Pressure - Wet-Wet DP (Conduit Version)

  • Conduit adapter design
  • 0 to 10~500 PSID (switch selectable, ranges vary depending on elements/transmitter selected)
  • Built-in snubbers protect sensing elements from water hammer damage
  • LCD display toggles between Supply,Return and Differential pressure readings
  • Dual 0-5/10VDC and 4-20mA outputs


  • Ideal for monitoring pumps and load differential pressures in HVAC systems and processes where local indication is needed.
  • Process control systems
  • Flow measurement of various gases or liquids
  • Liquid level measurement of pressurized vessels


The PW Conduit Wet-Wet series remote sensors are installed directly into the pipe and electrical connection is made between the PWC remote sensors and PW transmitter via 4-conductor shielded cable run through conduit.  This dramatically reduces labor cost by eliminating plumbing/piping to a traditional transducer. Startup time is reduced since purging air out of the lines is not necessary. Traditional plumbed bypass assemblies are no longer required. Choose between the PW10 and PW20 model based on your anticipated PSID range.

Conduit ports on transmitter and elements

  • Run conduit and 4-conductor shielded cable from transmitter to elements to wire in the field
  • Eliminates costly plumbing and by-pass manifolds

Versatile Universal Transmitter 

  • Three selectable PSID ranges per sensing element
  • Low and standard PSID range transmitter models
  • 500 PSIG is ideal for high rise applications
