Mini-Float Switch with ATEX approval for the process industry and industrial applications

UniEx.M mini float switch with ATEX approvalMini float switches with ATEX approval are suitable for use in explosive media and environments according to Directive 2014/34/EU. Mini float switches are passive devices and 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. UniEx.M mini 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.M now without obligation or arrange a consultation appointment!

Mini float switch in combination with temperature switch/sensor
Optionally, we equip the UniEx.M series devices with temperature switches/sensors. Both temperature switches, which open or close at a desired temperature, and temperature sensors, such as PT100/PT1000, can be combined with the mini-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 -20°C to 105°C in medium, -20°C to 70°C above mounting
  • High reliability and long life span
  • The mini 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 mini float switch must be electrically connected to the equipotential bonding system of the plan
