Our most recent post addressed the benefits of proportional-only vacuum process control. Though this approach is well suited to many processes, in some cases more accurate (or precise) control of the pressure level is necessary. Under such circumstances, employing PI…
In our prior post, we talked about using variants of the classic PID algorithm in order to control vacuum processes. In the simplest form, the PID control loop can be reduced to a P-only, or 2-point, algorithm. For example, by…
Establishing good control over vacuum processes has numerous benefits, such as helping to improve process yields, achieve more repeatable results, and reduce process times. And there are several options for controlling vacuum processes to achieve these various benefits. This post…
In part 1 of this white paper, we reviewed the general advantages of using dry, chemical-resistant diaphragm pumps for process scale-up applications. In part 2, we will delve into the process of configuring the mini-plant in order to realize the…
Follow this guidance to understand today’s cybersecurity risk landscape and take the necessary steps to create a sound industrial control system cybersecurity program, including the development of a comprehensive, in-depth cyber-asset inventory In industrial facilities, cyber incidents typically result from…
Introduction Historically, mini-plants have utilized oil-sealed rotary vane vacuum pumps as a vacuum source because they provide relatively high flow rates and because they can reach relatively deep vacuum levels, such as 10-3 mbar. The same can be said of…
VACUUBRAND's dry, chemical resistant pumps provide an ideal solution for use in process development, scale-up work, and kilo labs. With no sealing fluid to replace, our dry pumps provide a low maintenance, low operating cost alternative to oil-sealed rotary vane…
A Midwest chemical plant serving the automotive and OEM market needed to replace an aging carbon steel horizontal cylinder bulk storage tank with a new stainless steel vertical cylinder tank. The customer needed an overfill protection solution for the tank…
Endress+Hauser non-contact radar measures level in corrosive chemical tanks A U.S. water treatment plant operating at 85 MGD capacity was in need of accurate and reliable level measurement for chemical tanks with product density variations due to temperature changes, without…
Pirani gauges are a group of indirect measuring pressure gauges which measure the thermal conductivity of the gas sample. Pirani gauges are typically used in the fine vacuum range (1 torr - 10-3 torr), as this is the range where…
