Diaphragm pressure gauge for the process industry, Model 432.56, 432.36

Applications

• For measuring locations with increased overload
• For gaseous, liquid and aggressive media, also in aggressive environments
• With open connecting flange also suitable for contaminated and viscous media
• Process industry: Chemical industry, petrochemical industry, power plants, mining, on-/offshore, environmental technology, machine building and general plant construction

Special Features

• High overload safety, optionally 40, 100 or 400 bar due to the metallic pressure element limit stop, without liquid-filled measuring cell
• Wide choice of special materials
• Compatible with switch contacts
• Case and wetted parts from stainless steel
• Scale ranges from 0 … 16 mbar

Description

Diaphragm pressure gauges are preferably used for low pressure ranges. Through the large working surface of the circular, corrugated diaphragm element, small pressure ranges can be measured reliably.

Depending on the version, the models 432.56 and 432.36 are able, already from the smallest scale range of 0 … 16 mbar, to withstand an overload of 40, 100 or 400 bar without any subsequent impairment of their measurement characteristics.

The diaphragm pressure gauge models 432.56 and 432.36 are manufactured in accordance with EN 837-3. The high-quality design is particularly suitable for applications in the chemical and petrochemical industry, oil and gas industry and power engineering.

The case and wetted parts from stainless steel fulfil high requirements for resistance against aggressive media. For especially high resistance requirements, the pressure chamber can be designed with a wide variety of special materials such as PTFE, tantalum or Hastelloy.

For the measurement of highly viscous, crystallising or contaminated media, the use of an open connecting flange is recommended. The open connecting flange has the advantage over a threaded connection that the pressure port cannot become blocked. With an additional flushing bore on the open connecting flange, the pressure chamber can be easily cleaned.
