Armoured thermocouple form or characteristic

Form	Configuration	Characteristic
Stick out Type		Reaction quickly, suitable for measuring temperature of the engine exhaust, mechanism intensity is lower。
Bottom tangency Type		Reaction quickly, press-resistant can reach3.4*10MPa; be unfit for the occasion have electromagnetism interferential
Isolation		Reaction slower than both of preceding， use life is long； stick up to electromagnetism and intervene； for no especial request quick-respond occasion introduce this form excessive usually.
separate isolation		Prevent signal jam of two tubes, its function as Isolation type
