Description
Technical field
The utility model belongs to robotization flow measurement instrument transmitter, relates to the measurement of magnetic field displacement.
Background technology
Prior art has two kinds at present.First kind is to move through magnetic coupling by float to drive needle pivot, drives the condenser type angle transducer by needle pivot by linkage assembly again, reaches the purpose that magnetic displacement is measured.This kind technical costs height (angle transducer is import), mechanical hysteresis is big, and precision is low, and no field digital shows.Directly experience the displacement of float magnetic field by Magnetic Sensor for second kind, gather and handle by microprocessor, and show instantaneous and integrated flux.This technical disadvantages shows:
(1) owing to be subjected to the influence of measuring tube bore and chuck, make the distance of float magnet steel and Magnetic Sensor be restricted, Magnetic Sensor institute measuring magnetic field intensity a little less than, very easily be subjected to the influence of external magnetic field and ferromagnetic material.
(2) since the float magnet steel in detected fluid, ferromagnetic material is all influential to float magnet steel magnetic field in the temperature of fluid and the fluid, causes the float changes of magnetic field, causes measuring result error.
Summary of the invention
The purpose of this utility model is to solve the defective that above-mentioned prior art exists, and a kind of precision height, reliability height, magnetic coupling digital display metal pipe float flow meter indicator that antijamming capability is strong are provided.
The purpose of this utility model is achieved in that
A kind of magnetic coupling digital display metal pipe float flow meter indicator, it has housing, it is characterized in that: housing is made up of lid and box body, in the inner chamber of housing, needle pivot is arranged, on this needle pivot by pointer is housed behind the forward direction successively, counterweight, the sensing magnetic steel sleeve, axle sleeve, the servo-actuated magnet steel, dial plate is equipped with in back at pointer, liquid crystal board is equipped with in the back of dial plate, between described counterweight and the sensing magnetic steel sleeve wiring board is arranged, on the described wiring board Magnetic Sensor is housed, two sensing magnet steel that form an angle are arranged on the described sensing magnetic steel sleeve, and described liquid crystal board is affixed with support column and wiring board, described wiring board, dial plate is affixed with support column and lid respectively; Described axle sleeve is fixed in lid.
The utility model has following actively useful effect:
Magnetic coupling digital display metal pipe float flow meter indicator of the present utility model is for measuring the multi-functional magnetic survey transmitter that the magnetic field displacement is designed and developed.It changes into the magnetic field change in displacement by the servo-actuated magnet steel rotation of needle pivot, on needle pivot, fix a sensing magnetic steel sleeve, two sensing magnet steel are arranged above it, on its dead ahead wiring board, a Magnetic Sensor is arranged, thereby convert the variation in angular displacement of sensing magnet steel to electric signal, pass through digital filtering again, digital processing technologies such as software correction, with the MCU microprocessor is core, reaches the purpose of measuring the magnetic field change in displacement, and by duplicate rows liquid crystal display instantaneous delivery and integrated flux.
The condenser type angle transducer of the alternative present use of the utility model directly reduces cost 60%, and simplifies the mechanical assembly difficulty of indicator, saves the calibration time, improves measuring accuracy, increases reliability.Problem a little less than the signal that the magnetic signal that has well solved heavy caliber and chuck product in actual applications produces owing to distance has also solved because of decreased distance and magnet steel has been placed a baroque difficult problem of bringing outside the float.
