Specifications

Resistance-bulb Temperature Transducers
These temperature transducers measure temperature by the change in resistance value of
a resistance bulb and output DC current or DC voltage proportional to the temperature of
the part measured.
Applications
Transmission of temperature signals to temperature monitors or temperature control
equipment
Temperature measurement of things such as voltage transformer oil

Selection between insulated/non-insulated (between input and output)
Make a selection according to the temperature sensor configuration explained in the following table.
Both insulated and non-insulated units can be used.
However, if the temperature sensor is located close to a power supply line or control equipment, common mode noise due
to electromagnetic induction may occur. Use an insulated unit in this case.
Make sure to use insulated units to prevent circuit noise interference due to the common potential generated in
temperature sensors and the penetration of external noise.

Use these temperature transducers in combination with a 3-wire resistance bulb. If a 2-wire resistance bulb is used, error may occur due to the influence of
lead-wire resistance.
For 3-wire resistance bulbs, set the resistance values of the respective lead wires between the resistance bulb and the transducer to 10Ω or less. Additionally,
set the difference among the lead-wire resistance values to within the values in the table below.
The accuracy (grade) indicates the accuracy of the temperature transducer only and does not include the error of the resistance bulb. Additionally, the
customer is requested to provide the resistance bulb.
When resistance bulb input stops, burnout output is performed on the positive side.
The temperature error due to resistance differences in
the table on the left is approximately 0.5K.
