Description
Technical field
The utility model relates to a kind of transmitter more particularly to a kind of novel pressure transmitters.
Background technique
Pressure transmitter is a kind of equipment for converting pressure into pneumatic signal or electromotive signal carries out control and teletransmission.It
The physical pressures parameters such as gas, liquid that load cell is experienced can be transformed into the electric signal of standard, referred to supply
Show that the secondary meters such as alarm, recorder, adjuster are measured, indicated and procedure regulation.Pressure transmitter have electrodynamic type and
Pneumatic type two major classes.Pressure signal is passed to electronic equipment by the main function of pressure transmitter, and then in Computer display pressure
Its principle is about：The mechanical signal of this pressure of hydraulic pressure is transformed into electric current.So transmitter output voltage or electric current with
Pressure increases and increases two kinds of the measured medium for thus obtaining the relational expression pressure transmitter of a pressure and voltage or electric current
Pressure is passed through high and low two pressure chamber, and low pressure chamber pressure uses atmospheric pressure or vacuum, acts on the two sides isolation diaphragm of sensing element
On, measuring diaphragm two sides are transmitted to by the filling liquid in spacer and element.Existing pressure transmitter detects pressure sensibility
Poor and non-refractory, heat-sinking capability are poor.
Utility model content
In view of the above problems, the object of the present invention is to provide a kind of measured pressure value stabilization, high temperature resistant and heat radiation energies
The preferable novel pressure transmitter of power.
