The use of INPUT/OUTPUT software filters can provide enhanced performance of controllers to process systems conditions. The use of Input filters are to reduce the erratic fluctuations of the analog input signal due to either electrical “noise” conditions or rapid fluctuations of the analog input signal. It accomplishes this by slowing down the response of the analog input to a change.
Learn how to set up data logging in the Watlow F4T controller.
Introducing the F4T with INTUITION® from Watlow Combining the flexibility of a modular I/O with best-in-class ease of use, the F4T could very well make user manuals a thing of the past.
For new liquid filtration applications – or if you are considering upgrading your system – consider the benefits of Cardinal's High Flow Cartridges over traditional 2.5” pleated or depth filters.
Selecting materials for a given application is one of the main design steps towards a safe and cost efficient system, yet a commonly overlooked stage, mainly performed from a purely economic standpoint.
ZWICK's check valve TRI-CHECK combines all the benefits of their TRI-CON Series in a non-return valve. Triple-offset design with a wide seat angle and a true cone in cone, no rubbing while moving and absolute zero leakage performance.
TRI-CON valves incorporate a unique third offset with a 25-degree incline, eliminating the friction between the laminated seal ring and the body seat. The resulting camming action allows the stainless and graphite laminated seal ring to seat into an inclined 25-degree body seat. Learn more.
In Jon Monsen's book, Control Valve Application Technology (published and distributed by Valin Corporation), Jon explains how to properly size and select a control valve. Jon recently received inquiries from customers interested in a further explanation of one of the graphs featured in his book. This article will cover that explanation.
Valve sizing and proper application of control valves have always gone hand-in-hand. However, the tools available to valve users have changed and improved significantly over time.
A refinery was injecting a catalyst into their process stream to strip out the propane-impregnated HF gas (mixed gas is a by-product of the FCC process), but the catalyst would only work at temperatures above 385°F. Valin's process team analyzed the situation and made recommendations. Learn more.
A lesson for me is that I need to involve you earlier in the program.
You were tireless in your support and it will not be forgotten!
