Industrial explosion-proof touch mouse with intrinsic safety design suitable for chemical oil and gas hazardous areas

Description :

  Explosion proof touch mouse is an input device designed specifically for hazardous environments such as petroleum, chemical, pharmaceutical, etc. that contain flammable and explosive gases or dust. It limits electrical sparks and thermal energy through special circuit design and shell packaging, ensuring safe use in hazardous areas such as Zone 1/Zone 2 or Div 1/Div 2, and solving the safety hazard of ordinary mice easily producing sparks and causing accidents under harsh working conditions. It is the core component of building an intrinsic safety industrial control system.

  The explosion-proof touch mouse usually adopts a high-strength aluminum alloy or stainless steel shell, and the surface is treated with anti-static spraying, with a protection level of IP65 or above, which can effectively prevent dust intrusion and water splashing. The internal circuit adopts intrinsic safety design, and the working voltage and current are strictly controlled within the safety threshold, in compliance with national standards such as GB 3836.1 and GB 3836.4. Some models support a wide temperature range and can adapt to environmental temperatures ranging from -20 ℃ to+60 ℃, ensuring stable operation under extreme weather conditions.

  When selecting, it is necessary to clarify the hazardous area level (such as gas group IIA/IIB/IIC) and temperature group (T1-T6) on site, to ensure that the equipment certification level covers the actual working conditions. Compared with ordinary industrial mice, explosion-proof touch mice focus more on sealing and impact resistance, but do not have waterproof diving function and are not suitable for underwater operations. If the site is in a highly corrosive environment, it is recommended to choose the stainless steel 316L material version and confirm whether the connecting cables have the corresponding chemical corrosion resistance to avoid electrochemical corrosion at the interface.

  During installation, ensure good grounding to avoid static electricity accumulation. The connecting wire should be connected to the intrinsic safety circuit through a safety barrier, and it is strictly prohibited to mix with non intrinsic safety equipment. In daily maintenance, regularly clean the surface oil and dust, check whether the shell has cracks or deformations, and whether the sealing ring has aged or failed. If a button malfunction or cursor drift is found, the connection circuit and power supply voltage stability should be checked first. Do not open the casing for maintenance while it is live. Professional personnel should perform maintenance or replacement in a safe area to maintain its explosion-proof performance.
