Considerations when selecting pressure instruments
When selecting pressure instruments, some of the key considerations include:
Compatibility: It is important to ensure that the pressure instrument is compatible with the specific process conditions, such as pressure range, temperature, and media being measured.
Accuracy: The accuracy of the pressure instrument should be sufficient for the intended application.
Durability: The pressure instrument should be able to withstand the harsh conditions of the process and have a long service life.
Display and readability: The instrument should have a clear and easy-to-read display, with large digits and contrasting background.
Calibration and maintenance: The pressure instrument should be easy to calibrate and maintain.
Safety: The pressure instrument should be designed to minimize the risk of leakage, explosion or other safety hazards.
Certifications: It is important to ensure that the instrument is certified for use in the specific industry or application.
Cost: The cost of the pressure instrument should be considered in relation to the benefits it provides.
Support and service: The supplier of the pressure instrument should provide adequate support and service, including training, calibration and repair.
Environmental factors: The pressure instrument should be able to withstand the environmental factors, such as vibration, shock, and EMI/RFI.
What Are the Best Pressure Gauges for Ammonia Plant Applications?
For ammonia plant applications, it is recommended to use pressure gauges that are specifically designed for use with ammonia. These gauges should be made of materials that are resistant to corrosion from ammonia, such as stainless steel or Monel. They should also have a high pressure rating and be able to withstand extreme temperatures. Additionally, it is important to ensure that the gauges are compatible with the specific process conditions in the ammonia plant, such as high pressure and high flow rates. Some of the reputable manufacturers for pressure gauge for ammonia plant application are WIKA, Ashcroft, and WESEN.
