Omron 61-F-11 Relay unit.

Omron 61-F-11 Floatless Level Switch – Reliable Liquid Level Control Relay

Product Description

The Omron 61-F-11 is the industry-standard "floatless" level switch, designed for automatic water supply and drainage control. Unlike mechanical float switches that can stick or fail, this solid-state relay uses conductive probes to detect liquid levels, making it the most reliable solution for tanks, reservoirs, and process vats. Built with Omron’s renowned Japanese-engineered precision, the 61-F-11 ensures long-term operational stability, preventing dry-running of pumps and unnecessary overflows.

Technical Specifications

• Brand: Omron

• Model: 61-F-11

• Product Type: Floatless Level Controller (Automatic Water Supply/Drainage)

• Mounting: Panel/DIN Rail mount

• Supply Voltage: 110/220VAC (Commonly used 230V configuration)

• Operation: Conductive level detection (requires electrodes/probes)

• Application: Water, wastewater, conductive chemicals, and liquid storage

Key Features

• Floatless Reliability: By eliminating moving parts (floats) inside the tank, this unit is virtually maintenance-free and immune to the mechanical sticking issues common in dirty or turbulent liquid environments.

• Versatile Logic: Specifically engineered for automatic water supply (pumping when low) or drainage (pumping when high), providing an all-in-one solution for tank level automation.

• Omron Quality: As an authorized dealer, Jai Govinda Trade Links provides genuine Omron units that guarantee fast response times, consistent accuracy, and protection against electrical noise.

• Easy Integration: Compact design for seamless panel mounting and straightforward wiring with standard industrial probes.

Common Applications

• Water & Wastewater Management: Automates filling and emptying cycles for domestic and industrial water tanks, preventing pump burnouts.

• Boiler & Steam Systems: Reliable level sensing for condensate tanks and feed-water monitoring.

• Chemical Processing: Monitors levels in chemical holding tanks (conductive liquids only) where precise, reliable switching is a safety requirement.

• Industrial Cooling: Essential for cooling tower level control and automated makeup water systems.
