Sensores

Important Points!
• Product must be maintained and installed in strict accordance with the National Electrical Codes, Gems technical brochure, instruction bulletin, and any applicable electrical code in the country in which the product is installed. Failure to observe this warning could result in serious injuries or damages. • For hazardous area applications involving such things as (but notlimited to) ignitable mixtures, combustible dust and flammable materials, use an appropriate intrinsically safe interface device. • Warning: To prevent ignition of flammable or combustible atmospheres, disconnect power before servicing. • The pressure and temperature limitations shown on the individual catalog pages and drawings for the specified level sensors must not be exceeded. These pressuresand temperatures take into consideration possible system surge pressures/ temperatures and their frequencies. • Selection of materials for compatibility with the media is critical to the life and operation of GEMS level sensors. Take care in the proper selection of materials of construction, particularly wetted materials. • Electrical entries and mounting points in an enclosed tank may requireliquid/vapor sealing. • Physical damage sustained by the product may render it unserviceable.

Note
XM-800 Series includes models XM-800, XMP-800, XM-850, XM-820 XT-800 Series includes models XT-800, XTP-800,XT-850, XT-820

Designed for continuous liquid level sensing, GEMS transmitters are considered "components".

Operating Principle
The XM/XT-800 utilizes reed switch/magnet technology. A magnet-equipped float rises or lowers with corresponding liquid level. The magnetic field generated from the float
