The pressure transmitter converts the physical parameters of gas and liquid sensed by the sensor into standard signals. These physical quantities include pressure, temperature, flow rate, etc. Standard signals will be provided to indicate alarms, recorders, etc. These secondary instruments perform measurement, recording, and process regulation.
Common Thread for Pressure Transmitters
Thread Size | Illustration | Standard | Sealing | Usage |
| M |  | Metric | No sealing property after tightening, the only connection in the pipeline. | Non-pipe connection; Used for low-pressure pipelines(with sealing rings). |
| R |  | Imperial | Sealing after tightening. | Used for pipe connections, such as water pipes, oil pipes and air pipes. |
| G |  | No sealing property after tightening. Used for low-pressure pipelines(with sealing rings). | ||
| NPT |  | American-made | Sealing after tightening. |
In addition to common thread connections, MicroSensor provides clamp and flange connections. For any questions about product selection, please do not hesitate to contact us.
How to Choose the Materials of the Diaphragm and Process Connection Port?
| Material | Applicable Media | Features | Application |
| 316L | Room temperature nitric acid environment with concentration ≤68%; alkaline environment; 10% concentration of sulfur dioxide and hydrogen sulfide environment. | Suitable for water-related media | Water, fire protection, heating, environmental protection and other industries. |
| Titanium alloy | Atmosphere, sea water, nitric acid, sulfuric acid; oxidizing media and strong bases. | Corrosion performance is higher than most 316L materials | Shipping industry |
| Hastelloy C276 | Normal temperature phosphoric acid environment; Various organic acids (except hydrofluoric acid) | Not suitable for the alkaline environment; In environments with high concentrations of nitrates and sulfates | Petroleum and petrochemical, flue gas desulfurization, pulp and paper and other industries |
| Tantalum | Suitable for all media (except hydrofluoric acid and strong alkali) | Extremely high corrosion resistance | Aerospace, medical and scientific research and other fields. |
Economical:
316L>Titanium alloy>Hastelloy C276>Tantalum
Corrosion resistance:
Tantalum＞Hastelloy C276＞Titanium alloy＞316L
The selection of the material of the pressure transmitters interface needs to be combined with a comprehensive evaluation and selection of the diaphragm material and medium characteristics.
