Grounded
type
|
|
1. This type can withstand 350 MPa or more．
2. It is not suitable for location with electromagnetic
induction on radio frequency interference．

Ungrounded
type
|
|
1. This type has a slower response than the
grounded type but is more commonly used since
it is not restricted by the object to be measured．
2. The element is covered with an insulator thereby
ensuring a long life span．

Exposed
type
|
|
1. Since the element is exposed response time is
very fast.
2. This type is suitable for temperature measurement
of gases such as automotive exhaust.
3. This type is mechanically weaker than the others.
