Gems Introduces a New Rugged Metal Electro-Opto Sensor

Gems® Sensors & Controls™ (Gems) introduces the new low cost, miniature ELS-950M Series of Electro Optic Level Sensors (ELS) for a wide range of applications and industries.

The ELS-950M Series expands on the existing ELS-950 product line with a brass housing to perform in harsh environments, maintain integrity in temperatures ranging from -40°F to +230°F and pressures to 250 psi.

ELS-950M liquid level sensors feature an over-molded electronics insert, TPE insulated wires, and a flurocarbon O-ring seal to create a watertight, environmentally resistant assembly. The ELS-950M is UL and CE approved to EMI standards and shock and vibration tested to MIL standards, IP66/67 and RoHS compliant. These robust sensors are available in 5 or 12 Vdc models with mounting options of ¼” NPT, ½”–20UNF-2B or M12x1-8.

“With the development of the ELS-950M Series, Gems has continued to expand the broad offering of our ELS product line,” says Kevin Castonguay, Product Marketing Manager for Gems Sensors & Controls. “The product delivers a robust and reliable solution for OEM customers. The small, solid state-sensor is durable enough to handle almost any application or temperature.”

The compact size, durability, and low cost of the sensor creates an excellent option for liquid level applications in medical diagnostic equipment, sterilizers, washers, dialysis equipment; lubricant systems in machine tools, generator sets, on- or off-road vehicles; hydraulic fluid reservoirs; HVAC and refrigeration systems; radiators and fluid overflow containers and OEM food and beverage applications.

Liquid Level Sensor for Food and Beverage Measurements

Stuff that sticks to the sides of the container makes accurate level measurements difficult. The LMT Series from ifm efector specifically addresses this problem for viscous media and powders in food and beverage processing tanks and pipes.   

High frequency (MHz) capacitive spectrum profiling technology enables the sensor to ignore foam and deposit build-up and differentiate between residue and actual product in a tank.

The solution involves sweeping the frequency band of 50 to 200 MHz for the capacitive sensor and taking three measuring points: electromagnetic field damping, permittivity phase shift of the molecule polarization in the magnetic field, and the media conductivity in the electric field. An algorithm in the sensor processes these measurements to calculate the signal amplitude.

GEMS Ultrasonic Continuous Liquid Level Sensor

Plainville, CT — Gems® Sensors & Controls™ (Gems) has launched the UCL-520 Series of Ultrasonic Level Sensors. The UCL-520 Series is suitable for non-contact applications such as industrial water treatment, wastewater management, chemical storage as well as many other challenging fluid applications.

The UCL-520 is a two-wire ultrasonic transmitter for measurement up to 26.2’ (8m) and is built with a rugged PVDF transducer for challenging ultra pure, corrosive or waste liquids. The highly accurate sensor is easy to install within limited space applications and the minimum 8” dead band allows for maximum fill of media. The UCL-520 offers a 3” (7.6cm) minimum beam width for restricted space applications and the selectable display indicates level in air gap or liquid height. The UCL-520 is push button calibrated with 6-segment LCD display and is broadly selected for corrosive media including atmospheric bulk storage, day tank and waste sump applications.

“Gems’ new line of ultrasonic level sensors offers our customers an innovative non-contact solution for both small and large tank applications. These highly accurate sensors provide flexibility and control for challenging fluid measurement applications” says Kevin Castonguay, Product Marketing Manager for Gems Sensors & Controls.
