Operating instructions
3.4 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.
4 General Description
The two-colour pyrometer 7MC3052-... detects temperatures and monitors
temperature ranges without contact.
The sensor detects the infrared energy radiated by a hot object and converts this
to an electric switch 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 7MC3052-... ratio pyrometer is designed for use in harsh industrial environ-
ments and offers a high level of functionality. The instruments are splash-proof
according to IP65 (DIN 40050). The pyrometer has an analog output and a switch
contact that can be used depending on the configuration as opener or closer.
Some types of the 7MC3052-...pyrometers are equipped with a LED spot light. The
LED spotlight shows the real size of the target spot.
