Analogue level measurement reed chain with ATEX approval

UniEx.ANM_analogue level measurement with ATEX approvalThe UniEx.ANM series level measuring devices with ATEX approval are suitable for use in explosive media and environments according to Directive 2014/34/EU. The level meters 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.ANM level measuring devices are manufactured according to customer requirements and can therefore be individually configured and used for a wide range of applications.
