W7 PLc Diathermic oil FDA – Voltage output – PLc

W7 PLc


  • The W7 Performance Level ‘c’ Series are pressure sensors for use in high-temperature applications where the process temperatures may reach 315°C (600°F) such as high-temperature engineered polymers.
  • The W Series utilizes standard melt pressure principles and construction; strain sensing technology is bonded foil strain gauge.
  • A near incompressible mixture (diathermic oil) is used for pressure transmission.
