Abstract

The invention discloses a pin-type piezomagnetic sensor and a control system comprising the same. The pin-type piezomagnetic sensor comprises a sensor body, wherein the sensor body mainly comprises a piezomagnetic element, the piezomagnetic element comprises a central bearing cylinder, a support, a cross excitation magnetic core and a winding thereof, an induction magnetic core and a winding thereof, and an intermediate magnetic circuit; the cross-shaped excitation magnetic core is fixed at the central position of the central bearing cylinder; an X-direction excitation winding NX and a Y-direction excitation winding NY are arranged on the cross-shaped excitation magnetic core; and the two ends of the central force bearing cylinder are each provided with a support, an induction magnetic core is installed on each support, and an induction winding is arranged on each induction magnetic core. Compared with a traditional piezomagnetic force sensor, the pin-type piezomagnetic sensor has the advantages that: the defect that the measuring range is large but the precision is not accurate can be overcome, and the high precision is guaranteed when the large measuring range is achieved; and the device capable of automatically adjusting the measuring range is arranged, the measuring range can be adjusted according to the requirement of the using environment, more measuring environments can be adapted, and energy consumption is lower.

Description

technical field [0001] The invention relates to a magnetostrictive sensor with improved sensitivity by improving the internal magnetic circuit structure and a control system including the sensor, belonging to the technical field of force measurement. Background technique [0002] Force is one of the important parameters commonly used in engineering applications. The measurement of force is extremely important in practical work. It is directly related to factors such as work safety and efficiency. It is often used in industry to produce certain physical effects under the action of force, such as The piezoelectric effect, the piezoelectric effect, etc., convert the force into an electrical signal proportional to the magnitude of the force to measure the force. [0003] The magnetostrictive sensor is made of magnetostrictive material as the piezomagnetic element, which is made by using the magnetostrictive effect. Its working principle is to convert the change of external force...
