The PW30 Series uses remote sensors to eliminate the need for costly bypass assemblies, enabling fast, cost effective installation. The remote sensors mount directly to pipe to eliminate bleeding and additional plumbing. Optional factory pre-wired harnesses also available in wire and armored cable versions. NEW! Order pre-fabricated with a 3 or 5-valve bypass assembly for easy bleeding and installation where bypass is required. Standard LCD screen and dip switches make configuration a breeze. Measure 16 differential pressure ranges from 1-500 PSID with a single device without sacrificing accuracy. Selectable output 0-5V, 0-10V, or 2 Wire 4-20mA.

  • Demand measurement in HVAC systems for pump speed control and local indication
  • Process control systems
  • Flow measurement of gases, vapors, and liquids compatible with 316L SS
  • Filter status monitoring
  • System leak detection
  • Great for data center wet pressure sensing

(1) One side of transformer secondary is connected to signal common. Dedicated transformer is recommended.

(2) FS is defined as the full scale of the selected range. Accuracy includes non-linearity, hysteresis, and repeatability.

(3) Because of lower accuracy, it is not factory recommended to use an output range less than 10% of the total sensor PSIG.
