SIKA Flow Switches - Baccara

1 sika Flow SwitchesSIKA Flow SwitchesReliable - Safe - Proven !Our tried-and-tested flow monitoring Switches are used fortwo basic purposes: To ensure a minimum flow rate, cooling water or lubricating oil (protectsagainst running dry). To start a technical procedure when the flow flow monitoring switch comprises a paddle system( 1 )to whose end a permanent magnet is attached (2).Abovethis magnet is a reed contact (3), located outside the flow offluid. A second magnet with opposing poles(4) creates theforce necessary to reset the switch backto the no the flow being monitored pushes against the paddlesystem, the paddle swings away.

2 This changesthe positionof the magnet (2) in relation to the reed contact (3) and thusactivates the soon as the flow is interrupted, the paddle moves back toits starting position, thus activating the reed contact onceagain. The force necessary to push the magnet back isprovided by the two magnets repelling magnetic force instead of the usual leaf spring meansthat the switch is considerably more stable in the long termand much less sensitive to pressure thatconvince Adjustable switching point Low pressure drop Instant response High repeatability Can be used for liquids and gases Switching function dependent on flow rate alone.

3 Not ontemperature or pressureThe reed contact used as a sensing element consists oftwoferro-magnetic contact blades located in a glass bulb filledwith inert gas. This practically eliminates wear resultingfrom contact burning. This construction allowsa useful lifeof up to100000000 switching settings are: contact closes when liquid is flowing contact opens if flow is interruptedThese settings can be changed by the customer can also adjust the switch point setting within thespecified Specific set point adjustment, including special set points Optical flow indicator.
