A sail switch, vane switch or flow switch is a mechanical switch that is actuated on or off in response to the flow or non-flow of a fluid such as air or water. [1] A sail switch typically operates through the use of a paddle or a diaphragm which gets displaced due to the force of fluid or air moving past it. Sail switches find application in ...
P&IDs are originally drawn up at the design stage from a combination of process flow sheet data, the mechanical process equipment design, and the instrumentation engineering design. During the design stage, the diagram also provides the basis for the development of system control schemes, allowing for further safety and operational ...
FCI operates a NIST flow calibration laboratory with 19 precision flow stands. FCI utilizes these precision flow stands to flow actual gases and reference fluids matched to the temperature, process conditions, and line size of individual customers' flow meter applications. The company has subsidiaries in Tilburg, Netherlands and Beijing, China.
A pressure switch is a form of switch that operates an electrical contact when a certain set fluid pressure has been reached on its input. The switch may be designed to make contact either on pressure rise or on pressure fall. Pressure switches are widely used in industry to automatically supervise and control systems that use pressurized fluids.
In 1996, IFS was listed in the Swedish stock exchange and the product was made into a component based one. This was followed with the launch of its web client and its establishment of an RnD center in Colombo. In 2001, IFS introduced Java-based mobile clients and Internet portals. In 2004, NEC acquired a 7.7% of IFS share capital. By 2005, IFS ...
A membrane potentiometer uses a conductive membrane that is deformed by a sliding element to contact a resistor voltage divider. Linearity can range from 0.50% to 5% depending on the material, design and manufacturing process. The repeat accuracy is typically between 0.1 mm and 1.0 mm with a theoretically infinite resolution.
A pedestal sump pump with a float switch. A float switch is a type of level sensor, a device used to detect the level of liquid within a tank. The switch may be used to control a pump, as an indicator, an alarm, or to control other devices. One type of float switch uses a mercury switch inside a hinged float.
The MAF sensor provides the open-loop controller predicted air flow information (the measured air flow) to the ECU, and the oxygen sensor provides closed-loop feedback in order to make minor corrections to the predicted air mass. Also see manifold absolute pressure sensor . Since around 2012, some MAF sensors include a humidity sensor. [1]
