Applications of Intrinsically Safe Temperature & Humidity Transmitter LFH71

Intrinsically safe explosion-proof temperature and humidity transmitters are mainly used in hazardous environments with explosive gases, dust or steam to ensure that the equipment will not cause explosions in normal or faulty conditions. The following are typical application scenarios and industries:

1. Oil and gas industry

- Scenarios:

- Oil and gas drilling platforms (easily leaking explosive gases such as methane and hydrogen sulfide).

- Storage tank areas and pipeline transportation systems in refineries and chemical plants.

- LNG (liquefied natural gas) processing and storage facilities.

- Function: Monitor ambient temperature and humidity to prevent equipment corrosion or abnormal gas concentration.

---

2. Chemical and pharmaceutical industries

- Scenarios:

- Reactors, solvent storage rooms (flammable and explosive chemicals such as ethanol and acetone).

- Dust environments (such as powder medicine production workshops).

- Function: Control production environment parameters to avoid explosions caused by static electricity or high temperature.

---

3. Coal Mines and Underground Operations

- Scenarios:

- Coal mines (methane and coal dust explosion risks).

- Tunnel construction (gas accumulation areas).

- Function: Real-time monitoring of the temperature and humidity of the ventilation system to ensure operational safety.

---

4. Grain and Storage Industry

- Scenarios:

- Granaries, flour mills (dust explosion hazards).

- Ethanol warehouses or alcohol production workshops.

- Function: Prevent dust accumulation or excessive humidity from causing spontaneous combustion.

---

5. Aerospace and Military Industry

- Scenarios:

- Fuel filling areas (aviation kerosene vapor).

- Ammunition storage warehouses.

- Function: Ensure safety monitoring in extreme environments.

---

6. Other Hazardous Environments

- Scenarios:

- Sewage treatment plants (flammable biogas).

- Printing workshops (volatile ink vapor).

- Battery production (volatile gases from lithium battery electrolytes).

Why is intrinsic safety explosion-proof necessary?

- Safety standards: Comply with international explosion-proof certifications such as ATEX, IECEx, and UL.

- Technical features:

- Limit circuit energy to ensure that sparks or high temperatures are not sufficient to ignite explosives.

- Usually used in conjunction with isolation barriers (safety barriers) to further reduce risks.

This type of sensor is a key device for safety monitoring in high-risk areas and must be installed and maintained in strict accordance with specifications.
