Liquid Level Controller
The Model 403 Liquid Level Controller provides precise fluid management for industrial applications. Its robust design, featuring a 20 gauge Steel case, ensures durability in demanding environments. Operators benefit from selectable lead/lag or automatic alternation, optimizing pump wear and system efficiency. Four distinct sensing levels allow for granular control over liquid volumes. Dual non-resettable run-time meters track operational hours up to 99,999.9, providing critical data for maintenance scheduling and performance analysis. With a 10A contact rating at 240VAC resistive and 2500V transient protection, this controller offers reliable performance and system longevity. Its 105-130VAC input voltage ensures broad compatibility. The unit's internal power-fail contact and removable terminal strip further enhance its utility and ease of integration, making it a dependable solution for critical level control tasks.
