Diaphragm seal and capillary manufacturing, and repair services
Manufacturing of diaphragm seals and capillaries, and oil filling for use in pressure and differential pressure transmitters, switches, and pressure gauges, along with instrument coupling.
Manufacturing of diaphragm seals with the following specifications:
Available diaphragm seal models: Flanged (Flush, Wafer) and threaded.
Diaphragm part materials: SS316L, PTFE
Capillary length: up to 6 meters
When the process fluid enters the capsule, it applies pressure to the capsule walls, causing deformation of the diaphragm walls.
Capsules can also be arranged sequentially in line, thereby increasing the resulting displacement.
For this reason, in many cases, a capsule containing two connected metal diaphragms is used.
This capsule is connected to the measured fluid through a tube.
When the process fluid enters the capsule, it applies pressure to the capsule walls, causing deformation of the diaphragm walls.
Capsules can also be arranged sequentially in line, thereby increasing the resulting displacement.
Compared to Bourdon sensors, diaphragm sensors, having a larger support surface, are less sensitive to environmental vibrations.
These sensors are also widely used for measuring the pressure of viscous fluids.
It is worth noting that a major drawback of diaphragms is zero-point adjustment.
Calibration certificates can be provided by accredited institutions under the supervision of the national standards authority within a minimal timeframe.
