5.3 Cable Selection
5.3.1 Input signal Cable Selection
A dedicated cable is used for connection between the temperature sensor
and the temperature transmitter.
When a thermocouple is used as the temperature sensor, a compensation
wire which is appropriate for the type of thermocouple must be used (refer
to compensating cables for IEC584 thermocouples). When a resistance
temperature sensor (RTD) is used as the temperature sensor, 2-core/3-
core/4-core cable must be used (refer to resistance thermometer sensor
IEC751).
5.3.2 Output Signal Cable Selection
• Use cables of 0.13 to 2.08 mm
2
/ AWG26 to 14.
• For wiring in areas susceptible to electrical noise, use shielded wires.
• For wiring in high or low temperature areas, use wires or cables suitable
for such temperatures.
• For use in an atmosphere where harmful gases or liquids, oil, or solvents
are present, use wires or cables made of materials resistant to those
substances.
