Description
Technical field
The invention belongs to sensor technical field, more particularly to a kind of pressure inverting suitable for microwave hydrothermal reactor
Device.
Background technology
Pressure transmitter be it is a kind of convert pressure into pneumatic signal or electromotive signal is controlled equipment with teletransmission, it
The physical pressure parameters such as gas that load cell is experienced, liquid 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 is industrial practice
In a kind of the most commonly used sensor, it is widely used in various industrial automatic control environment, is related to water conservancy and hydropower, railway traffic, intelligence
It can build, produce numerous industries such as automatic control, Aero-Space, military project, petrochemical industry, oil well, electric power, ship, lathe, pipeline.
Microwave heating is totally different from traditional heating mode, and microwave quickly penetrating material and couples with polar molecule repeatedly,
Microwave energy is converted into material interior energy, realizes overall, uniformly heating, significantly shortens the heat time, reduce the heat of heating process
Loss, significantly energy-conservation.Microwave attenuation materials method is to combine the advantage of microwave and hydro-thermal method, fast with reaction speed, product particle size
Controllable and purity is high, better crystallinity degree, reunites the features such as few；With pressure transmitter detection reaction pressure in microwave hydrothermal reactor
Power, there is the process of easily studied reaction；But in microwave hydrothermal reactor, under microwave and hot conditions, traditional barrier film
It is vulnerable to adverse effect, so as to influence the precision of pressure transmitter.
The content of the invention
