LEVEL SENSORS Switches Industry’s largest selection of electrooptic liquid level sensors is right here at Gems. Compact design for a small footprint anywhere space is at a premium. Solid-state switching and no moving parts ensures dependability over long service life. Available in a vast range of sizes, mountings and materials, Gems offers the broadest selection of float-type level switches anywhere. Using a proven reed switch design, float type switches deliver long, trouble-free service with precise repeatability. They are available in both single point and multi-point configurations....

LEVEL SENSORS Switches/Transmitters Gems ultrasonic switches and transmitters are ideal for applications requiring solid-state level measurement such as those with ultrapure, dirty, coating, scaling or corrosive-type liquids. Available in contact and non-contact single point, or multi-point versions. Up to four actuation levels or continuous measurement to 26 feet (8 m). Also available for small tanks less than 4 ft. (1.2 m). Made of polypropylene, PVDF, PFA. The ExOsense™ sensor is a break-through in liquid sensor technology. The unique, patented piezo-resonant transducer and...

FLOW SENSORS Sensors/Indicators Paddle Wheel Section F RotorFlow®: These highly visible, paddle wheel designs offer accurate visual indication, flow rate sensing and switching. The visual indication is combined with a choice of either pulsed DC output 0-10V DC analog or adjustable 1 Amp switched output. Available with brass, stainless steel or hydrolytically-stable polypropylene housings. Line sizes: 1/4˝ to 1˝ (.64 to 2.5 cm). Adjustable settings: 0.1 to 60 GPM (.38 to 227 l/m). Proven piston switch technology delivers high repeatability and precise calibration for liquids or gases. Fixed...

PRESSURE SENSORS Transducers Sputtered Thin Film Section H Sputtered thin film technology provides years of worry-free measurements under demanding real-world conditions. Sputtered metallic strain gauge sensors have terrific thermal properties and superior stability specifications. Ideal for harsh applications demanding long-term service where precise laboratory-type measurements are required. 3100 Series — Delivers an output signal for both temperature and 4000 Series — The King of Stability: just 0.06% drift per year (noncumulative). A broad range of models include submersible, high...

PRESSURE SENSORS Switches Gems offers a choice of pressure switches, from compact cylindrical models for OEM use, to larger enclosed units for rugged process applications. A piston/ diaphragm design, incorporating the high proof pressure of piston technology allows these switches to operate with the sensitivity and accuracy of a diaphragm design. Repeatability ranges from 0.2 to 2% of the highest set point. Enclosures include aluminum, stainless steel, baked-on enamel coating, reinforced plastic and zinc-plated steel. All are NEMA4 or NEMA4X certified. Utilizing our proven pressure sensor...

SOLENOID VALVES Valves Proximity Switches General Purpose Providing 2- and 3-way functions and available in miniature and sub-miniature sizes, Gems general purpose solenoid valves deliver Flow Coefficients (Cv) of .018 to .880. Select from NPT port, manifold or barbed connection types. Body materials include brass, stainless steel, acetal, aluminum, and polypropylene. Versions within this group will control operating pressure differentials up to D 1000 psi (70 bar). Monitor proper closure of doors and access panels as part of an automated process with these compact sensors. Gems offers a...

CONTROLS Solid-State Intrinsically Safe Relays and Controls Standard Relays and Conductivity Level Controls Render any non-voltage-producing sensor, switch or conductivity electrode intrinsically safe with these relays and barriers from Gems. They amplify sensor load-handling capabilities in a wide range of AC and DC control switching applications. They are designed for easy installation in standard circuit boxes in non-hazardous areas. The amount of energy they send to sensors and switches within hazardous areas is insufficient to cause ignition of a specific hazardous atmospheric mixture...
