Indicating Gage, Lo-limit and Hi-limit Control
Photohelic® Pressure Switch/Gage functions as versatile, highly repeatable pressure switch combined with a precise pressure gage. Applications include air conditioning systems, clean rooms, and fume exhaust systems.
 
Features
  • Bezel and front cover (with set point knobs and zero adjustment screw) removed to expose Photohelic® switch/gage set point mechanism. Cover is clear polycarbonate plastic.
  • Gage pointer and light shutter are mounted on helix and balancing counterweight. Shutter passes through slot in optical limit switch to expose phototransistors to integral infrared light source or mask them depending on applied pressure.
  • Light shield effectively protects phototransistors from strong outside light sources yet allows free pointer movement. It also gives interior a clean "finished" look.
  • Optical limit switches are used for reliability and long service life. Attached directly to set pointers, they are individually aligned to assure precise switching accuracy.
  • Semi-Flexible drive shaft connects to set point knobs.
  • Zero adjustment screw connects to screw in cover to adjust zero pressure reading.
  • Plastic enclosure protects electronic components and electrical connections.
  • Polycarbonate connection or terminal board is self-extinguishing.
  • Glass epoxy printed circuit boards for durability and permanence.
  • Load relays are DPDT with latching feature for maximum application versatility.
  • Electronics are designed to operate on 50/60 Hz, 120 volt current with 10% over or under voltage. Special units for other voltages are available.
  • Switch set pointers show switch settings at all times.
  • Spring loaded friction clutch prevents operator damage of set point mechanism.
  • 3-in-1 instrument allows the reduction of several instruments with one product, saving inventory, installation time and money.
  • Patented design and 1% full scale dead band provides quick response to pressure changes means no delay in switching and chatter-free operation.
  • A wide range of models that can meet pressure measurement specifications from low to very high.
Product Applications
  • Air Conditioning Systems
  • Clean Rooms
  • Fume Exhaust Systems
