Electrical connections 4.1 General notes The actual temperature sensor, either a Pt100 RTD or a thermocouple,is located in the replaceable measuring insert.
Slide the measuring insert completely into the thermowell until the washer disc on the measuring insert almost touches the floor of the connection head.
You can replace a separately certified intrinsically safe temperature transmitter or measuring insert with an identical device from the manufacturer.
If you are operating the measuring insert together with a transmitter, pay attention to the details of the power supply in the Ex documentation of the transmitter used.
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.
If you are operating the measuring insert together with a transmitter, pay attention to the details about the power supply in the Ex documentation of the transmitter used.
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.
