California-based Electro-Chemical Devices (ECD), manufacturer of liquid analytical process instrumentation, has introduced models S10 and S17 Universal Toroidal Conductivity Sensors, which the company claims, enable highly accurate conductivity measurement. The inductive sensors feature a standard measurement range from 50 to 1,000mS. Model S10 is an immersion or insertionstyle device and Model S17 is a valve retractable-style device.

According to ECD, the sensors are built with the toroids, in line with the axis of the sensor, instead of perpendicular to the axis, as is commonly employed. This allows for the smaller diameter and shorter inductive path length, that is beneficial for the compact design.

With a compact 0.75-inch (19.05 mm) diameter sensor body design, the conductivity sensors, claims ECD, are ideal for use in tight places with crowded piping and equipment locations, such as, cramped industrial process and manufacturing operations.

They operate effectively in pipes as small as 1.5 inches (38.1mm) in diameter, which is up to five times smaller than typical conductivity measurement devices. Fitting into an existing pipe, without the need for re-plumbing the flow cell, is an added advantage.

Product features and applications:

• The sensors feature Kynar PVDF plastic body that is sealed, making them suitable for harsh industrial applications, including resin bed regeneration, acid and alkaline scrubbers, metal-plating baths and wastewater treatment.

• They can withstand harsh liquids such as acids and coolants, where corrosion and scaling pose problems.

• The models are compatible with ECD’s transmitters and controllers. The T23 and T28 loop-powered transmitters can be used either with NEMA 4X, T23, or explosion-proof T28, area classifications. The C22 controller has dual-sensor inputs that allow any combination of measurements and outputs to be combined in one controller.
