Flow switches are mechanical devices used in controlling the flow of air, steam, or liquid A flow switch operates by conveying a trip motion (relay, reed switch, paddle) to another machine within the system, usually a pump The trip signal will indicate to the pump to turn on or turn off. Let’s start with the most basic float switch a twowire, singlepole, singlethrow float switchThe rising action of the float can either close (ie, turn on) a “Normally Open” circuit, or it can open (turn off) a “Normally Closed” circuitInstallation scenarios might include a Normally Open float switch turning on a pump to empty a tank (Control Schematic 2), or a Normally Closed. The flow switch can easily be tested without having to disconnect the electrical leads or dismantling the switch A simple multimeter is all you need to effectively troubleshoot your flow safety device Contact ATI of New York The experts at Applied Technologies of New York specialize in all things boiler.

The principle of operation is quite simple Air flow exerts a force on a paddle, actuating a dusttight SPDT micro switch The switching point may be adjusted continuously within a wide range, making the LPS useful in a wide variety of applications The flow switch is factory set to switch at 195 FPM.

Symbols of Electronic Sensors The sensors are transducers and electronic detectors activated by the energy delivered by a system and that in turn deliver another type of energy to another different systemThe transformed energy may be of physical, chemical or biological origin.

Their application areas range from simple monitoring tasks as an on/off switch to precise digital flow rate measurements Use the “Select By Application” tool to narrow your search for a flow sensor based on media type, and read more about the underlying measuring principles and technology of a sensor group by accessing the orange “Learn. The mechanism of a switch may be operated directly by a human operator to control a circuit (for example, a light switch or a keyboard button), may be operated by a moving object such as a dooroperated switch, or may be operated by some sensing element for pressure, temperature or flow A relay is a switch that is operated by electricity. Flow Sensors symbols for use in electrical, pneumatic and hydraulic schematic diagrams Available in SVG, PNG, JPG, DXF & DWG formats.
