Differential pressure gauge
Description
These differential pressure gauges are made of highly corrosion-resistant stainless steel. A high overload safety is achieved by the all-metal construction and the close-fitting design of the diaphragm measuring element.
The use of high-quality stainless steel materials and the robust design are geared to applications in the chemical and process engineering industries. Thus the instrument is suitable for liquid and gaseous media, also in aggressive environments.
For further approvals, see page 8
Differential pressure gauge model 732.14
The wetted parts for these instruments are also available in special materials such as Monel or Hastelloy.
Scale ranges of 0 ... 60 mbar to 0 ... 40 bar [0 ... 0.87 to 0 ... 580 psi] ensure the measuring ranges required for a wide variety of applications.
The QR code on the dial allows instrument-specific information such as the serial number, the order number, certificates and other product data to be retrieved from the internet easily and in the long term.
Special features
- Differential pressure measuring ranges from -1 … +30 bar [-14.5 ... 435 psi] to 0 ... 40 bar [0 ... 580 psi]
- High working pressure (static pressure) and high overload safety, selectable 40 bar [580 psi], 100 bar [1,450 psi], 250 bar [3,625 psi], 400 bar [5,800 psi] and 650 bar [9,425 psi]
- The transmission fluid in the measuring chamber dampens the indicator in case of high changes of the rate of pressure
- Model 76x.14: Monel version
- QR code on dial links to instrument-specific information
