Wireless Communications in Industrial Process Control
Electrical cables, for many years, were the only option for connecting measurement devices with their companion control and monitoring gear. While wired connections are still in widespread use, probably still the predominant connection method, wireless communication...
Rack and Pinion Actuator – Double Acting vs. Single Acting
Automating industrial valve operation requires numerous considerations in selecting the correct power source, drive type, torque range, and much more. The widest range of possible operating conditions should be anticipated and accommodated by the actuator selection to...
Steam Traps
Steam is widely used throughout industrial, commercial, and institutional facilities as a means of transferring heat energy, as well as a wide array of other applications. Steam generation cost is a substantial line item on almost any balance sheet, so deriving the...
Dual Application for Cooling Tower
Cooling towers are readily identified by their ubiquitous presence in large commercial cooling systems. They are an effective means of rejecting heat from a centralized liquid system. The general operating principle of a cooling tower involves a thermal and mass...
Vibration Dampening Improves Pressure Gauge Reading
Bourdon tube pressure gauges can exhibit rapidly oscillating indicators when subjected to pulsations from the measured line. The fast-moving pointer on the dial face makes it impossible for an observer to obtain an accurate reading from the gauge. One solution has...
High Visibility Process Gauges Deliver Improved Readability in Low Light Conditions
Process gauges can sometimes, by necessity, be located in areas with low lighting or other conditions that do not promote easy viewing and reading of their dial face. Winters Instruments, the manufacturer of a range of industrial instrumentation including dial face...
Closed Loop Cooling – Alternative Setup Delivers Benefits
Industrial processing often requires the transfer of heat, sometimes into the process, sometimes out of the process. External heat sources are often steam, hot water, or electric heaters. There are also instances where processing machinery either adds heat to the...
Forged Steel Valves for the Toughest Applications
Forging steel produces material of greater overall strength and toughness for parts and assemblies subjected to higher levels of stress. Forging is basically accomplished by applying localized mechanical pressure across the base steel, eliminating internal voids and...
Ergonomic Electro-Pneumatic Valve Positioner
Spirax Sarco, a global leader in steam system control products, has released a new valve positioner that ranks high on the user-friendly scale. The EP500 is an electro-pneumatic positioner that features a cast aluminum enclosure and a host of features that facilitate...
Metal Seated Ball Valves Offer Potential for Long Term Cost Savings
The majority of ball valves are provided with one of several elastomeric materials forming a soft seat between the trim, or ball, and the valve body. With the balance of the valve assembly in contact with the media likely to be metal (unless, of course, it is a...
