With the localization rate of nuclear power equipment exceeding 90%, where are the opportunities for domestically produced monocrystalline silicon pressure transmitters?

From “Basic Measurement” to “Intelligent Digital Sensing Terminal”: The Intelligent Upgrade Path of Pressure Transmitters

Hydrogen media features low density, strong permeability and wide‑range working condition fluctuation, bringing severe technical challenges to flow measurement for electrolysis equipment, high‑pressure storage tanks and hydrogen pipeline systems.

Chemical processing plants involve flammable gases, volatile liquids and explosive dust environments, where all electrical instruments must comply with strict explosion protection standards to eliminate ignition risks.

Pressure transmitters are core measuring devices for industrial process control, with monocrystalline silicon, diffused silicon, and ceramic capacitor sensors dominating mainstream industrial applications.

Small flow rate measurement is a long-standing technical difficulty in industrial process monitoring, as tiny fluid pressure changes are easily submerged in sensor noise, drift and mechanical hysteresis errors.

Differential pressure (DP) flow meters are foundational to industrial flow measurement, widely used for gas, liquid, and steam monitoring across petrochemical, power, and process manufacturing industries. Unlike direct-reading flow devices, DP systems calculate flow based on the square root of differential pressure signals, a nonlinear principle that exponentially amplifies minor transmitter errors into significant flow deviations, especially under low-flow conditions.

Industrial field environments often involve drastic temperature fluctuations, covering ultra-low cold conditions of -40℃ in winter outdoor installations and high-temperature heat radiation up to 85℃ in summer factory workshops

High-end precision instruments for industrial measurement and laboratory testing demand exceptional accuracy, repeatability, and long-term operational stability under complex working conditions. Monocrystalline silicon sensors have gradually replaced traditional metal strain and polycrystalline silicon sensors to become the core sensing component of premium industrial instruments.
