Gems Sensors & Controls has introduced a new line of compact low-water cutoff devices to provide critical protection for boilers and steam generators. The new LWC-700/720/800 Series offer a variety of configurations and functions for application in most water feed vessels. They feature redundant switches within the liquid level sensors, and electronic controllers to deactivate systems before a water supply problem can damage or create a critical situation in boiler or steam generation equipment. They meet CSD1 requirements and are UL Recognized per UL-353 for “Limit Control.”
The company says the LWC-700 offers Gems’ most compact internally-mounted package, and is configurable from the factory in customer-specified length and low-water actuation level switch positioning. The LWC-720 Series includes the same low-water cutoff function and adds pump up control for more sophisticated and convenient water control automation. For tanks with limited internal space, the LWC-800 Series utilizes an external bottle for the liquid level sensor and provides the same sensing and controlling function as the LWC-700 Series.
The controller box for each of the series may be mounted directly on the sensor unit head, or mounted up to 2 ft away via an electrical conduit configuration offered as one of the options.
