This methodology facilitates multifactor testing. However, it comes at a price: a loss in power for detecting effects The traditional approach to experimentation — often referred to as the “scientific method” — requires changing only one factor at a time…
The U.S. Department of Labor's Occupational Safety and Health Administration (OSHA) and Mine Safety and Health Administration, in partnership with the National Institute for Occupational Safety and Health (NIOSH), have initiated a "Hear and Now – Noise Safety Challenge." According…
The FlowCam ALH automated liquid-handling system (photo) automatically processes up to 96 samples per run without requiring human involvement or supervision. This eliminates the potential for human error in sample handling and pipetting, and ensures that data are accurate. Ideal…
The recently launched ControlEdge programmable logic controller (PLC; photo), when combined with this company’s Experion Process Knowledge System, provides secure connectivity and tight integration to instruments, equipment and software from multiple vendors. ControlEdge is said to be the first PLC…
The Numatics 503 Series valve manifold (photo) enables end users to configure up to three safety circuits in a production machine. The manifold can create up to three independent electro-pneumatic safety zones, while also allowing independent non-safe sections to coexist…
After this company created the possibility to design GRP (glass-reinforced polymer) control stations for use in hazardous areas, it has now made this possible with stainless-steel local control stations with up to 15 modules (photo). The selection and placement follows…
With the basic segment coupler (photo) — the successor to SK1 and SK2 — Profibus PA nodes appear as DP nodes in the distributed control system (DCS) and can be configured and diagnosed without additional tools. The basic segment coupler…
The new wirelessly monitored Enardo 2000 emergency pressure-relief vents (EPRVs; photo) provide safety control by managing abnormally high storage-tank pressures in the oil-and-gas, chemical, petrochemical and pharmaceutical industries. Under normal operating conditions, an EPRV remains closed. The immediate knowledge of…
