A "sealed pressure transmitter" usually refers to a diaphragm-sealed pressure transmitter, which is a special type of pressure transmitter designed to address the measurement challenges in harsh working conditions.

• Isolated Measurement:

  The transmitter body does not come into direct contact with the medium, allowing for the measurement of highly corrosive, high-viscosity, easily crystallizing, and solid-particle-containing media, as well as high-temperature melts.

• Flexible Structure:

  The single-flange or double-flange structure can be selected based on installation requirements. The double-flange is commonly used for liquid level, density, or interface measurement. .

• Stable performance:

  It adopts advanced sensor technology (such as single crystal silicon resonant type), featuring high precision, high stability, rapid response and self-diagnosis function.

• Convenient installation:

  The length of the capillary can be customized according to the on-site distance, making it easy to install the transmitter in a position that is convenient for observation and maintenance, away from high-temperature or vibration sources.

• Reliable protection:

  It has good sealing performance by itself, and with the appropriate protection grade, it can adapt to harsh on-site environments.

• Chemical and Petrochemical:

  Measuring highly corrosive liquids such as hydrochloric acid, sulfuric acid, caustic soda, as well as high-viscosity media like crude oil, residual oil, and asphalt.

• Pharmaceutical and Food & Beverage:

  In sanitary processes, measuring fermentation broth, syrup, chocolate, milk, etc., with requirements for no residue and easy cleaning, often using sanitary clamp connections.

• Power and Energy:

  Used for measuring the water level in boiler drums and deaerators, as well as the pressure of high-temperature steam and condensate, often equipped with high-temperature isolation diaphragms and filling fluids.

• Papermaking and Chemical Fibers:

  Measuring pulp, black liquor, chemical fiber slurry, and other liquids containing fibers or prone to crystallization.

• Water Treatment and Environmental Protection:

  Monitoring media such as sewage, sludge, and chemical solutions.

Diaphragm-sealed pressure transmitters are professional solutions for pressure measurement in complex working conditions such as corrosive, high-temperature, high-viscosity, and easily crystallizable environments. Their core value lies in the isolation transfer technology achieved through isolation diaphragms and capillaries, which effectively protects the precise sensors and ensures the long-term stability and reliability of the measurement.
