762.14 WIKA differential industrial pressure gauge

Description

The 762.14 WIKA industrial differential pressure gauge with high load safety up to 40, 100 or 400 bar is used for measuring pressure differentials of gaseous and liquid media.

These differential pressure gauges are made of corrosion-resistant stainless steel. High safety over pressure is achieved by the metal construction and the tight-fitting pressure measuring diaphragm.

With its high-quality stainless steel construction and robust design, this pressure gauge is adapted to chemical and process engineering.

The wetted parts of these instruments are also available in special materials such as Monel or Hastelloy.

Scale ranges from 0 … 60 mbar to 0 … 40 bar provide the measuring ranges required for a wide variety of applications.

 

Features 762.14

• Design:

  differential pressure gauge to DIN 16003, maximum overload protection on both sides, nominal values PN 40, 100, 250 or 400. The transfer fluid in the measuring chamber dampens the indicator in the event of large changes in the pressure level.

  • Instruments with PN 40 and 100:
    • 0… 60 mbar to 0… 160 mbar (measuring chamber □ 140)
    • 0… 0.25 bar to 0… 40 bar (measuring chamber □ 82)
  • Instruments with PN 250:
    • 0… 60 mbar to 0… 250 mbar (measuring chamber □ 140)
