Guideline 1 General 2 Principle of function of electric thermometers 1 General Electric thermometers transfer the physical temperature value into a temperature dependent signal. They are closed constructive components delivering output signals for further treatment. In most cases auxiliary energy sources are necessary dependent on the sensor type. The good transmission of those electrical signals over far distances offer a great advantage. The reception of the measured value and the reading place of the temperature can be far away from each other. The measuring signals can easily be integrated...

Guideline 3 Installation and first initiation of thermometers 3 Installation and first initiation of thermometers 3.1 Spacial arrangement of thermometers In general, electrical thermometers work independently of their position. The preferred mounting position is „vertically suspended” that means connection head on the top and protecting tube below. 3.2 Installation of thermometers Usual installation methods are: » screwed thread (cylindric and conical outer thread) » swivel nut with inner thread » adjustable flanges and counter flanges, only tight with small gas pressures » welded flanges » adjustable...

Guideline 4 Measuring cables 4 Measuring cables 4.1 General The cables have to be chosen that they are appropriate for the corresponding environment that means resistant against thermal, mechanical and chemical influences. All cable connections have to be well done. Measuring cables shall be laid separately and > 0.5 m away from supply cables and cross the latter rectangular. All measuring circuits shall be operated ungrounded; if necessary a one point grounding is recommended. In order to avoid electrostatic or magnetic interference the cables shall be screened respectively have twisted cores....

Guideline 5 Maintenance 5 Maintenance 5.1 Returning inspections Thermometers and their measuring circuits shall be controlled regularly (1 to 12 months) with regard to: » mechanical, thermal, chemical damage of the protecting tubes » corrosion and bad contacts at cable connections » tightness of connection heads » function of the measuring circuits (drifts, insulation resistance) 5.2 Control of measuring circuits Loosen cable connections in connection head and check instruments with regard to the operating temperature for » thermocouples with mV signal » for resistance thermometers with test...
