Controller for conductive liquid level sensing
The Omron 61F-GP-N2-AC120 is a High/Low Level controller from the 61F series, designed to detect conductive liquid levels via electrode probes. It operates on a 120 VAC supply and uses a plug-in 8-pin octal base for termination. Sensitivity is adjustable from 0 to 4 kOhm, covering most conductive liquids (water, dilute chemicals). The socketable mounting means the controller body can be swapped without rewiring the base — a time-saver on a line-down call. Rated for an ambient temperature range of -10°C to 55°C, so it's fine inside a non-condensing control cabinet near a tank. No washdown rating here — keep it dry.
