Recently, a large industrial firm presented several hydraulic test system manufacturers with a challenge: develop a system to simulate a field installation for factory set-up and testing. Naturally everyone jumped at the chance for a line-up. Then the required system’s capabilities were outlined as follows:
Many of our customers are now requiring their new servo-hydraulic test benches to be not only energy efficient, but to be designed to include the most environmentally friendly components and processes available. With this ever-increasing trend for “greener approaches”, Wineman has developed several solutions for adapting these new design practices into existing fluid power based test stand assemblies. Stand retrofits can combine several technologies, including energy conversion packages to more environmentally friendly system maintenance practices. In addition, WTI energy audits can provide a shopping list of possible upgrades, an upgrade cost analysis, and return-on-investment (ROI) studies to determine if your systems can “Go Green.”
Measuring analog signals within a data acquisition (DAQ) system is not always as simple as wiring the signal source leads to the measurement equipment. Data integrity is dependent on clean electrical signals being sent to and received from the electrical devices being controlled and monitored. Electrical noise can obscure these signals and make them unrecognizable, impairing an otherwise fine DAQ system. In this article, we are going to focus on coupled noise – noise from external sources that can affect the measurement signals in your system.
In today’s world of computer-based data acquisition and controls systems, mechanical components often outlive the electronics in the system. When this happens, the tester may function correctly but the components used to control it are out-of-date, unsupported, and could lead to extensive downtime should they fail. At this point, decisions need to be made about the system’s future.
