This company has launched the first in a new line of high-performance intelligent drive module (IDM) products. The IDMsm (photo) is a two- or four-axis EtherCAT DS402 universal servo drive featuring unique control algorithms and processing technologies that enhance the…
The Xover solenoid valve (photo) is designed to switch quickly and efficiently between samples, reagents, cleaning solutions or calibrants. The Xover valve features a Y-shaped elastomer tube in a three-way configuration, which results in a design that combines the flow…
Waterhammer arises because of sudden changes in fluid flow, and can present significant problems in processes that involve flowing liquids. This article outlines these potential issues and offers guidance for handling the pressure changes arising from waterhammer Most large-scale processes…
This pictorial guide illustrates some of the common problems that can occur with polymeric and elastomeric materials that differ from those that occur with metallic seals and components Failures of polymer (plastic and elastomeric) parts and their consequences can be…
This overview compares various sealing technologies, and points out advantages and disadvantages of applying different mechanical-sealing designs for caustic fluids Caustic applications in chemical plants can play havoc on the mechanical seals of rotating equipment. These applications can be difficult…
The new Humicap HMT370EX series of intrinsically safe humidity and temperature transmitters (photo) are designed specifically for hazardous and explosive environments. The entire transmitter can be installed directly in explosive areas, up to Zone 0 and Zone 20, with no…
