KG, specifically designed for different thread types and connection standards.
The range includes thread adapters, reducing pieces, transition fittings and swivel adapters that ensure a tight, mechanically stable and standards-compliant connection between pressure gauge, diaphragm seal and process connection. Different thread sizes, standards and installation situations can be flexibly compensated using the appropriate accessories.
Accessories from Armaturenfabrik Franz Schneider GmbH + Co. KG are primarily used in industrial applications where high requirements for pressure resistance, tightness and long-term stability apply. The components are suitable for use with gaseous and liquid media and support the professional installation of pressure measuring instruments in almost any mounting position.
Frequently Asked Questions about AS-Schneider Accessories for Pressure Gauges / Diaphragm Seals / Transmitters / Sensors / Thread Types
What are accessories for pressure gauges and diaphragm seals used for?
Accessories are used to safely connect pressure gauges and diaphragm seals to the process connection, to compensate for different thread types or to correctly align the installation position of the instrument.
Which types of accessories are included in this category?
This category includes thread adapters, reducing pieces, transition fittings and swivel adapters for pressure gauges and diaphragm seals.
Why are thread types important in pressure measurement?
The thread type determines whether a mechanical connection is possible, how sealing is achieved and whether a safe, leak-free installation can be ensured.
Which thread standards are commonly used for pressure gauges?
In practice, BSPP threads such as G 1/4 or G 1/2 and NPT threads such as 1/4″ NPT or 1/2″ NPT are most commonly used.
What is the difference between BSPP and NPT threads?
BSPP threads are parallel and usually seal via a flat gasket or O-ring. NPT threads are tapered and seal via the thread flanks in combination with sealing compounds.
When is a thread adapter required?
A thread adapter is required when the pressure gauge and the process connection have different thread types or thread sizes.
What are reducing pieces used for?
Reducing pieces allow a pressure gauge with a smaller thread to be connected to a larger process connection or vice versa.
What is a pressure gauge swivel adapter?
A swivel adapter allows the pressure gauge to be aligned after installation without loosening the threaded connection or affecting the seal.
When is a swivel adapter particularly useful?
Swivel adapters are especially useful in confined installation spaces or when the pressure gauge must be precisely aligned for easy reading.
Are the accessories suitable for high pressures?
Accessories from Armaturenfabrik Franz Schneider GmbH + Co. KG are designed for industrial applications and are suitable for high pressures and demanding operating conditions.
Can the accessories be combined with diaphragm seals?
The accessories are designed for use with pressure gauges and diaphragm seals and enable a safe connection between both components.
Which materials are used for the accessories?
Typical materials include stainless steel and other metallic materials that offer high mechanical strength and resistance to media.
What role does sealing play in threaded connections?
The seal ensures that the connection remains permanently tight and prevents leakage between the measuring instrument and the process connection.
Can BSPP and NPT threads be connected directly?
Different thread standards should not be connected directly. In such cases, a suitable transition adapter is always required.
For which media are the accessories suitable?
Depending on the design, the accessories can be used for gaseous and liquid media. Media compatibility depends on the selected material and sealing type.
Are the accessories standardized?
Many accessories are based on common DIN standards and international thread standards to ensure interchangeability and safety.
Can accessories be added or replaced later?
Accessories can usually be installed or replaced later, for example during maintenance, retrofitting or instrument replacement.
What are the advantages of high-quality accessories?
High-quality accessories provide better sealing performance, longer service life and a safe, professional installation of pressure measuring instruments.
How do I find the right accessories for my pressure gauge?
The key factors are thread type, thread size, pressure range, medium and installation conditions. If in doubt, technical advice is recommended.
For which applications are AS-Schneider accessories particularly suitable?
The accessories are particularly suitable for industrial applications with high requirements for safety, reliability and measurement stability.
