DWYER Photohelic A3000 pressure switch & gage

DWYER Photohelic A3000 pressure switch & gage

The Series A3000 Photohelic® Switch/Gages function as versatile, highly repeatable pressure switches combined with a precise pressure gage employing the time-proven Magnehelic® gage design. The Photohelic® switch/gage measures and controls positive, negative or differential pressures of air and compatible gases. Standard models are rated to 25 psig (1.7 bar) with options to 35 (2.4) or 80 (5.5 bar) psig. Two phototransistor actuated, DPDT relays are included for low/high limit control. Easy to adjust set point indicators are controlled by knobs located on the gage face. Individual set point deadband is one pointer width – less than 1% of full scale. Set points can be interlocked to provide variable deadband – ideal for control of fans, dampers, etc. Gage reading is continuous and unaffected by switch operation, even during loss of electrical power. Choose from full scale pressure ranges from a low 0-.25 in (0-6 mm) w.c. up to 30 psi (21 bar).

NIST CALIBRATION available in Product Configurator

PRODUCT APPLICATIONS

  • Air Conditioning Systems
  • Clean Rooms
  • 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.

OPTIONS

  • -SR Single contact, right set point, for actuation on increasing or decreasing pressure.
  • -OLS OEM Model, less relay and transformer components and housing but including infared diodes and phototransistor(s), light shutter and set pointer(s). For single or double contact.
  • -RMR Remote-Mounted Relay, relay pack may be mounted remotely from gage. Standard length is 5 ft. For other lengths, specify cable length required.
  • -TAMP Tamper-proof knobs, low temperature option, special scales, voltages and other features and modifications are available.
  • Special Housings available include Weatherproof (NEMA 4) and Explosion-proof (NEMA 7 & 9; NEC Cl I, Gr C&D; Cl II, Gr E, F&G; Cl III). Contact Customer Service for detailed dimension drawings.
  • Scale No. 3401 Square Root Specify Range.
  • Scale No. 3402 Blank Scale Specify Range.
  • High & Low Latching Circuits. Dwyer Photohelic® switch/gages can be wired for high-latching, low-latching or combination high-low latching circuits. That is, the equipment will hold in these respective positions once activated and until manually reset. This can be particularly useful for alarm and signal applications where control is accomplished by another Photohelic® switch/gage or other means. Complete wiring and operational instructions are included. Where manual reset is required a dry circuit push button such as Dwyer Part A-601 should be used.
