only remove the measuring insert in a de-energised state!
Reduced response times with special KROHNE design KROHNE can offer a special design with a bottom sleeve between the thermowell and measuring insert See Fig. 2.
For thermowell with diameter Ø 6 mm, the measuring insert TR100 is Ø 3 mm.
The air gap between the thermowell and the measuring insert is normally 0,1-1 mm.
Pt100 measuring inserts A measuring insert with a Pt RTD is connected according to DIN EN 60751 in three different wiring variants from left to right:
When replacing both a separately certified intrinsically safe temperature transmitter and a separately certified intrinsically safe measuring insert with an identical device from the manufacturer, always refer to the Ex documentation for the devices.
Always include the thermometer and its measuring insert as per EN 60079-14 in the equipotential bonding of the installation site when installed correctly, the fixing screws guarantee this.
a connection head and an exchangeable measuring insert.
Ensure that the measuring insert is not heated by the effects of additional heat radiation(sunshine,
ensure that all the cables leading to the measuring insert are de-energised themselves
Resistance thermometer The measuring insert with a resistance thermometer features a temperature-sensitive sensor made from a platinum RTD, whose value at 0 C/ +32 F is 100 Ω.
is located in the replaceable measuring insert.
Electrical connections 4.1 General notes Industrial thermometers are connected to an electricity supply by connecting the sensor circuit in the connection head to the interchangeable measuring insert.
The supply voltage of an industrial thermometer specifically refers to the supply voltage of the measuring insert for further information refer to Electrical data on page 20.
Improved vibration resistance thanks to fixed measuring insert If strong vibrations exist, the spring load is not strong enough to hold the measuring insert fixed and it will hit against the interior wall of the thermowell,
Mineral isolated measuring inserts with thermocouples or stable Pt100 measuring resistances.
KROHNE measuring inserts are designed to provide the best possible response time.
To avoid injury and material damage, only operate the measuring inserts under the following conditions.
Equipotential bonding Always include the measuring inserts in the equipotential bonding of the installation site when installed correctly, the fixing screws guarantee this.
The manufacturer offers measuring inserts with a terminal block, free connection wires
