A diaphragm seal with threaded connection pressure gauge is designed to measure pressure in challenging process conditions.
It protects the pressure gauge from corrosive, viscous, or contaminated media.
The flexible diaphragm isolates the measuring element from the process fluid.
Pressure is transmitted through a fill fluid to ensure accurate readings.
The threaded connection allows easy and secure installation into pipelines or equipment.
Common thread types include BSP, NPT, or metric threads.
It is widely used in chemical, oil, gas, and water treatment industries.
The design prevents clogging and damage to the internal components of the gauge.
Diaphragm materials can be selected based on process compatibility, such as stainless steel or PTFE.
It is suitable for applications with limited space due to its compact design.
The unit can handle moderate to high pressure and temperature conditions.
It improves the reliability and lifespan of the pressure gauge.
The assembly may be directly mounted or connected via a capillary for remote reading.
It ensures stable performance even under vibration and pressure fluctuations.
Overall, it provides safe, efficient, and accurate pressure measurement in industrial systems.
A threaded diaphragm seal pressure gauge protects measuring instruments from corrosive, hot, or viscous media by using a flexible metal membrane to separate the process fluid from the gauge. Featuring a threaded process connection (e.g., NPT, BSP) and a filled capillary or direct mount, it is ideal for high-pressure industrial applications up to 1, 000 bar
