Frequently Asked Questions
Q
What is the main purpose of the diaphragm in a diaphragm pressure gauge?
The diaphragm acts as a physical barrier between the measured medium and the gauge's internal components. It prevents corrosive, viscous, or particle-laden media from entering and damaging the Bourdon tube, movement, and other sensitive parts, thereby extending the service life and maintaining measurement accuracy.
Q
What thread standards are available for this pressure gauge?
This gauge supports a wide range of thread standards to suit different regional and industry requirements, including PT (BSPT/ZG), BSP (G/PF), and NPT, in sizes 1/8", 1/4", 3/8", and 1/2". Please specify your required thread type when ordering.
Q
What accuracy class does this pressure gauge achieve?
Thanks to the low-loss sealing fluid transmission system and high-precision gauge head, this diaphragm pressure gauge typically achieves accuracy classes of 1.0 or 1.6, making it suitable for most industrial measurement applications that require reliable and consistent readings.
Q
Is this gauge suitable for use in the food and pharmaceutical industries?
Yes. The gauge supports sanitary clamp connections and is compatible with materials that meet hygiene standards. It is well-suited for measuring the pressure of viscous or hygiene-sensitive media such as dairy products, sauces, and pharmaceutical solutions where contamination must be strictly avoided.
Q
Can this pressure gauge be used for vacuum pressure measurement?
Yes, certain models of this diaphragm pressure gauge are designed to handle vacuum pressure measurement. The specific capability depends on the selected diaphragm material and sealing fluid. Please consult our technical team to confirm suitability for your specific vacuum application.
Q
What materials are used in the construction of this gauge, and why does it matter?
The case, ring, connection, Bourdon tube (element), and movement are all made of stainless steel, providing excellent corrosion resistance and mechanical durability. The aluminum alloy pointer with black finish ensures clear readability, while the white aluminum dial plate with black graduations offers high contrast for easy on-site reading in various lighting conditions.
