Torque overloads can cause serious problems for rotating machinery, but an understanding of torque limiting technologies can help engineers to enable more reliable operations Reliability, safety and productivity are key terms that come to mind when considering manufacturing plant operations,…
The activated sludge process (ASP) is designed to speed up the rate of decomposition of waste material in water. First developed in 1914, it remains an important means of treating both municipal and industrial wastewaters. This one-page reference provides information…
The new two-stage Sogevac NEO D rotary vane pump (photo) is equipped with a high-quality exhaust filter inside the oil casing. Built-in filtration reduces the required integration volume of the pump and ensures a cleaner environment without oil smoke or…
The new Allen-Bradley Micro 870 programmable logic controller (PLC; photo) can support applications that require up to 304 I/O points, 280 kB of memory and 20,000 program instructions. The Micro870 PLC uses a flexible design concept that provides designers up…
The E-finity (photo) is a continuous, dense-phase conveying system for fragile materials. Precise pressure monitoring and airflow corrections allow the system to operate efficiently under a wide range of conditions, while gently inducing materials through the conveying line in slug…
The MagnaShear motor brake (photo) employs oil shear technology that transmits torque between lubricated surfaces, thereby preventing wear on friction surfaces. A patented fluid-recirculation system dissipates heat, eliminating heat buildup, which is the most common problem in dry braking systems.…
The CGM 750 (photo) is a new cone mill with a diameter of 29.5 in. (750 mm) that gently grinds fatty, heat-sensitive, sticky, moist or fragile materials into uniform particle sizes with minimal fines at rates up to 32 metric…
The CL 10HY-V2 density cell and Series 2000 density digital converter (photo, p. 37) can be used to measure the density of ammonium hydroxide, caustic soda, ethylene glycol, methanol, nitric acid, oleum, phosphoric acid, sodium chloride and sodium hydroxide. The…
The Rosemount CX1100 in-situ oxygen analyzer (photo) is said to be the first high-performance, zirconia-cell-based combustion-control system designed to improve energy efficiency and meet environmental regulatory requirements for small and midsize boilers. It features the same sensor reliability found in…
The new 1209 pressure gage (photo) is equipped with a 316L stainless-steel solid front case and ring, along with a pressure-relief back cover to ensure that the process fluid will be directed away from the operator in the event of…
