid level control system breaks, what happens?

When the long probe connection in a liquid level control system breaks, the system typically reverts back to single probe operation. In a dual-probe system, one probe usually serves as a high-level sensor while the other acts as a low-level sensor, allowing for more precise control of liquid levels.

If the long probe connection, which is often responsible for detecting the high liquid level, fails, the control system will lose its ability to monitor that specific high point accurately. As a result, the system will default to using a single probe for level detection. This fallback is necessary to maintain some level of operation, even if it means the control system is less sophisticated in its ability to manage liquid levels. The single probe can still signal when the liquid reaches a certain low point, but any added safety features or controls related to the high level may be compromised.

This response helps maintain system functionality, but it does introduce a risk of overfilling if the single probe is not capable of adequately addressing the liquid levels that were previously monitored by the long probe.
