Description
The Warrick-Gems Sensors & Controls 26NMB1A0A is a precision plug-in liquid level control module engineered for dependable low water cutoff protection in boiler and hydronic heating systems. Designed for straightforward installation into a standard 11-pin octal socket, this module delivers reliable liquid level sensing without the need for a dedicated enclosure — making it an ideal choice for panel-mounted or integrated control applications.
How It Works
Operating in Direct Acting mode, the 26NMB1A0A responds immediately to changes in liquid level, providing fast and accurate cutoff control. The module uses a 10,000-ohm sensing resistance to detect the presence or absence of water, triggering the onboard SPDT relay to protect boilers and heating equipment from dangerous low-water conditions.
