Description

Senva’s PW31 Series is designed to streamline installation and provide maximum accuracy. Options for standalone transducer or 3-valve and 5-valve bypass assemblies allow flexibility and save time on installation and commissioning. The single-diaphragm element is temperature compensated to provides superior ±0.25% accuracy. The PW31’s compact, light, and rugged structure combined with IP65 stainless steel construction make it ideal for most installations and capable of withstanding the most rugged environments. Now available with a highly visible, loop-powered LED display. Just plug it in for ease of commissioning and troubleshooting (4-20mA version only).

Applications

  • Meet rigid accuracy and/or bypass specifications
  • Demand measurement in HVAC systems for pump speed control and local indication
  • Process control systems
  • Measurement of gases, vapors, and liquids
  • Measure pressure changes on pumps for efficiency regulation and energy savings
  • Level measurement in tanks and vessels
  • Filter status monitoring
  • System leak detection
  • Great for data center wet pressure sensing
