Paramagnetic oxygen gas analyser – ZAJ<\/strong><\/p>\n

Measurement of oxygen concentration in flue gases<\/p>\n

This analyser is used for continuous measurement of oxygen concentration in flue gases from boilers and industrial furnaces, for combustion control and optimization. It consists of a measurement probe combined with a signal converter. The probe is associated with a convection tube which is inserted into the flue gas to channel the gases to the probe for oxygen measurement. The converter (ZKM) is a microprocessor-based signal converter that manages inputs\/outputs, digital communication, display and control of the overall operation. The converter features advanced functions such as self-diagnosis of operation and probe regeneration, giving it very long stability.<\/p>\n

Features<\/strong><\/p>\n

    \n
  • \u2022 Fast response within 2 seconds
    \n\u2022 Precise, stable measurements with low sensitivity to interference
    \n\u2022 Very long (>12 years) sensor life, no contact with process gas
    \n\u2022 Robust, corrosion-resistant ZAJ paramagnetic technology with no moving parts<\/li>\n<\/ul>\n

    Fields of application<\/strong><\/p>\n

    Reliable process control for furnaces, metallurgy, semiconductor industry and gas separation.<\/p>\n","protected":false},"featured_media":85225,"template":"","meta":[],"product_brand":[],"product_cat":[89,152],"product_tag":[],"market":[113,114],"class_list":{"0":"post-80419","1":"product","2":"type-product","3":"status-publish","4":"has-post-thumbnail","6":"product_cat-gas-liquid-analysis","7":"product_cat-gas-analysers","8":"market-oil-gas","9":"market-process-and-chemical-industry","11":"first","12":"instock","13":"sold-individually","14":"shipping-taxable","15":"product-type-simple"},"yoast_head":"\nParamagnetic Oxygen Analyzer ZAJ FUJI ELECTRIC - Instrumentatie<\/title>\n<meta name=\"robots\" content=\"index, follow, max-snippet:-1, max-image-preview:large, max-video-preview:-1\" \/>\n<link rel=\"canonical\" href=\"https:\/\/instrumentatie.ro\/en\/product\/gas-liquid-analysis\/gas-analysers\/paramagnetic-oxygen-analyzer-zaj\/\" \/>\n<meta property=\"og:locale\" content=\"en_US\" \/>\n<meta property=\"og:type\" content=\"article\" \/>\n<meta property=\"og:title\" content=\"Paramagnetic Oxygen Analyzer ZAJ FUJI ELECTRIC - Instrumentatie\" \/>\n<meta property=\"og:description\" content=\"Paramagnetic oxygen gas analyser - ZAJ Measurement of oxygen concentration in flue gases This analyser is used for continuous measurement of oxygen concentration in flue gases from boilers and industrial furnaces, for combustion control and optimization.
