Silver Series with Latching Reed Switch
Latching Reed Switch
Latching Reed Switch alarm available for the Silver Series
The latching reed switch is an available option for the Silver Series Flowmeter.
The switch assembly is mounted on the side of the metering tube by a dovetail or guide rod. The switch can be positioned to trip at any point on the scale.
The switch is a reed type and uses a biassing magnet to give it the latching feature. The float contains hermetically sealed magnet(s), so when the float comes in close proximity to the switch it closes and remains closed (latched) when the float moves below the switch it resets itself. Multiple switches can be used.
Operating temperature range is -40° C to 125° C.
