2.4 Electromagnetic Compatibility
The devices comply with the essential safety requirements of the Electromagnetic
Compatibility Directive 2014/30/EU (EMC Act)�
When connecting a power supply unit, make sure that is also conforms to these
standards� Radio interference may arise if the pyrometer is interconnected with
such peripheral devices which have not been properly interference-suppressed�
This may necessitate additional interference suppression measures�
3 General Description
The pyrometer optically detects temperatures and monitors temperature ranges�
The sensor detects the infrared radiation emitted by objects and converts it into an
electrical switching signal, an analogue signal and a digital signal�
The advantage of this technique is that there is no mechanical contact between
the sensor and the hot object�
The instrument is suitable for the following applications:
• Measurements at moving or hard-to-reach objects
• Measurements at surface-treated or voltage-carrying objects
• Measurements at sticky materials such as dough or aggressive chemicals
• Applications requiring fast response times�
The rugged stainless steel housing enables the instrument to be used in harsh
industrial environments� The instruments are splash-proof according to IP65 (DIN
40050)� The pyrometer has an analog output, an IO-Link switching output and
a switch contact that can be used depending on the configuration as opener or
closer�
