Purchasing Guide

Based on real user feedback, we provide the following suggestions:

  • When selecting a micro differential pressure transmitter, it is recommended to prioritize confirming key parameters such as range (e.g. 0-500Pa) and accuracy level (e.g. ± 0.5% FS) to ensure compatibility with specific scenario requirements such as HVAC or cleanroom differential pressure monitoring.
  • When selecting suppliers, reference can be made to indicators such as product compatibility, business qualifications, enterprise activity, industry performance, and industry data support. For example, suppliers who have served pharmaceutical factories or laboratories for a long time usually have more stable performance verification records.
  • For high-frequency application scenarios such as air duct pressure difference monitoring or filter blockage alarm, attention should be paid to the long-term stability and anti-interference ability of the transmitter. It is recommended to choose products with temperature compensation and overvoltage protection functions.
  • Micro differential pressure transmitters used in industrial environments need to consider protection levels (such as IP65) and medium compatibility. Practical application cases of suppliers in the petrochemical or semiconductor industries can serve as important reference.
