Hongqi Diaphragm Pressure Gauge Measures Micro Pressure

Hongqi Diaphragm Pressure Gauge Measures Micro Pressure

Basic Info.

1. Core Measurement Functions
Measurement Object: Micro-positive pressure, micro-negative pressure (vacuum), and micro-differential pressure
Measurement range: -80Pa to 60kPa (from tens of pascals to tens of thousands of pascals, significantly lower than ordinary pressure gauges)
Medium: primarily gases (air, gas, flue gas, etc.); requirements include no corrosion, no explosion hazard, no crystallization, and no freezing
II. Primary Functions and Applications
Safety Monitoring and Protection
Boiler / Industrial Furnace: Monitor furnace negative pressure, air duct pressure, and gas pressure to prevent backfire, explosion, or excessive negative pressure from damaging equipment.
Combustion System: Regulates the air-fuel ratio to ensure safe and efficient combustion.
Negative pressure equipment: Prevents vacuum overloading.
Process control
HVAC (Heating, Ventilation, and Air Conditioning): Measure duct static pressure and filter differential pressure to ensure ventilation and purification efficiency.
Food / Pharmaceuticals: Air pressure control for fermentation tanks and drying equipment.
Pneumatic system: pressure monitoring of the low-pressure air source and valve positioner.
Environment and Laboratory
Cleanroom, laboratory: Maintain positive pressure to prevent external contamination.
Meteorology and Environmental Protection: Micro-pressure measurement of atmospheric pressure and flue gas emissions.
medical equipment
Respirators and anesthesia machines: Precisely monitor airway pressure to ensure patient safety.
3. Core Features (Why Choose It)
Ultra-high sensitivity: capable of detecting extremely minute pressure changes (unmeasurable by ordinary pressure gauges).
High precision and minimal error: suitable for precise low-pressure measurements.
Compact Structure: Small size, lightweight, earthquake-resistant, and easy to install.
Weak overload resistance: Limited to micro-pressure scenarios, susceptible to damage under excessive pressure.
