Heating can be electric,e.g. with heated elements, or by means of hot water or steam pipes made of copper or heatingjackets.• Risk of electronics overheating! Make sure that the maximum permissible ambient temperaturefor the transmitter is not exceeded. Consequently, make sure that the adapter between sensor andtransmitter and the connection housing of the remote version always remain free of insulatingmaterial. Note that a certain orientation might be required, depending on the fluid temperatureä 16. For fluid temperature of 150°C (302°F) or above the usage of the remote version withseparate connection housing is recommended.• With a fluid temperature between 200 °C to 350 °C (392 to 662 °F) the remote version of thehigh-temperature version is preferable.• When using electrical heat tracing whose heat is regulated using phase control or by pulse packs,it cannot be ruled out that the measured values are influenced by magnetic fields which mayoccur, (i.e. at values greater than those permitted by the EC standard (Sinus 30 A/m)). In suchcases, the sensor must be magnetically shielded.The secondary containment can be shielded with tin plates or electric sheets without privilegeddirection (e.g. V330-35A) with the following properties:– Relative magnetic permeability r 300– Plate thickness d 0.35 mm (0.014")• Information on permissible temperature ranges ä 134• Promass X: Especially under critical climatic conditions it has to be ensured that the temperaturedifference between environment and measured medium does not exceed 100 K. Suitablemeasures, such as heating or thermal insulation, are to be taken.Special heating jackets which can be ordered as accessories from are available forthe sensors.Page 20 • MN0M030Issue/Rev. 0.2 (12/12)
