1, the basic structure form

HOSSN thermal elements are basic structure forms: diaphragm, rubber hose, plunger.

2, work principle,

Sealed in a casing thermal expansion of the material, after exposure to the set temperature sensing, expansion, under the influence of inflation pressure, with components in rubber seal putter move to drive components. Heat energy into mechanical energy, and the element push rod to produce an upward displacement, element putting upward displacement is used to realize various functions of automatic control. Element is returned after the set temperature drop of push rod by weight load.

3, Hao sen bulb features:

(1) the size is small, occupy the space is little, and the element size, structure is designed according to the need to the workplace.

(2) adjust temperature accurate and reliable.

(3) no vibration, stable working process.

(4) components do not need special maintenance, maintenance.

(5) the long service life.

4, the main technical performance parameters:

(1) the push rod height: thermal element assembly size height shall be determined in accordance with the drawings and technical documents.

(2) the push rod displacement: associated with the temperature range of components, range from 1.5 ㎜ ~ 20 ㎜ effectively.

(3) temperature range: HOSSN thermal element can control range from 0 ℃ ~ 130 ℃.

(4) hysteresis: rising curve and the trip itinerary decline curve, there is gap between delay element temperature and element action when parts of the friction between the parts is the cause of hysteresis, hysteresis in 1 ~ 2 ℃ in general.

(5) the negative gravity: according to different components overall dimensions, the thermal element to bear weight load.
