Embodiment
Below in conjunction with drawings and Examples, the present invention is further described.
As Fig. 1, shown in Fig. 2, Automatic detection device for pressure sensor of the present invention, comprise monitor station 1, the controller 3 being positioned at the detecting unit 2 on monitor station 1 and being connected with detecting unit 2, described detecting unit 2 comprises shell 201, stem stem 202, coil 203, soft magnetism block 204 and back-moving spring 205, described coil 203 is arranged in shell 201, described stem stem 202 is through coil 203, and shell 201 is all extended in stem stem 202 top and the bottom, described soft magnetism block 204 is positioned at stem stem 202 top, described stem stem 202 top is through back-moving spring 205, described back-moving spring 205 is between soft magnetism block 204 and shell 201, described coil 203 is connected with controller 3.
The course of work of this Automatic detection device for pressure sensor is as follows:
First be placed on immediately below detecting unit 2 by pressure transducer to be detected, and be connected with controller 3 by testing pressure sensor, start-up connector 3 starts to detect.Controller 3 output current enters the coil 203 of detecting unit 2, the coil 203 of energising produces magnetic field, the soft magnetism block 204 being positioned at stem stem 202 top moves downward due to the effect of magnetic field force, thus drive stem stem 202 to move downward, the lower contacts pressure transducer of stem stem 202, and pressure is applied to it, if pressure transducer is working properly, correct signal will be transmitted to controller 3, after controller obtains this signal, stop powering to the coil 203 of detecting unit 2, magnetic field dissipate, soft magnetism block 204 moves upward under the effect of back-moving spring 205, stem stem 202 is driven to move upward, detecting unit restores to the original state, if pressure transducer breaks down, just cannot transmit correct signal to controller 3, controller 3 will keep the power supply to detecting unit 2, and the stem stem 202 of detecting unit 2 keeps pressed status always, and staff just can determine that this pressure transducer is defective accordingly.Wherein, described soft magnetism block 204 is made up of soft magnetic material, and after preventing the magnetic field dissipate of coil 203, soft magnetism block 204 also retains certain magnetic, acts on shell 201 or spring 205 and affects the accuracy of detection.
In such scheme, if a monitor station 1 is only arranged a detecting unit 2 obviously can affect detection efficiency, so, as monitor station described in optimal way 1 being provided with two or more detecting unit 2.So just can detect multiple pressure transducer simultaneously, thus increase work efficiency.
In such scheme, if pressure transducer that is direct by stem stem 202 and contact detection, damage may be caused to pressure transducer, so as optimal way, described stem stem 202 lower end is provided with footing 206, and described footing 206 bottom is provided with cushion 207.So just contacted by cushion 207 contact pressure sensor, also would not cause damage to pressure transducer.
In such scheme, because coil is often energized, can accelerate its oxidation, cause coil shortening in serviceable life, so as optimal way, described coil 203 outer wrap has diaphragm.So just can protect coil 203 to a certain extent, extension coil serviceable life.
In such scheme, the sidewall of shell 201 is actual just mainly bears supporting role, if 4 201, shell all has sidewall, material can be wasted undoubtedly, so as optimal way, described shell 201 comprises end face 2011, bottom surface 2012 and one or two supporting surfaces 2013.So not only save material, reduce costs, can also intensifier coil heat radiation, be convenient to check and more emat coil simultaneously.
