. kyNon impact level and load measurement for your tank Alfa Laval Weighing Systems UltraPure . Application The Alfa Laval weighing system is designed to be integrated with Alfa Laval tanks legs and offers a high precision and non impact measurement of weight, ideal for mixing, dosing, level or batch tasks. Main features: - Robust and shockproof, can tolerate up to 300% overload or side load - Load cells are produced in stainless steel and hermitically sealed to IP68 - Designed for Clean rooms - Hygienic design for sanitary installation - Simple and fast mechanical installation without mounting kits - Load cells are pre-calibrated - Load cell calibration are independent of cable lenght - Simple electrical installation, plug and play - Integrated diagnostic feature for detailed diagnostic and surveillance of weighing system - Load cells are ATEX certified for zone 1 and 2 - Load cell cable lengths up to 50 mtr Standard range The Alfa Laval weighing system is a complete process solution offered for process weighing installation where level measurement, mixing, dosing or batching is required. The weighing solution is as standard delivered in three different accuracy ranges: 2%, 0,1% and 0,05% with a total measuring range from 0 to 32000 kg. Each weighing system consists of a number of load cells including load cell modules and an electronic output module. The output modules are available with both analog 4-20 mA and digital (Profibus DP and DeviceNet) outputs. For high hygienic demands the load cells are offered as electropolished and hermitically sealed to IP68 with laser welding. Alfa Laval offers an additional range of tank legs that fits to the load cells ensuring a robust and reliable connection between the tank and the load cells. In hazardous areas, Alfa Laval offers Load cells suited for installation in ATEX Zone 1 and 2. Working principle The Alfa Laval shockproof digital load cells are based on a patented capacitive measurement principle where a non-contacting capacitive sensor is mounted inside the load cell body. As the capacitive sensor is not in contact with the load cell body, the load cells are to a very high degree unaffected by overloads, sideloads, shocks and welding voltages. Therefore straightforward mechanical installation of the load cells can be done without expensive complicated mounting kits and overload protection devices. The electrical installation of the digital load cells is pure plug-and-play as the signal from the non-contacting capacitive sensor is directly converted, compensated and calibrated by a patented ASIC. The digital signal is transmitted as RS485 data on a low-cost RG-58 single wire coaxial cable which may be up to 50 meters long. The calibration of the digital load cells is independent of the load cell cable length.
