What is the pressure tank supervisory signal range?

The supervisory signal range for a pressure tank is typically set at plus or minus 10 PSI. This range is essential for maintaining system integrity and ensuring that the pressure levels are monitored effectively.

When the pressure within the tank fluctuates outside this range, the supervisory system can indicate an issue that may require attention, such as a leak or a malfunctioning component. Adhering to this standard range helps to prevent false alarms while providing a reliable indication of the pressure status in the system, which is vital for the safety and functionality of equipment relying on consistent pressure levels.

Choosing a wider range, like plus or minus 15 or 20 PSI, could lead to delayed responses to legitimate issues, while a narrower range of plus or minus 5 PSI may result in unnecessary triggers of alarms due to minor fluctuations that do not impact performance significantly. Therefore, the range of plus or minus 10 PSI is both practical and functional for supervisory signaling in pressure tank applications.
