Float switch with ATEX approval

UniEx.SS_Float switch with ATEX appovalFloat switches with ATEX approval are suitable for the use in explosive media and atmospheres according to Directive 2014/34/EU.
Float switches are passive devices. They do not require a power supply. All standard ATEX devices are offered for a temperature range of -20°C to +105°C in the medium, or -20°C to 70°C above process connection. Our high temperature devices are suitable for an operating temperature of -40°C to +180°C. UniEx.SS float switches are manufactured according to customer requirements and can therefore be individually configured and used for a wide range of applications.

Simply configure and request UniEx.SS now without obligation or arrange a consultation appointment!

Float switch in combination with temperature switch/sensor
Optionally, the UniEx.SS series devices can be equipped with temperature switches or sensors. Both temperature switches, which open or close at a desired temperature, and temperature sensors, such as PT100/PT1000, can be combined with the float switch.

  • Level measurement in many liquid media, e. g. water, oil, fuel
  • Large field of application due to the proven functional principle:
    Monitoring of processes, predetermined levels as well as pumps and level controls
  • Chemical industry, petrochemical industry, mechanical engineering, shipbuilding industry, offshore facilities, energy plants and others
  • areas of application are, for example, barrier pressure vessels, agitators or printing machines
  • Temperature range from -40°C-180°C
  • High reliability an long life span
  • The float switch may only be operated with certified intrinsically safe circuits with the permissible maximum values.
  • The device must be included in the periodic pressure/safety test of the container
  • The float switch must be electrically connected to the equipotential bonding system of the plant.
