RAMSEY 20-39 tilt switch

Descripción del producto

****9 tilt switch

Rugged, abrasion-resistant tilt switch.
Simple installation.
Control unit is solid state, printed circuit board construction.
Adjustable time delay to *0 seconds
Prevents false trips.
Control unit standard NEMA 4X
enclosure (Model ****3) or without
enclosure (Model ******1) for control panel mounting.
Performance proven in thousands of applications throughout the world.
All probes include mounting hardware.
APPLICATIONS
High level detector in bins and vessels containing a wide variety of

materials.
Chute or transfer point plug-up detector.

Conveyor belt misalignment detector.
Level control in volumetric batching.
Crash probe for tripper car.
Starvation or no-flow detector for belt and vibratory feeders.
The Pro-Line tilt switch is actuated when material rises to tilt the

probe *5 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 ****3 control unit is housed in a NEMA 4X box with green

("Normal") and red ("Alarm") indicating lights inside a clear front

enclosure.
A ***0 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
