Liquid Level Controller
The Model 4042 Liquid Level Controller provides precise monitoring and control for water levels up to 34.6 feet. Its robust design ensures reliable operation across diverse industrial environments. Featuring 4 SPDT contacts, the unit offers versatile control capabilities for various applications, supporting both resistive and inductive loads up to 10A at 240VAC and 4A at 120VAC respectively. User-adjustable trip levels enhance operational flexibility, allowing for tailored system responses. With an input voltage of 120VAC and a maximum power consumption of 6W, it integrates efficiently into existing setups. The controller maintains accuracy with a repeat accuracy of ± 1% of scaled maximum under fixed conditions. Its 3-1/2 digit LCD provides clear display of levels, supporting effective process management. Engineered for consistent performance, it operates reliably from +14° to +122° F and tolerates 0-97% humidity without condensation. This ensures dependable functionality in challenging conditions.
