Flow - FCI - Flow Switches
Liquid Flow Switches and Air/Gas Flow Switches for Industrial Process Measurement and Automation FCI Flow Switches feature thermal dispersion technology in which the temperature difference is greatest in a no-flow condition and decreases as flow increases, cooling the heated RTD. Changes in flow velocity directly affect the extent to which heat dissipates and, in turn, the magnitude of the temperature difference between the RTDs. An electronic control circuit converts the RTD temperature difference into a DC voltage signal. Both of these signals are provided at output terminals and are used to drive two adjustable-setpoint alarm circuits. Both alarms are independently field configurable for flow, liquid level/interface or temperature operation. FCI has designed and developed four standard thermal flow switch product series to meet a broad range of performance and environmental application requirements. Each FCI flow switch group can be distinctly identified by the following listed general instrument characteristics FlexSwitch Series: For Process Temperature Changes up to 100°F (38°C)

Switch, Network Switch - What is a Switching Hub
Switch, Network Switch A switch ( switch ing hub ) in the context of networking refers to a device which filters and forwards data packets across a network. Unlike a standard hub which simply replicates what it receives on one port onto all the other ports, a switching hub keeps a record of the MAC addresses of the devices attached to it. When the switch receives a data packet, it forwards the packet directly to the recipient device by looking up the MAC address. A network switch can utilise the full throughput potential of a networks connection for each device making it a natural choice over a standard hub. In other words, say for instance you had a network of 5 PCs and a server all connected with 10Mbps UTP cable, with a hub the throughput (10Mbps) would be shared between each device, with a switch each device could utilise the full 10Mbps connection. When using a switch instead of a hub it is common place to create a faster throughput connection between the switch and the server (backbone). For example if you had 10 PCs connected to the switch with 10Mbps cable then it would improve performance to use a 100Mbps connection from the switch to the server. © Copyright 2001-2008 helpwithpcs.com Back to Computer Dictionary

Light switches, remote light switch, & wall switches by Home Controls
Ever forgotten to turn off the light on the back patio? With home automation you can access that light switch and cause it to turn off at the touch of a button on your remote control. Direct control of your home lighting is a powerful home automation benefit. That is why this product category has so many options. Wall switches can send commands to other devices in your home (transmitters) and control them, or they can simply receive control commands (receivers) and turn on, off or dim. Sometimes they do both. Principal manufacturers of controlled wall switches are Leviton, X-10, PCS, Lightolier and Simply Automated. Home Controls also carries On-Q/Legrand Advanced Lighting Control (ALC) switches which are directly wired to your home automation system through hubs or concentrators.
