Description
Technical field
Pressure transmitter research field is the utility model is related to, in particular it relates to a kind of pressure that can avoid precipitating accumulated slag
Power transmitter device.
Background technology
Pressure transmitter is a kind of to convert pressure into pneumatic signal or electromotive signal is controlled equipment with teletransmission.
The physical pressure parameters such as gas that load cell is experienced, liquid can be transformed into the electric signal of standard by it
(such as 4~20mADC), measured with supplying the secondary meters such as indicator alarm, recorder, adjuster, indicate and process adjust
Section.
Pressure transmitter is a kind of sensor the most commonly used 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,
