APPLICATIONS
High level ***ector in bins and vessels containing a wide variety of materials.
Chute or transfer point plug-up ***ector.
Conveyor belt misalignment ***ector.
Level control in volumetric batching.
Crash probe for tripper car.
Starvation or no-flow ***ector for belt and vibratory feeders.
The Pro-Line tilt switch is actuated when material rises to tilt the probe 15 degrees or more from its vertical position.
The mercury switch is precisely positioned so that, regardless of direction of tilt, the normally-closed contacts are caused to open. The switches are encapsulated in various sizes to suit the application.
The Model 20-43 control unit is housed in a NEMA 4X box with green ("Normal") and red ("Alarm") indicating lights inside a clear front enclosure.
A 0-10 second adjustable time delay circuit in the control unit prevents momentary tilting of the switch from causing a false or premature contact transfer. An internal jump wire permits selection of "Normal" condition either with the tilt switch vertical or tilted. Two normallyopen and two normally-closed output contacts are available for connection to external alarms and/or controls.
Interruption of line power causes a relay transfer.
Various probe assemblies are available for application with a wide variety of materials and environmental conditions
The control unit is also available without enclosure for mounting in other types of enclosures and control panels
