Industrial Free-chlorine Analyzer Now FM/ATEX/IECEx Approved for Hazardous Processes & Plant Areas
Ideal for Chemicals, Electric Power Generation, Food Processing, Oil/Gas Refining, Pharmaceuticals, Pulp/Paper and More
Wherever free chlorine is measured to assure water purity, cleanliness or disinfection in hazardous industrial processes and plants, the FM/ATEX/IECEx approved Model FCX80 Free-Chlorine Analyzer from Electro-Chemical Devices (ECD), will help engineers and technicians get the job done in a safe manner.
With its FM approved and ATEX/IECEx compliant design, ECD’s FCX80 Analyzer is certified for hazardous locations where combustible gases can be present in water treatment areas, helping prevent hazardous situations that could jeopardize employee safety, plant equipment and the surrounding area. Such gases have been responsible for serious accidents causing loss of life and catastrophic facility damage. This analyzer is designed for demanding applications, such as raw food processing rinse water, beverage pasteurization, cooling tower and boiler water scale prevention, pulp/paper bleaching operations, wastewater effluent treatment and much more.
The panel mounted FCX80 Analyzer is a ready-to-use free chlorine analyzer intended for hazardous locations. It is designed to monitor free chlorine in drinking water, rinse water, cooling water or other fresh water samples from 0.05 to 20 ppm chlorine as the standard range or 0.01-5.00 ppm with the optional low range sensor. The FCX80 is also compliant with U.S. EPA Method 334.0 for drinking water treatment.
With its intrinsically-safe, explosion-proof barrier design, this analyzer’s Model S88 Free Chlorine Sensor provides accurate and reliable measurement via its advanced digital communications. The sensor’s no-reagent design features amperometric sensing based on polarographic technology relying on gold/silver materials and a PTFE membrane. The sensor operates over a wide temperature range from 0 to 50°C (32 to 122°F). Response time is T90 in 2 minutes. The only maintenance needed is replacing its economical electrolyte solution at intervals of up to 12 months.
Free chlorine exists in solution as a pH dependent ratio of hypochlorous acid (~100% at pH 5) and hypochlorite ion (~100% at pH 10). Chlorine has been a popular disinfectant for water treatment to ensure public health and in support of a wide variety of industrial processes. Disease causing organisms such as Cholera, Hepatitis A, Typhoid Fever and Dysentery, as well as corrosion causing bacteria are eliminated with Chlorine, along with slime, algae and molds that can grow in water storage facilities such as plant reservoirs and storage tanks.
The plug-and-play design of the FCX80 Analyzer is easy to install and incorporates a constant head flow control device, a pH sensor for dependable measurement. The free chlorine sensor and the transmitter are all conveniently mounted on a PVC panel. Technicians simply connect the sample and drain lines, connect the power and outputs, and the FCX80 Analyzer is ready to use in less than 30 minutes.
A 24-VDC powered device, the FCX80 Analyzer’s transmitter comes with a 128-x-64 pixel LCD display with black graphics and/or type on a grey or white background with an LED backlight. This easy-to-read display allows parameters to be graphically displayed with a user defined line, bar or gauge style graph. The transmitter is packaged in a rugged stainless steel and meets the requirements for FM approval, Class 1, Div 1, Groups A, B, C, D, E, F and G, as well as ATEX and IECEx for Zone 1 requirements.
For ease of plant management, the FCX80 Analyzer is compatible with supervisory control and data acquisition (SCADA) systems or large distributed control systems (DCS), including a 4-20 ma output. The standard configuration features two 4-20 mA outputs, three single-pull/double-throw (SPDT) alarm relays and a MODBUS remote telemetry unit (RTU). Digital HART communications is also available.
