Operators (Ex 'de') Pilot Light

The WH - WP operators and WA instruments are normally used in the chemical and petrochemical plants, off-shore platforms, refineries and any other industry where hazardous atmospheres (gas and combustible dust) are potentially present.

The WH - WP - WA range has been designed to meet the main requirements of power distribution, monitoring and signaling, and other electrical functions inside the hazardous area of the plant.

Customers can still purchase even if there is no stocks available

Unit Of Measurement (UOM):

The material used to manufacture the UH-UP operators and WA instruments have been studied to grant the maximum protection against the highly corrosive agents present in these industries:

  • the external components (handle, push-button, diffuser, ect.) are made of high-quality antistatic and UV-protected polymers and provided with EPDM sealing to mantain the IP66 level of protection of whole control station;
  • the internal Ex d components are made of high quality thermoplastic and are available for standard installation on cover or, as option, on a dedicated mounting rail;
  • the LED units for pilot light and luminaire push button are available with two range of voltage as indicated in the ordering table;
  • the high brightness and the electrical life of LED units are granted for a minimum of 100,000 hours;
  • the diffuser of pilot lights and luminaire push button units have a special design to grant a high visibility degree in any situation
