XZS Zero Speed Switch for Hazardous Locations

PROTECT YOUR EQUIPMENT WITH TORQ SPEED SWITCH
ZERO SPEED MODELS FOR HAZARDOUS LOCATIONS

The TORQ Speedetex® XZS Zero Speed Switch is used in bulk material handling/processing systems to monitor speeds of belt conveyors, screw conveyors, bucket elevators, rotary feeder shafts, rotating drums and other types of rotating machinery to protect elevators, feeders and conveyors from speed related damage resulting from broken belts, overloads, or belt slippages. The XZS switch can monitor material flow by sequencing operation of multiple conveyors feeding a common bin or conveyor.

XES Speed Switch for hazardous locations

SPEED SWITCH APPLICATIONS:

  • Bucket Elevators
  • Bulk material handling
  • Chemical processing
  • Coal handling/preparation/storage
  • Conveyor systems (all types)
  • Food processing
  • Foundries
  • Grain processing/storage
  • Mining Equipment
  • OEM applications
  • Paper Manufacturing
  • Plastics Industries
  • Power Plants
  • Rotary Airlocks
  • Saw Mills
  • Steel Mills
  • Special machinery

 

SPEED SWITCH FEATURES:

    • Threaded enclosure provides total environmental suitability for use indoors or outdoors in hazardous, non-hazardous, and wet or dusty industrial environments, as well as protection from falling materials

    • Integral cast mounting feet and 1" conduit opening allow ease and flexibility of installation

    • Threaded cover permits convenient access to interior for ease of installation, calibration, and maintenance

    • Ramped cover ears enable easy bar loosening but not overtightening

    • Neoprene o-ring gasket provides water tightness, and helps prevent the cover from vibrating loose

    • Sealed shaft bearings are lifetime lubricated for long reliable performance

SWITCH OPERATION:

The output logic is selectable to be "on" or "off" in the alarm mode as set by the user. If set for zero speed "on" at start up, there will be an 8 second pre-start delay before the switch operates, to allow for equipment start up. If the pre-start delay time is exceeded before 1.1 RPM (1.2 RPM @ 1/60 turn response option) is reached, the unit will go into alarm mode. The relay will de-energize and the N.C. contacts will be closed. This will also occur at a power failure.

If the output logic is selected "off" the relay will energize, and teh N.C. contacts will open until 1 RPM is exceeded. This condition will remain until the speed of the XZS drops below .9 RPM, (.8 RPM @ 1/60 turn response option) when the N.C. contacts will open.

Options available are 1/60 turn response and supply voltages.
