High-Sensitivity And Stable Differential Pressure Transmitter With Micro Differential Pressure

A micro differential pressure transmitter is a specialized transmitter designed to measure very small pressure differences between two pressure points.

Core Features
  1. High Sensitivity and Accuracy: It can detect extremely small pressure changes (such as the pressure exerted by a single strand of hair on the sensor), thus requiring extremely high manufacturing precision and material quality for the sensor.

  2. Excellent Overpressure Protection: Although it measures minute pressure differences, the static pressure in process pipelines or equipment can be very high (for example, when measuring wind speed in an air duct, the static pressure of the duct itself may be several hundred kPa). The transmitter must be able to withstand high pressure from either end or both ends without damage or drift.

  3. Superior Environmental Interference Resistance:

    • Temperature Impact: Temperature variations can cause deformation of sensor materials and circuit drift, necessitating precise temperature compensation.
    • Vibration Impact: Mechanical vibrations can generate noise signals, requiring a robust structure and damping design.
    • Static Pressure Impact: High static pressure may cause slight deformation of the sensor diaphragm, affecting the zero point and range.
Typical application scenarios (solving what problems)
  1. Filter/carbon filter blockage monitoring (core application):

    • Function: Alarm when the pressure difference reaches the set upper limit, indicating that the filter needs to be cleaned or replaced to ensure system efficiency and equipment safety.
    • Scenarios: HVAC system air filters, engine intake filters, production process fluid filters.
  2. Flow measurement (non-full pipe):

    • Scenarios: Primary/secondary air flow of boilers, flue gas flow rate, supply/return air volume balance in clean rooms, air volume in ventilation ducts.
  3. Liquid level measurement (sealed containers):

    • Principle: For sealed tanks with pressure or inert gas protection, the liquid level height can be calculated by measuring the pressure difference between the bottom and top of the tank and combining it with the medium density.
    • Scenarios: Bioreactors in the pharmaceutical and food industries, pressurized storage tanks.
  4. Monitoring the status of key equipment:

    • Principle: Monitor the pressure drop in key channels.
    • Scenarios: Plate heat exchanger blockage monitoring, radiator air resistance monitoring, pressure difference monitoring between clean rooms and the outside (maintain positive/negative pressure to prevent contamination or leakage).
  5. Combustion control and safety:

    • Principle: Monitor the furnace negative pressure and the pressure difference between primary and secondary air to ensure stable and safe combustion.

The differential pressure transmitter is the "precise sensory nerve" in industrial automation systems, specifically designed to convert minute pressure differential changes into reliable control signals. The core issue it addresses is: in complex and high static pressure industrial environments, accurately and stably monitoring those critical minute pressure differential parameters that characterize equipment health status, process efficiency, and safety, thereby achieving predictive maintenance, process optimization, and safety assurance.
