Pressure transmitter mainly has capacitance pressure transmitter and diffused silicon pressure transmitter, ceramic pressure transmitter, answers Variant pressure transmitter etc..Pressure transmitter is divided into general pressure transmitter (0.001MPa~35MPa) according to pressure measurement scope With differential pressure transmitter (0~1.5kPa), three kinds of negative pressure transmitter.
The Main Function of pressure transmitter passes to electronic equipment pressure signal, and then in its principle of Computer display pressure Generally:By the mechanical signal of this for hydraulic pressure pressure be transformed into the such electronic signal pressure of electric current (4~20mA) and voltage or Size of current is linear, usually proportional relation.
Pressure transmitter is by measuring diaphragm, measured medium to be delivered on semiconductor silicon diaphragm, then passes through scale On Wheatstone bridge measure, when ambient pressure changes, Wheatstone bridge can accordingly change, thus Measure pressure.
Present pressure transmitter in use, needs to ensure the pressure stability in whole measurement process, slow becomes Change, and interiors of products can not block.Such product is limited by the impact of compression shock and low ambient temperature it is impossible in water conservancy, water The fields such as electricity play one's part to the full.
In use, when equipment starts, manifold pressure can reach positive normal pressure in moment to existing pressure transmitter The several times of power, the directly infringement to damaging property of product.Meanwhile, the liquid in the case that ambient temperature is too low, in pipeline Due to volumetric expansion after body icing, can cause local excessive pressure in interiors of products, equally product can be caused irreversible Damage.
Utility model content
