from solid material, conical, for flange mounting

Dimension drawing RMR-4F

Dimension drawing · dimensions in mm · binding dimensions per order confirmation

Flanged thermowell from drilled solid material with a conically tapering tip. The most load-resistant design with a flange connection – with an ECTFE, PFA or tantalum coating on request. Dimensions to DIN 43772.

  • Steam, gas and high flow velocities
  • Chemically aggressive media (with coating)
  • Replacement for existing Schramm thermowells SR41
  • Drilled from solid – highest strength
  • Length 200 / 260 / 410 mm, tip Ø 9 – 15 mm
  • Flange DN 25 – DN 50 to DIN EN 1092-1
  • Coating in ECTFE (Halar), PFA or tantalum
