Littelfuse LLC44B4A Liquid Level Control

The Littelfuse LLC44B4A Liquid Level Control is an electronic monitoring control that supervises liquid level conditions through conductive sensing. Installed inside the equipment control section with sensing probes positioned in the liquid reservoir, it detects changing liquid levels by measuring electrical conductivity and communicates status to connected pumps, alarms, or control circuits within HVAC systems. Signal processing responds to rising or falling liquid conditions, coordinating operating sequences according to measured levels. The liquid control, coordinated equipment response, proper pump operation, monitoring, and consistent overall system performance.
