1、 Product Introduction:

　　Online plug-in integrated explosion-proof pH meter

It is one of the SWM-X100 series intelligent online chemical analyzers developed by our company. With strong environmental adaptability, simple operation, and excellent testing performance, it has a high cost-effectiveness and can measure the pH value of solutions. It can be widely used for continuous monitoring of pH values in solutions such as thermal power, chemical fertilizers, metallurgy, environmental protection, pharmaceuticals, biochemistry, food, and tap water. The transmitter adopts a cast aluminum shell with good sealing performance and a protection level of up to IP67, which is particularly suitable for industrial places with harsh on-site environments and unsuitable for prolonged personnel stay.

The transmitter adopts a two-wire system, powered by 24VDC, and has simple wiring. Can output 4-20mA for display, recording, control, regulation and other instruments or PLC, DCS, FCS systems.

Compliant with GB3836.1-2010 "Explosive Atmosphere Part 1: General Requirements for Equipment" and GB3836.2-2010 "Explosive Atmosphere Part 2: Equipment Protected by Flameproof Enclosures" standards; The symbol is Ex d IIC T6 Gb.

2、 Basic performance:

　　High intelligence:The SWM-X100 integrated explosion-proof water analyzer's two-wire industrial pH transmitter adopts high-precision AD conversion and single-chip microcomputer processing technology, which can complete various functions such as pH measurement, temperature measurement, temperature automatic compensation, and instrument self-test;

　　High reliability:The components are highly integrated, without complex functional switches and adjustment knobs;

　　Strong anti-interference ability:Using components with an impedance of up to 1012 Ω; Strong anti-interference ability of current output, achieving long-distance transmission. Has good electromagnetic compatibility;

　　Waterproof and dustproof design:Protection level IP67, suitable for outdoor use;

　　25 ℃ conversion:The 25 ℃ reference temperature conversion was carried out for pure water and ammonia added pure water, achieving the display of pH value at 25 ℃, which is particularly suitable for measuring weak conductivity water quality such as desalinated water in power plants or chemical plants
