Introduction

• For many valve automation applications, remote
  indication of the valve position is required.
  Remote valve position is typically achieved
  through the use of mechanical limit switches
  which are usually fitted within an enclosure (a
  switchbox) for use in hazardous locations and to
  provide mechanical protection. Bettis provides
  one main type of switchbox BettiSwitch IITM.
• BettiSwitch IITM switchboxes are typically used
  in applications where explosion proof electrical
  equipment is required.

5
Features Benefits

• Terminal wire strips
• Up to 20 points are available. Terminals are
  rugged, easy to use and are well defined to
  assist technicians
• Epoxy coating
• A long cure, two part epoxy coating provides an
  excellent corrosion resistant exterior to protect
  against aggressive environments. Commando coating
  also available on request
• Rugged aluminium enclosure

6
Features Benefits

• Unique split shaft design
• The split shaft design allows the cover and
  visual indicator to be removed as a complete unit
  with the captive stainless steel screws and
  replaced in its original position for easy
  re-assembly.
• Seals
• The BettiSwitchTM has two o-ring seals, one for
  the shaft and one for the lid (instead of
  unreliable face seals) ensuring that it is
  suitable for use in humid environments
• Easy accessible grounding screws

7
Features Benefits

• Versatile range of switch options
• The interior of the housing is designed to accept
  a large selection of switch designs including the
  Bettis i-max hermetically sealed read switch,
  plus other control accessories. Up to 4 switches
  can be installed
• NAMUR (VDE/VDI) mounting platform
• The BettiSwitch IITM mounting platform is
  machined to provide accurate repeatable shaft
  alignment that fabricated sheet metal brackets
  cannot achieve. The mounting platform is fully
  enclosed for personal protection

8
Features Benefits

• Remote Position Indication
• The Bettis switchbox contains your selection of
  up to four switches to electrically or
  pneumatically provide accurate, positive remote
  feedback of the valve or damper position
• Rugged Corrosion Resistant
• The Bettis switch bases are manufactured from
  Zytel and the beacon indicators from Lexan to
  provide superior strength and resistance to
  corrosive environments
• Junction Box Functionality
• With up to three conduit entries and multiple
  internal terminal strips, the BettiSwitch IITM
  allows solenoid valves, limit switches and other
  feedback devices to be terminated in one single
  enclosure

9
Features Benefits

• Kwik Set Cams
• permit easy and accurate positioning of the limit
  switch trigger points. A splined gear prevents
  slippage caused by vibration or corrosion.

• Cam Adjustment
• Lift cam clear of spline
• Turn cam to adjust
• Push can back onto spline

Features Benefits

• Visual Position Indicator
• The visual indicator is the largest, most easily
  seen indicator on the market. Protected by a
  strong Lexan cover, accurate position indication
  can be seen from almost any angle. Through design
  the overall envelope dimensions of the Bettis are
  smaller than most other designs, even though the
  visual indicator is significantly larger
• Visual Position Indicator Options
• 0º to 90º and 0º to 180º types are available in
  various colors and languages.

11
Features Benefits

• User Friendly
• To facilitate ease of wiring, the terminal strips
  and which module are easily removed from the
  base. Access to the switchbox internals is quick
  and easy a quick turn of the Lexan cover with
  its o-ring sealed bayonet lock to the housing
  completely opens the large working area of the
  switchbox. The Bettis has no external moving parts
