G

Grounded

1. Grounded thermocouple can withstand 350 Mpa or more.

2. Grounded thermocouple is not suitable fortemperature measurementlocation with electromagnetic induction on radio frequency interference.

Φ0.5~8.0

Φ3.0~8.0

Φ5.0~8.0

U

Ungrounded

1. Ungrounded thermocouple type has a slower response than the Grounded thermocouple but is more commonly used since ungrounded temperature probe isseparated with the medium.

2. Ungrounded thermocouple temperature element is covered with an insulatorthereby ensuring a long life span.

Φ0.25~8.0

Φ3.0~8.0

Φ5.0~8.0

U

Ungrounded Separate

1. Ungrounded separate thermocouple is often used with thermocouple with 2 functions, such as indication and control purpose.

2. Ungrounded separate thermocouple has same features as ungrounded typethermocouple.

E

Exposed

1. The element is exposed and the response time is fast.

2. Exposed thermocouple is suitable forgastemperature measurement.

3. This type is mechanically weaker than others.
