Conductivity Monitoring Applications

  • Construction Xray Inspection

    A non destructive test for concrete plays a central role in determining the quality of cement casting. Bubbles and sediment in the cement weaken the construction considerably. NDT testing equipment is also used in construction to determine the quality of the wired foundations. One of the challenges of construction NDT is the possible difficulty in reaching testing locations. A non destructive test for concrete conducted with a portable digital radiography system provides an excellent inspection tool. Combining mobility with phenomenal penetration capabilities and the highest quality digital radiology imaging, Our portable X-ray inspection systems provide a comprehensive solution to construction NDT technicians.

  • Prescribed Burning

    A general understanding of the separate and combined effects of several weather elements on fire behavior is needed to plan and execute a good prescribed burn. Because weather and fuel factors interact, an experienced prescribed burner can conduct a successful burn even with one or more factors slightly outside the desired range—as long as they are offset by other factors. Accurate fire weather monitoring of fire danger indices via the RAWS network, providing historical data leading up to a prescribed burn is critical in the planning stages. However, having accurate weather conditions in a micro-climate scale in real time during the execution of a prescribed burn is just as critical. The weather variables most applicable to prescription burns are air temperature, relative humidity, wind direction, wind speed and precipitation. A combination of wind speed, relative humidity, temperature, and solar insulation largely determines fuel condition which in turn affects fire behavior.

  • Measurement and control systems for the Boiler water monitoring

    In ongoing operation, the substances suspended in the boiler water are concentrated. In order to avoid the negative consequences (foaming, deposits) of excessive salt content in the boiler water, specified limit values must not be exceeded. With the aid of a desalination control valve, boiler water with concentrated content is constantly removed and replaced with clean water. If the limit values are exceeded, the conductivity limitation ensures prompt switching off of the burner(s). Foreign substances that have sunk to the bottom of the boiler are removed by briefly opening a drainage valve.

  • Wireless multiple parameter monitoring

    Monitoring multiple sensing points including fill level, pH, conductivity, and flow—often from varied locations in a large water treatment plant—can be a challenge. With four analogue inputs, a single SureCross Node can easily centralize and transmit critical monitoring information from multiple Sensors or controllers. Banner’s unique power management capability enables a single Node equipped with a FlexPower™ optimized QT50U or T30UX ultrasonic analogue sensor (level detection) to operate for years on a single DX81 battery power supply.

  • Measurement and control systems for the Limiting the level - electronically

    A distinction is made between low water (LW) and high water (HW) limiters. Whereas LW limiters are in principle required for the safe operation of a plant in accordance with European regulations, HW limitation (overfill protection) is required only in accordance with TRD 604 for 72-hour operation.

    Ultra pure water treatment

    Ultra pure water is mainly used in the semi conductor and pharmaceutical industry. Because of the continuing miniaturilisation in the semi conductor industry, the specifications become more strict every year. Ultra-pure water contains by definition only H20, and H+ and OH- ions in equilibrium. Therefore, ultrapure water conductivity is about 0,054 uS/cm at 25oC, also expressed as resistivity of 18,3 MOhm.

    pH value and conductivity measurement for power plants

    The pH value and the conductivity have to be determined quasi-continuously at numerous locations in a power plant. The pH value is a key parameter to control the amount of lithium hydroxide that has to be added to the primary circuit of a pressurized water reactor; in water steam circuits, the pH value controls the amount of added amines. The conductivity indicates the amount of dissolved minerals. It is a measure of the water purity and is one of the most important parameters for any chemical control program in a power plant. It is determined at numerous sampling points in the power plant, for example, in the cooling water circuit, in feed and makeup water, at the outlet of the condensate pump, and in the primary circuit of a pressurized water reactor.
