They also ensure that tanks do not run too low, possibly interrupting production. Switches can be inserted into pipes to indicate when a pipe is empty. This protects pumps from “running dry” and causing damage. Point level switches can be used independently or in conjunction with continuous level devices. CertificationsSwitching instrumentation is designed for certification compliance with the following programs:VEGA offers a wide variety of application-specific solutions for measuring level. In addition to providing instrumentation for reliable continuous level tracking, VEGA produces numerous technologies designed for point level switching. Switches can detect the absence and presence of process materials, and provide critical overfill protection and discrete alarming in both solids and liquid applications. With such a broad range of switching capabilities, VEGA continues to lead the way in solving difficult and important measurements in the process industries. ? ATEX Standard ? CSA ? FM Standard ? GOST-R Standard ? SIL2 ? IECEx ? WHG ? 3A ? FDA ? ABS4Principles of OperationVibration—LiquidsThe VEGASWING uses the Piezo vibration principle. The frequency of the vibration changes when the vibrating fork at the end of the sensor is covered by the product. The VEGASWING detects this change and triggers the switch command.Vibration—SolidsThe VEGAVIB and VEGAWAVE detect powders, granules, and solids. The sensor continuously vibrates from energized piezoelectric crystals. When the process covers the sensor, the vibration is dampened, prompting the electronics to trigger a switching command. VEGA offers several types of point level detection technologies, operating with different types of measuring principles. All VEGA point level technologies process a change in operating conditions as a switching command for discrete, high, and low level alarming and measurement. 5CapacitiveThe VEGACAP and vessel form the two electrodes of a capacitor. A capacitance change caused by a level change is processed by the integrated electronics and then converted into a switching signal.Microwave BarrierThe VEGAMIP system consists of a microwave emitter and a receiver. A signal with a frequency of 24 GHz is focused by an antenna system and emitted toward the receiver. Process material in the path of the rays attenuates the signal at the receiver and the change in energy is evaluated and converted into the appropriate switching output.“VEGA offers switches that are used as either overfill or dry run protection in both liquids and coarse media with a number of different technologies.”6Increased Information and CertaintyWhen only point level detection is required, a single instrument can be used to indicate a high or low level. As a series, switches are used to indicate the status of multiple points in a vessel. Adding switches provides more detailed information about the vessel to the user. When point level switches are used in conjunction with a continuous level device, truly redundant systems can be developed. The point level switch acts independently from the continuous level device. The safest systems utilize a diversity of technology, which lowers the chance that a single process condition upset causes both sensors to read incorrectly. VEGA point level switches are available in a variety of chemically resistant materials and electrical outputs, and are designed for use in all types of hazardous areas. Explosion proof sensors are available for use in detecting bulk material in chemical plants. Highly polished, cleanable sensors are offered for use in food and pharmaceutical facilities. With industry-specific requirements in mind, VEGA supplies point level technologies for use in every industry.VEGA offers multiple technologies and options to ensure that the best technology is chosen for any given industry application.Every industry places its own very specific demands on measurement technology.
