About Gems Sensors

The company's catalogue includes liquid-level, flow and pressure sensors, solenoid valves, digital panel meters and proximity switches. The brand's flow rate sensors are ideal for measuring the velocity of water while determining the sediment transport of a stream or calculating the stream's discharge value. These Gems flow sensors provide flow rates ranging from 0.026 to 6.6 GPM and burst pressures up to 2500 PSI. They feature housing made of nylon 12 / Noryl for high dimensional stability and deliver viscosities up to 81 SSU. They offer maximum accuracy of +/-3 % and are capable of being operated at temperatures ranging from -4 to 212 degrees F. FS-500 Series flow switches by Gems are used in water treatment applications including purifiers, heaters and chlorinators. They feature polypropylene bodies for high flexural strength and deliver flow rates up to 5 GPM. These flow switches provide a 3/4 FNPT connection for leak-free seal and withstand ambient temperatures up to 212 degrees F.

Things To Consider

Cross-Reference Alternatives

Some Gems Sensors MPNs cross individual references to the equivalent Dayton model numbers. So, if you're looking for a competitor item that is either out of stock or obsolete, chances are Raptor Supplies has the equivalent Gems Sensors products available.

Shipping

These Gems Sensors products range from small to large sizes. They may require careful packaging as some items might get damaged while shipping. Hence, these Gems Sensors items are delivered by courier shipment and air freight for minimum downtime.

Gems Sensors Competitive Advantages

SureSite Visual Liquid Level Indicators

These visual level liquid indicators continuously indicate liquid levels in vessels and storage tanks. They are visible from over 30 m and are compatible with fluids like PVDF, alloy 20, Hastelloy C 276 and titanium. These SureSite visual liquid level indicators feature a permanent magnet enclosed into each flag, providing a safe magnetic interlock with adjacent flags, ensuring proper alignment while protecting against vibrations, shocks, surges or rapid level changes. They have a magnetic guide that enables the use of a powerful bar magnet in the float assembly. These visual level liquid indicators are virtually maintenance-free and come with continuous level transmitters and attached optional point level switches for extending capabilities beyond simple sight glasses.

Psibar Pressure Transducers

Psibar transducers are engineered using plasma-enhanced Chemical Vapour Deposition (CVD) technology. This technique uses a chemical vapour for depositing thin layers of silicon and silicon dioxide on a stainless steel substratum, thus forming a very sensitive and precise polysilicon strain gauge. Psibar transducers are less sensitive and more stable to pressure cycling and thermal exposure than silicon-based pressure transducers. These transducers are manufactured in an automated, zero-defect process that combines configuration, calibration and test systems for improving quality and sensor accuracy. They feature a thicker diaphragm to handle pulsating pressures and an ASIC chip programming to provide more linearity correction than conventional thermal compensation methods.

Frequently Asked Questions

What are the uses of Gems ultrasonic switches and transmitters?

Ultrasonic switches and transmitters by Gems Sensors are designed for applications requiring solid-state level measurements.

What is the accuracy of Gems TurboFlow sensors?

Gems TurboFlow sensors provide accuracies up to ±3 % of reading and 0.5 % repeatability while measuring flow rates from 0.1 to 8 GPM.

What does SPST or SPDT switch mean?

SPST means single pole, single throw, indicating that the product can control one circuit with only one On position. SPDT means the switch is a single pole double throw, indicating that it has two ON positions.

Will different liquid media affect the time delay for Gems optic sensors?

For similar viscosities, the time delay would be the same for different media.
