Catalogue - Level Sensors - Continuous - GEMS SENSORS & CONTROLS



		GEMS Continuous Electrical Output Transmitters Provide Direct Liquid Measurement ► Lengths to 18 feet (5.5 m) ► Alloys or Engineered Plastic Wetted Parts ► Analog Output Completely electronic, Gems Liquid Level Transmitters provide reliable and durable remote tank gauging. A wide variety of material combinations provide compatibility for most liquid media. Gems XM- & XT-800 Series provide solutions for most small to mid-size tanks in both process and OEM applications; for deeper tanks (to 18 feet) look to Gems 36000 and 66000 Series. Gems experienced engineering and sales staff can provide customized solutions for applications not satisfied by the standard transmitters shown in this catalog. Do not hesitate to contact Gems if you require a configuration not shown here. Single Probe or Complete Systems As a component, Gems transmitters provide the output options compatible with most programmable controllers and other digital receivers. Combined with Gems Digital Receivers you can create a complete tank gauging system. Typical Applications Consider GEMS' versatile transmitters for all your continuous liquid level monitoring needs — water, diesel, lube oils and fuels, as well as various chemical and petrochemical liquids. Here are just a few areas where GEMS' transmitters are used: • Utilities • Beverage Industry • Medical • Pharmaceuticals • OHV • Food Processing • Wineries • Printing • HVAC • Semiconductor Operating Principle Gems voltage divider design uses a staggered series of reed switches. As the float moves with the liquid level, the magnets in the float close these reed switches in a "2-3-2 at-a-time" sequence. With every movement of the float, either one additional switch closes or one drops off. TRANSMITTER HOUSING PERMANENT MAGNET FLOAT

What does this mean to you? Ensures better accuracy — if one switch was to fail, the signal would be affected only at that point.					GEMS Transmitters monitor water, diesel or lube oils, chemicals and petrochemicals in industries such as pharmaceuticals, municipalities, breweries, textiles, automotive, pulp and paper and others.
