描述

Features

  • Reduce field failures
    – Excellent tolerance to overpressure & vibration reduces field failures
  • Reduce setup
    – Selectable ranges and scales reduce setup time and number of models to stock
  • High accuracy
    – High accuracy digital sensor with seven selectable sub-ranges maintains calibration and reduces callbacks
  • Water-resistant housing
    – IP65/NEMA 4 housing allows for mounting in wash-down locations
  • Maintenance free
    – High reliability sensor technology for long-term, maintenance-free operation
  • Circuit protection
    – Circuit protection avoids damage due to incorrect input wiring

Applications

  • The P7650 sensor can measure either air pressure or velocity. Measuring air velocity requires the use of the P7650L velocity pick-up probe. The P7650 is available in three installation configurations: duct, panel or universal. Duct and panel models have two pressure and velocity options: 0-1” WC / 0-3,000 FPM or 1-10” WC / 3,000- 6,000 FPM with four field-selectable sub-ranges.
    The universal model comes in one pressure/velocity range: 0-10” WC / 0-7,000 FPM with seven field selectable sub-ranges. All variants are available with and without display. The P7650 has an IP65/NEMA 4 environmental rating.
  • Duct static pressure (Pressure mode)
  • Building or room pressure (Pressure mode)
  • Filter status (Pressure mode)
  • Air flow measurement (Velocity mode)
