S6025 Fluid Level Switch

ExS6011-T Dual Temperature Switch

This temperature switch is specifically designed for damper control in explosive atmospheres where flammable gases, vapors, or combustible dusts may be present, particularly in industries such as oil and petrochemicals. It is intended for use in conjunction with explosion-proof damper actuators.

The product holds domestic explosion-proof certification (China), as well as international ATEX and IECEx approvals.

72℃ Temperature Switch
Comprises two independent temperature switches: ambient temperature switch (TS1) and duct/ventilation opening internal temperature switch (TS2).

  • TS1 trips (opens) when the ambient temperature exceeds 72℃;
  • TS2 trips (opens) when the duct internal temperature exceeds 72℃.

150℃ Temperature Switch
Comprises two independent temperature switches: ambient temperature switch (TS1) and duct/ventilation opening internal temperature switch (TS2).

  • TS1 trips (opens) when the ambient temperature exceeds 150℃;
  • TS2 trips (opens) when the duct internal temperature exceeds 150℃.

Compliant with the following standards:

  • IEC 60079-0:2017 / EN 60079-0:2018 – Explosive atmospheres – Part 0: Equipment – General requirements
