Temperature sensor / temperature switch with ATEX approval

UniEx.T temperature sensor/temperature switch with ATEX approvalTemperature switches and temperature sensors with ATEX approval are suitable for use in explosive media and environments 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.
For PT100/PT1000 temperature sensors, platinum measuring resistors according to DIN EN 60751, Class B are used.
These can be implemented in 2-, 3- or 4-wire technology.

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

UniEx.T temperature measuring devices are built according to customer specifications and can thus be individually configured and used for a wide variety of applications.

  • 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
  • High durability
  • The temperature sensor/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 temperature sensor/switch must be electrically connected to the equipotential bonding system of the plant.
