Features
CN117 two-wire explosion-proof industrial PH / ORP meter is developed by CNIC series of intelligent online chemical analyzer, environmental adaptability, simple operation and excellent test performance to have a high price, accurate measurement solution Of the pH or ORP value. Can be widely used in thermal power, chemical fertilizers, metallurgy, environmental protection, pharmaceutical, biochemical, food and water solution pH or ORP value of the continuous monitoring. The transmitter uses explosion-proof cast aluminum housing, good sealing performance Protection class up to IP67, especially for the site environment, unfavorable personnel long stay in industrial sites
Transmitter using two-wire system, 24VDC power supply, wiring simple. Output isolation 4-20mA, 4-20mA + HART, RS485, 4-20mA + RS485 standard DC signal can be provided to display, record, control, regulation and other instruments or PLC, DCS, FCS system.
High intelligence: CN117 industrial PH / ORP transmitter using high-precision AD conversion and micro-controller micro-processing technology to complete the pH measurement, temperature measurement, automatic temperature compensation, instrument self-test and other functions.
High reliability: components highly integrated, without the complexity of the function switch and adjustment knob.
Anti-interference ability: The latest devices, impedance up to 1012Ω; current output using optical isolation technology, anti-interference ability to achieve Far EasTone. With good electromagnetic compatibility.
Waterproof and dust-proof design: protection class IP67, suitable for outdoor use
25 ºC Conversion: pure water and ammonia added to the ultra-pure water at 25 ºC reference temperature conversion, to achieve a 25 ºC shows the pH value, especially for a variety of water quality measurement of power plants.
Communication: RS485, HART to choose from, easy to join the computer for monitoring and communication.
Intrinsically Safe Explosion-proof: Intrinsically safe design, explosion-proof mark ExiaIICT6Ga is used for zone 0, zone 1, zone 2.
