• Magnetic spring contact switches are available as a factory installed option on 40-400 Series and 40-410 Series
• An excellent choice when an accurate pressure switch is required in addition to a reliable pressure gauge
• Fully adjustable by the user
• These switches are actuated by the pressure gauge pointer to provide accurate field adjustment
• A removable adjustment key makes them tamper-proof
• They operate with an extremely broad power supply, AC or DC up to 250V max. (30W 50 VA), allowing them to be used virtually anywhere in the world in addition to very remote applications with only DC battery pack power available
• Standard units consist of (2) two magnetic spring switches; either one or both switches may be used:
  • Switch (1) one is normally closed
  • Switch (2) two is normally open with operation referenced on clockwise pointer motion
• The lowest full scale pressure range this switch may be used on is 0 psi to 60 psi because of the increased load on the pointer and Bourdon tube
• A mating 4-pin connector with 5' of 4-wire and color coded shielded cable is standard

Applications:

• • Air compressors
  • Gas compressors
  • Hydraulic and pneumatic circuitry
  • Die-cast machinery
  • Plastic injection molding machinery

Wiring and terminal location

• An invaluable tool for identifying pressure spikes in a system
• Extremely helpful during system start up and troubleshooting
• MIPs add an additional ±1% error to the gauge because of the increased load on the Bourdon tube
• On ranges of 60 psi and lower, MIPs may double the allowed error of the gauge

• Needle valves can provide block and bleed function for a pressure sensor in the system
• Good industry practices state that a pressure measurement device should be “blocked in or have a block and bleed feature” for safety and ability to service the instrument
