Liquid analyzers are used for monitoring process chemistry including water quality, providing process optimization and control. Common measurements include pH, ORP, Liquid analysis is essential for protecting capital assets including boilers and cooling towers, by preventing corrosion, minimizing maintenance, and maximizing uptime. Yokogawa is a recognized world leader for reliable liquid analytical equipment, providing accurate and repeatable solutions for maintaining and controlling even the most demanding process applications with unparalleled ease of operation. 2-wire loop powered and 4-wire analyzer available with HART, 4 kinds of measurements; pH/ORP, SC, ISC and DO, Dual sensor measurement on a 2-wire type analyzer pH/ORP , SC and SC, and DO and DO available pH and ORP meters, analyzers and transmitters are used for continuous process monitoring of pH and ORP to ensure water/product quality, monitor effluent discharge, batch neutralization, pulp stock, scrubbers, cooling towers, chemical, water/wastewater treatment and many other applications. The PH20, FU20 and FU24 all-in-one sensors show how Yokogawa applies the motto "Simple is best" to sensor technology. These sensors feature four separate elements (pH, reference, temperature, ORP) allowing for simultaneous measurement of pH and ORP is possible with one sensor in a rugged Ryton or PVDF (FU20), Ryton (FU24) or PVDF (PH20). The integral or vario-pin cable comes number-coded cable along with the integral NPT threads on the sensor makes installation convenient. The Quick Release Adapters for the FU20 allow easy removal of the sensor for cleaning and calibration
Liquid analyzers are used for monitoring process chemistry including water quality, providing process optimization and control. Common measurements conductivity. Conductivity is the measure of a solution's ability to pass or carry an electric current. The term Conductivity is derived from Ohm's Law, E=I•R; where Voltage (E) is the product of Current (I) and Resistance (R); Resistance is determined by Voltage/Current. When a voltage is connected across a conductor, a current will flow, which is dependent on the resistance of the conductor. Conductivity is simply defined as the reciprocal of the Resistance of a solution between two electrodes. When Contacting Sensors are used, the conductivity is measured by applying an alternating electrical current to the sensor electrodes (that together make up the cell constant) immersed in a solution and measuring the resulting voltage. The solution acts as the electrical conductor between the sensor electrodes.
Liquid analyzers are used for monitoring process chemistry including water quality, providing processoptimization and control. Common measurements Dissolved oxygen.Dissolved oxygen (DO) is a liquid process measurement for determining the amount of oxygen dissolved orcarried in the process liquid. There are three common technologies for dissolved oxygen measurements: polographic, galvanic and optical. The standard units of measure are milligrams per liter (mg/l), parts permillion (ppm), parts per billion (ppb), or % saturation. The DO30G sensor for dissolved oxygen is designed for use in water treatment plants such as sewage treatment works, effluent activated sludge process, and potable water treatment. It is also effective in river monitoring, intake protection, fish farming and other fields where water quality is important. This galvanic cell has a fast response time and good long term stability, and features replaceable diaphragm and cable for easy maintenance. A temperature sensor is incorporated for compensation. The DO30G sensor can be used in either the floating ball fitting or in the immersion fitting.
Get a Long Service Life and Stable Operation with a Zirconia Sensor Sensor Replacement is Easy” Yokogawa's zirconia oxygen analyzers are used for combustion monitoring and control in a wide variety of applications and help industries to make considerable achievements in energy saving. The applications range from energyconsuming industries, such as iron and steel, electric power, oil and petrochemical, ceramics, pulp and paper, food, and textiles, to various combustion facilities, such as incinerators and small- and medium sized boilers. Combustion monitoring and control using the analyzer also contribute to a lowering of CO2, SOx, and NOx emissions by allowing for more complete combustion, thus preventing global warming and air pollution. A molecular bonding method completes installation of platinum electrodes, and its inherent connection prevents separation of platinum from the zirconia element. A lead-less electrode design eliminates electrical disconnection. Special coating protects the platinum and prevents the sensors from deteriorating or becoming damaged. No special tool is required for cell replacement. Whenever required, the cell is easily removed by removing four screws from the top of the probe. Down time ("from the time installation is started until it is completed") is minimized to approximately ten minutes. After the cell is replaced, the analyzer requires a zero and span calibration only once.
