JSL -1E Wind Indicator Relay

JSL-1E (Plant Engineering)

Mechanically operated, for the monitoring of air flows in ducts, in air supply and air exhausting devices of fans or electrical heat registers.

The wind indicator relay is set to the minimum switching points at the factory. The switch-on/switch-off values can be increased by turning the inner screw clockwise. Fitting is done in the vertical paddle position from the top in a horizontal pipe/duct.

JSF - 1E ... 4E Liquid Flow Monitors

JSF Liquid Flow Monitors (Industrial Technology)
