Stainless Steel Pressure Type Thermometer Anti Corrosion For HVAC Services

The all-stainless steel pressure type thermometer is an anti-corrosion upgraded version of the ordinary pressure type thermometer. All metal parts that come into contact with the measured environment or are exposed are made of stainless steel.

• All-stainless steel construction: The bulb, capillary tube, and case are all made of stainless steel, offering strong corrosion resistance and suitability for neutral corrosive liquid and gas media.
• Shock-resistant design: Some models are filled with silicone oil inside, enabling them to withstand vibration environments and ensuring stable pointer indication.
• Intuitive reading: The on-site dial directly indicates temperature without the need for external power supply, ensuring intrinsic safety.
• Remote transmission function: It can output 4-20mA, 0-10mA or contact signals, facilitating remote monitoring and automatic control.
• Diverse structures: Available in axial, radial, and universal types, among others, to meet various on-site requirements.

• Measurement Range: Gas medium -50℃ to 550℃, liquid medium -20℃ to 350℃, steam medium 0℃ to 250℃. All stainless steel structure enhances high-temperature stability.
• Accuracy Class: Industrial grade 1.5 (commonly used), precision grade 1.0, repeatability better than ±0.3%.
• Corrosion Resistance and Pressure Resistance: 304 stainless steel resists fresh water and light oil stains; 316L resists acids, alkalis, salt spray, and oil gas; Hastelloy resists strong corrosion (such as hydrogen sulfide, dilute nitric acid); conventional pressure resistance ≤2.5MPa, thick-walled type can reach 4.0MPa.
• Response Time: τ0.9 ≤ 30s (close range) to 100s (50m armored capillary), liquid medium type responds faster than gas type.
• Environmental Adaptability: Operating environment temperature -20℃ to 70℃, relative humidity ≤95%, salt spray resistance ≥96 hours (conforms to GB/T 10125), vibration resistance ≤3g.

All-stainless steel pressure-type thermometers are specifically designed for applications where there are requirements for corrosion resistance or hygiene.

• Food and beverage industry: Beer fermentation tanks, milk pasteurization lines, juice storage tanks, food processing equipment.
• Pharmaceutical and biotechnology: Reactors, mixing tanks, purified water systems, clean pipelines.
• Chemical industry: Measurement of slightly corrosive chemical raw materials, solvents, process water, etc.
• Marine and offshore engineering: Monitoring the temperature of seawater, fuel oil, and lubricating oil in engine rooms, capable of resisting marine salt fog corrosion.
• Water treatment industry: Temperature monitoring in wastewater treatment and seawater desalination facilities.
• Outdoor or high-humidity environments: Monitoring equipment exposed to wind and rain for long periods.

All-stainless steel pressure-type thermometers are the "fortress" of mechanical temperature measurement in harsh environments. Through an all-stainless steel structure, they perfectly combine the inherent advantages of pressure-type thermometers, such as robustness, explosion-proof, vibration resistance, and no power supply requirement, with excellent corrosion resistance and hygiene. In industries such as food, pharmaceuticals, chemicals, and shipping, which have strict requirements for corrosion and hygiene, they offer a reliable, safe, and maintenance-free temperature measurement solution, serving as a model that bridges traditional mechanical reliability with modern industrial hygiene standards.
