AFRISO Data sheet Standard Bourdon tube pressure gauges for refrigeration engineering type D7 with glycerine filling

Benefits

  • Can be used in case of heavy vibrations and high, dynamic pressure loads
  • Longer service life due to less wear and corrosion protection of the measuring system
  • Various refrigerants measurable with multiple scales
  • DNV- and GOSSTANDART-certified

Application

For simultaneous measurement of vapour pressures and temperatures in refrigeration engineering.

! For measuring gas or vapour, observe the table "Selection Criteria as per EN 837-2" (see appendix)!
