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.

Monocrystalline silicon sensors have become the core sensing component of high-end industrial precision instruments, pressure transmitters, and laboratory measurement equipment, gradually replacing traditional polycrystalline silicon and metal strain sensors.

Differential pressure (DP) flow meters are the most widely used flow measurement devices in process industries, relying on pressure difference changes to calculate fluid flow velocity and cumulative flow.

Accuracy class is the core technical indicator determining the measurement performance and application value of pressure transmitters. Common industrial accuracy grades include 0.04%, 0.05%, 0.075%, and 0.1% full-scale error, each matching distinct industrial scenarios, precision requirements and budget standards.
