TCA Hazardous Area Sensors IECEx Certification

Temperature Controls Pty Ltd are able to offer temperature assemblies suitable for use in the above environments. The use of any electrical apparatus in these areas is strictly controlled by using the above protection techniques.

Temperature Controls Pty Ltd have obtained IECEx approval for thermocouple and RTD Assemblies, suitable for use in flameproof , combustible dusts ( Area 21 & 22 ) and increased safety classified installations.

The certification covers the terminal head and temperature element providing IECEx approval for the complete assembly.

Terminal heads or temperature elements (Thermocouples / RTD sensors) may be supplied as components to suit your application.

Do you know ?

Ex d Flameproof Protection (Use in zones 1 & 2)

All electrical connections and equipment are enclosed in a housing strong enough to contain any explosion or fire that may take place inside the housing.

Ex tD Combustible Dust Protection (Use in zones 21 & 22)

All electrical connections and equipment are enclosed in a housing limiting the maximum surface temperature of the enclosure and restricting the ingress of dust by using dust tight or dust protected enclosures.

Ex e Increased Safety (Use in zone 2)

All electrical connections and equipment incorporate special measures to reduce the probability of excessive temperatures and the occurrence of arcs and sparks in normal service.

Ex ia Intrinsically Safety (Use in zones 0, 1 & 2)

The electrical energy available in circuits and equipment, is limited to a level too low to ignite the most easily ignitable mixtures in a hazardous area. Intrinsically safe barriers, Zener or Transformer Isolated, are installed in the circuit to limit current and voltage in the hazardous area to prevent sparking under fault conditions.
