TCA-330

The LXT330FCA is a panel mounted, ready to use Free Chlorine Analyzer. The LXT330FCA features a plug and play design that incorporates a constant head flow control device, a pH sensor, a Chlorine sensor and the LXT330 analyzer/transmitter Free chlorine exists in solution as a pH dependent ratio of hypochlorous acid and hypochlorite ion. The Free Chlorine Sensor measures only the hypochlorous acid component of the free chlorine and the analyzer calculates the balance using either the measured pH or a user defined fixed value. The use of the pH sensor provides accurate compensation for samples between pH 6 and pH 9 eliminating the need for expensive sample conditioning systems to control the pH of the solution.

Amperometric chlorine sensors are flow sensitive, the minimum required flow by the sensor is 0.5 k/sec, above this value the output is virtually flow independent. A “Constant head” Flow control Device (CFD) maintains the optimum flow past the sensor over a wide range of incoming sample flow rates. The minimum flow required for the CFD is 10 gal/hr and the maximum flow is 80 gal/hr with the sample going to drain at atmospheric pressure.

Many competitive chlorine sensors require service on a monthly or bimonthly basis. The FCS uses a large surface area anode, combined with a large volume of electrolyte and a small cathode to provide operational cycles of up to a year without refilling.

For hazardous area installations, the Model LXT-380Exd offers ATEX/IECEx Exd Zone1IIC T4 certified Analyzer with NEMA-4X ingress protection.
