The invention discloses a differential pressure sensor assembly and a differential pressure controller having the same. The differential pressure sensor assembly includes a sensor shell, a high-pressure sensor and a low-pressure sensor. One end of the high-pressure sensor and one end of the low-pressure sensor are arranged in the sensor shell. The other end of the high-pressure sensor and the other end of the low-pressure sensor are arranged outside the sensor shell. The upper ends of the high-pressure sensor and the low-pressure sensor are provided with pressure deformation devices. The differential pressure sensor assembly also includes a differential pressure transmission lever. The differential pressure transmission lever is horizontal arranged. One end of the differential pressure transmission lever is arranged on the upper end of the pressure deformation device in the high-pressure sensor, the other end is arranged on the upper end of the pressure deformation device in the low-pressure sensor, and the middle part is pivoted to the sensor shell. The differential pressure sensor assembly also includes an ejection rod. The ejection rod is arranged on one side of the sensor shellclose to the high-pressure sensor. Moreover, one end of the ejection rod is connected to one end of the differential pressure transmission lever at the high-pressure sensor. The differential pressuresensor assembly of the invention and the differential pressure controller having the same have the advantages of simple structure, good working stability, good repeatability and wide application prospect.
Description
technical field [0001] The invention relates to the technical field of differential pressure controllers, in particular to a differential pressure sensor assembly and a differential pressure controller having the same. Background technique [0002] A differential pressure sensor is a sensor used to measure the difference between two pressures, usually used to measure the pressure difference between the front and back ends of a device or component. Differential pressure sensors are the core components of differential pressure measurement and control instruments, and there are many varieties. Widely used in textile workshops, boiler air supply, underground ventilation and other fields of electricity, coal, spinning cotton boxes, dust removal equipment, industrial pressure process control, etc. [0003] Differential pressure controller refers to a series of automatic control elements that cause physical deformation inside the controller according to the difference between the ...
