Tough metal electro-optic liquid level sensor introduced

Gems Sensors & Controls, a global leader in liquid level, pressure, and flow sensors, miniature solenoid valves and fluidic systems, has introduced a new compact, durable, and low cost Electro Optic Level Sensor (ELS) for liquid level sensor applications.

The ELS 950M expands on the existing ELS 950 Series and will benefit OEMs and end users in a wide range of industries and environments.

Encased in a brass housing, the new ELS 950M liquid level sensor features an over-moulded electronics insert, TPE insulated wires, and a fluorocarbon O-ring seal to create an air- and watertight resistant assembly that is able to perform in harsh environments. This sensor can maintain integrity in temperatures ranging from -40°C to +110°C and pressures up to 17 bar.

The ELS-950M has been rigorously developed to meet the demands for a wide range of industry applications and is approved to UL Recognition, CE marked to EMI standards, shock and vibration tested to MIL standards, ingress protected to IP66/67 and is RoHS compliant for hazardous materials.

These robust sensors are available in 5 or 12VDC models with mounting size options of 1/4” NPT Male, 1/2”-20 UNF-2B or M12x1.8 straight thread.

Kevin Castonguay, product marketing manager for Gems Sensors & Controls said: “With the development of the ELS-950M Series, Gems has continued to expand the broad offering of our ELS product line.

"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 makes it ideal for a variety of point level liquid sensing applications in medical diagnostic equipment, sterilisers, 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.
