Core Features and Advantages
🛡️
Corrosion and Clogging Prevention
The diaphragm completely isolates the measured medium from the internal components of the pressure gauge, preventing corrosive media from damaging the instrument and preventing viscous or particulate media from clogging the instrument channels.
🎯
Reliable Measurement Accuracy
Low pressure transmission loss of the sealing fluid, combined with a high-precision gauge head, enables accurate pressure measurement, typically achieving accuracy classes of 1.0 or 1.6.
⚙️
Adaptable to Complex Operating Conditions
Can operate in high and low temperature environments (compatible with different types of sealing fluids and diaphragm materials); some models can also be used for vacuum pressure measurement.
🔧
Flexible and Diverse Installation
Supports multiple installation methods including threaded connections, flange connections, and sanitary clamp connections (suitable for the food and pharmaceutical industries), adapting to different process pipelines.
Frequently Asked Questions
❓ What is the purpose of the diaphragm in a diaphragm pressure gauge?
The diaphragm acts as a physical barrier that completely isolates the measured medium from the internal components of the gauge. This prevents corrosive, viscous, or particle-laden media from damaging or clogging the instrument, ensuring long-term reliability and accurate readings.
❓ What accuracy class does this pressure gauge achieve?
This diaphragm pressure gauge typically achieves accuracy classes of 1.0 or 1.6, thanks to the low pressure transmission loss of the sealing fluid combined with a high-precision gauge head.
❓ What thread types and sizes are available for connection?
The gauge supports a wide range of thread types and sizes including 1/8", 1/4", 3/8", and 1/2", with thread standards such as PT (BSPT, ZG), BSP (G, PF), and NPT, making it compatible with most industrial process pipelines worldwide.
❓ Is this gauge suitable for use in the food and pharmaceutical industries?
Yes. The gauge supports sanitary clamp connections in addition to threaded and flange connections, making it well-suited for food and pharmaceutical applications where strict hygiene requirements must be met, such as measuring the pressure of sauces, dairy products, and pharmaceutical solutions.
❓ Can this pressure gauge be used in extreme temperature environments?
Yes. The gauge is designed to operate in both high and low temperature environments. By selecting compatible sealing fluids and diaphragm materials appropriate for the specific temperature range, the instrument can maintain reliable performance under demanding thermal conditions.
❓ What materials are used in the construction of this pressure gauge?
The key components are made from stainless steel, including the case, ring (cover), connection, Bourdon tube element, and movement. The dial plate is white aluminum with black graduations, the window is glass, and the pointer is made from black-finished aluminum alloy — ensuring both durability and clear readability.
