Answer Posted / guest
A therocouple is composed of two unlike metals connected
together. The unlike metals produce a milivolt output
signal, which varies in relation to temperature difference
detected at the junction (heat applied at the junction
increases milivolt output). The therocouple is connected to
a converter (transducer) which takes the milivolt input
signal to a milliamp output signal (usually 4 to 20
milliamps) to a temperature control device.
The standard 100 ohm RTD elements used in probe type
assemblies are made of pure platinum wire wound about a
ceramic or glass core and hermetically sealed within a
ceramic or glass capsule. The sensor varies resistance in
relation to temperature change.
Both devices serve the same purpose of detecting
temperature, the RTD varies resistance, the therocouple
produces voltage.
