Switch with an enclosure that meets nema 4x provides protection from dirt washdowns and corrosive liquids.
Paddle flow switch operation.
Paddle flow switches or vane sensors with an electrical contact output are at a specific flow rate.
Switch with a 316 stainless steel body is more corrosion resistant than switches with a brass body.
Operation is simple and dependable.
Gems sensors offers a broad range of flow switch configurations for use in liquids or gases that feature high quality corrosion resistant materials for use in tough environments with material choices ranging from stainless steel to ryton for vast chemical compatibility.
When flow stops the vane spring moves the vane actuating a single pole double throw switch rated 5a 120 250 vac to start or stop motor pump engine etc.
As flow occurs and the paddle is thrusted forward 20bc 30 c or more the paddle will push the magnet upward and actuate the switch closing the circuit.
Applications include proof of boiler flow air conditioning controlling of dampers according to flow and protecting pumps motors and other equipment against low or no flow.
R1 bspt 1 npt pipe sizes.
Flow switches are mechanical devices used in controlling the flow of air steam or liquid.
Malema flow switches are used in many applications for gases and liquids.
Malema s application engineers are well trained and are ready to assist with custom calibration and sizing to deliver a flow switch that precisely suits your application.
Spdt microswitch mains rated 120 240vac adjustable range.
1 2 3 6 output.
When the liquid is static or nonexistent the spring is fully extended pulling the magnet downward and opening the switch.
Paddle flow switches are for flow no flow detection in large line sizes engineered for positive liquid flow detection at pressures up to 2000 psig 138 bar unique patented cam design assures low pressure drop and does not require bellows seals or mechanical linkages.
In the presence of fluid flow controlled movement of the piston actuates an external hermetically sealed reed switch this switch can be used to actuate audible or visual alarms as well as relays or other controls.
Up to 11bar both fs8 w fs8 wj are stocked parts.
A flow switch operates by conveying a trip motion relay reed switch paddle to another machine within the system usually a pump.
Dwyer flow switches are economical and reliable.
Flow switch operating principle is based on a free floating magnetic piston which responds only to the motion of fluids within the line not to static or system pressures.
0 107 c pressure.
Flow switches are used to determine if the flow rate of a fluid is above or below a certain a set point which can be fixed or adjustable.
The trip signal will indicate to the pump to turn on or turn off.
The flow rate varies based on the pipe size and paddle used.
In most applications the switch is normally off while there is sufficient flow of liquid or air.
Flow switch can detect liquid movement in pipes.
Refer manual for flow setting vs pipe size paddle length process connection.
