Model PM-35-N4 & Model PM-75-N4 Pilot Monitors for Non-Hazardous Area Classification Williamson

特徴

The Williamson Pilot Monitor (PM) utilizes proven dual-wavelength technology to sense the presence of the small, distant pilot flame. This technology allows the pilot monitor to view clearly through severe weather conditions caused by fog, wind, rain, snow and sleet.

  • Self-regulating means no on-site calibration
  • May be grade-mounted for easy access
  • 30% greater sensitivity means greater reliability
  • Includes Signal Dilution output for measurement validation and diagnostics
  • Large viewing area for easy alignment
