Explosion-proof

Explosion-proof thermocouples

Flameproof thermocouples to CNS 3376 (IEC 60079) and CNS 15591 (IEC 61241), and Ex heads with a digital indicator. Explosion-proof RTDs are under Resistance temperature detectors (RTD).

Flameproof thermocouples & RTDs

Hazardous areas are places where a loss of temperature control or a leak can form an explosive mixture. Thermoway's explosion-proof sensors are designed and type-approved to CNS 3376 (IEC 60079) and CNS 15591 (IEC 61241).

  • For gas and dust zones such as Zone 1 / Zone 21
  • Flameproof (d) and dust-protected (tD) construction
  • Optional built-in transmitter or indicator
