Diaphragm pressure gauge, Model 432.50, 0-4 bar
wikaDescription
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.
The diaphragm pressure gauges 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.
Measuring systems with diaphragm elements, on the
grounds of their design, offer good protection from overload,
since the diaphragm can support itself against the upper
flange. As standard, this diaphragm pressure gauge already
features an overload safety of 5 times the full scale value.
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.
