Hongqi Full Stainless Steel Shock-Proof Capsule Pressure Gauge

Hongqi full Stainless Steel Shock-Proof  capsule  pressure gauge

This gauge adopt capsule as the sensitivity part, can measure the micro-pressure or negative pressure of the gases which have no corrosion function to the copper alloys and have no explosion.And it is widely used in boiler ventilation, gas tube and fuel setting and so on.

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.
