Description of DWYER PG

Application flexibility is assured by a large variety of switching options including SPST, SPDT, DPST and DPDT; opening or closing on increasing pressure, vacuum or differential. PR and PRL models add manual reset operation on increasing or decreasing pressure. Mercury switches or hermetically sealed snap switches are available where high humidity would be a problem. If vibration or other factors preclude the use of mercury, snap switches can be provided. Standard housing is NEMA 1. Optional enclosures can be supplied for weather resistant requirements.

PRODUCT APPLICATIONS

  • Natural, manufactured or LP gas applications

FEATURES

  • Clear easy-to-read scale and external set point adjustment simplifies operation and trouble shooting
  • Large diaphragm provides accuracy for precise control
  • Multiple switching options meet the design of applications
