Technical field
The utility model is related to fields of measurement, and in particular to constant temperature dissepiment formula pressure transmitter.
Background technology
On pipeline used in pipeline medium conveying, it will usually need to use pressure transmitter to detect and convey Jie
The signal of the Parameters variations such as pressure, the flow of matter, realizes remote auto control.
Pressure transmitter is the most commonly used a kind of sensor in industrial practice, and it is widely used in various industrial automatic control rings
Border, be related to water conservancy and hydropower, railway traffic, intelligent building, production automatic control, Aero-Space, military project, petrochemical industry, oil well, electric power, ship,
Numerous industries such as lathe, pipeline.Pressure transmitter is the liquid level, density and pressure for measuring liquid, gas or steam, then
Pressure signal is transformed into 4~20mA DC signal outputs.
Current pressure transmitter does not consider the requirement of temperature generally, and operation temperature depends on the temperature of measurement medium.And peace
Complex process during dress.
Utility model content
Technical problem to be solved in the utility model is conveniently to install, the good constant temperature dissepiment formula pressure of stability
