Standard Bourdon tube pressure gauges for refrigeration engineering type D8 with glycerine filling

Data sheet Standard Bourdon tube pressure gauges for refrigeration engineering type D8 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)!
