UHZ-62EX/CN explosion-proof stainless steel magnetic flip plate level meter

Explosion-proof 316 stainless steel magnetic flap level meter: the preferred liquid level measurement in flammable and explosive environments

What is the explosion-proof 316 stainless steel magnetic flap level gauge?

The explosion-proof 316 stainless steel magnetic flap level meter is a liquid level measuring instrument specially designed for flammable and explosive environments such as petroleum, chemical, pharmaceutical, and natural gas. It uses a 316L stainless steel main body, offering excellent corrosion resistance. The remote transmission transmitter section features either explosion-proof (Exd) or intrinsically safe (Exia) explosion-proof design to ensure safe operation in hazardous environments containing combustible gases, vapor, or dust.

This product can achieve on-site intuitive liquid level display via red-and-white flipping columns (no power supply required, intrinsically safe), and can also output 4-20mA signals or RS485 communication to the control room via explosion-proof remote transmission transmitters, enabling remote monitoring and alarm interlock.

Explosion-proof rating explanation

T6 grade: The maximum surface temperature of the equipment is ≤85°C, suitable for most flammable gas environments.

Core advantages

• Complete explosion-proof certifications: Exd IICT6 / Exia IICT6 / Exe IICT6, meeting the requirements of different hazardous areas

• 316L stainless steel material: Corrosion resistance superior to 304, suitable for seawater, chloride ions, and acidic or alkaline media

• Intrinsic safety display: The on-site flipping column is a purely mechanical structure, requiring no power supply and eliminating any risk of electric sparks

• Dual liquid level monitoring: on-site display + explosion-proof remote transmission signal, enabling dual confirmation between on-site and central control rooms

• High temperature and high pressure resistance: operating temperature -40°C~350°C, pressure ≤ 6.4MPa (customizable higher)

• Multiple sealing protections: The junction box and main conduit connections all use explosion-proof sealing structures

• Optional accessories are complete: explosion-proof alarm switch, explosion-proof liquid level transmitter, explosion-proof junction box

Technical specifications

Explosion-proof vs. standard model comparison

Typical application scenarios

• Petrochemicals: Liquid level measurement for refinery storage tanks, reactors, and towers

• Pharmaceutical industry: solvent storage tanks, alcohol tanks, extraction towers (containing flammable solvents)

• Natural Gas/Liquefied Gas: LNG/LPG storage tanks, gas-liquid separators

• Paint and coatings: solvent-based paint storage tanks, thinner tanks

• Coal Chemicals: Methanol, ethanol, benzene storage tanks

• Gas stations: Underground oil storage tank level monitoring

• Fine chemicals: flammable and explosive intermediate storage tanks

Key points for model selection

Provide the following parameters to the manufacturer to obtain an accurate selection plan:

1. Measurement range: Center distance between upper and lower flanges (mm)

2. Name and nature of the medium: whether it is corrosive, whether it is flammable or explosive

3. Operating temperature and pressure: maximum/minimum temperature and pressure

4. Explosion-proof zone level: Zone 0/1/2? Gas Groups (IIA/IIB/IIC)?

5. Remote transmission required: 4-20mA / RS485 / alarm switch

6. Remote Transmission Signal Type: Two-wire or Four-Wire?

7. Electrical interface specifications: M20× 1.5 / G1/2 / 1/2 NPT

8. Connection flange specifications:D N20/DN25? Standards (China/US/Japan)?

9. Whether insulation/heat tracing is needed: anti-freezing or anti-freezing requirements

Explosion-proof installation precautions

1. Cable entry: must use explosion-proof sealing joints (cable sealing rings intact, cable outer diameter matched)

2. Junction box sealing: After wiring is completed, tighten the box cover bolts evenly to ensure the explosion-proof surface fits tightly

3. Grounding requirements: The explosion-proof enclosure must be reliably grounded to prevent static electricity accumulation

4. Strictly prohibit opening the lid while energized: Explosion-proof junction boxes must not be opened while powered on

5. Cable selection: Use armored cables or use explosion-proof flexible conduits for protection

6. Installation location: Avoid high-temperature heat sources and strong vibration sources

7. Regular inspection: Check for rust on the explosion-proof surfaces and aging of the sealing rings

Common faults and troubleshooting

Explosion-proof maintenance reminder: Any maintenance operation involving explosion-proof junction boxes must be performed after the power is cut off and operated by personnel with explosion-proof qualifications.
