Typically in an industrial set up, it may be necessary downstream of the main process application of superheated steam to reduce its pressure and temperatures to … Read more
A steam trap is a control valve whose basic function is to allow condensate to flow, while preventing the passage of steam until it has given up its heat by condensing back to water; in other words, a steam trap … Read more
Electronic IC temperature sensors are specialized integrated circuits that are used for sensing temperatures in the -55° C to +150°C range.
The working principle of IC temperature sensors is based on semiconductor physics. When … Read more
A new installation must be fully tested to ensure that the equipment is in full working order prior to its being started. This testing is typically divided into three phases:
Whereas superheated steam offers an excellent source of energy for mechanical power generation, in most cases, steam at greatly reduced temperatures, near saturation, proves a more desirable commodity especially for most heat-transfer applications. Precise temperature control is required to enhance … Read more
Valves are manual or automatic fluid controlling elements in a piping system; in other words, valves isolate, switch, and control fluid flow in piping systems. They are constructed to withstand specific range of temperature, pressure, corrosion, and mechanical stress. Valves … Read more
A volume booster is a device that amplifies or boosts the volume of air supplied to the actuator, that is, it takes an input signal and produces an output of a large volume flow of … Read more
Valve positioners are motion-control devices that are made in such a way to actively compare valve stem position against the control signal, adjusting the actuator diaphragm or piston till the correct stem position is achieved, that is, in a nutshell … Read more
Specific attention must be paid to instrument grounding, especially where field instruments are connected to a computer or microprocessor based control system. Where cable screens are used, ground continuity of screens must be maintained throughout the installation with the … Read more
A pressure reducing regulator is used in many industrial applications. In this article, we look at key parameters that must be established to help you make the appropriate selection of a pressure reducing regulator for your application.
