Description

The diaphragm pressure gauge is more suitable for the low pressure range. The small pressure range can be reliably measured by a large working surface of the graphical corrugated diaphragm element. The Model A45 diaphragm pressure gauge conforms to the EN 837-3 standard. High-quality designs are particularly suitable for the chemical and petrochemical industries, the oil and gas industries, and energy engineering. The stainless steel gauge and liquid parts can meet the high requirements of antisive value. For particularly high corrosion resistance requirements, the pressure cavity of the diaphragm pressure gauge can be designed with a variety of special materials (such as PTFE, tantalum or Harbin). For the measurement of high viscosity, crystallization or variable pollution media, it is recommended to use open connection. Compared with the advantage is that the advantage will not block the pressure port through the additional port on the open connection, which can easily clean the pressure cavity. The measuring system with diaphragm elements, based on the design concept that the diaphragm can be supported on the upper flange, can provide good overpressure protection, as the standard, the model A41 gap pressure gauge can achieve overload safety of 5 times the full mileage value, as an option, can achieve higher overload safety.
