Abstract
The utility model relates to a device for rapidly detecting the faults of an instrument system, belonging to the technical field of detection for the faults of an instrument. The following technical scheme is adopted: the device comprises a body (1), a signal generator, connecting terminals (2) and output gears (3), wherein a plurality of the connecting terminals (2) are arranged on the body; a plurality of the output gears (3) are arranged above the connecting terminals; and the signal generator is arranged in the body, and connected with the connecting terminals and the output gears respectively. In order to rapidly detect whether the parts have faults, the device disclosed by the utility model is connected into an instrument detection system, and the fault parts can be rapidly and accurately judged by virtue of the standard signal provided by the signal generator of the device disclosed by the utility model. The device disclosed by the utility model has the active effects of being small in shape, simple in structure, easy to carry and strong in practicability; and the device can be used for rapidly and accurately judging the faults of the instrument system, and be used as a standard current signal generation device for correcting a measurement display system.
Description
Technical field
The utility model relates to a kind of device of the fast detecting instrument system failure, belongs to the sensor fault detection technical field.
Background technology
At present, the automaticity that enterprise produces is more and more higher, and the realization of robotization control, rely on the measuring instrument at numerous scenes.Most measuring instruments all are the measured data of primary transducer of collection site, become to send as 4-20 mA signal to be transferred to control system again.In actual production, can realize the robotization control of equipment, often depend on whether the work of spot sensor is normal, therefore when gauge sensor breaks down, can be fast, accurate inspection goes wrong very important.When the background technology measuring instrument breaks down, to check first primary element, reexamine to become and send element, reexamine receiving element, also will check display system at last, process is loaded down with trivial details, be difficult to reach rapidly, accurately, and the maintenance personal also needs to carry the multiple types of tools such as multimeter, signal generator, signal checking instrument, and especially for the abominable place of site environment, looking up the fault is very inconvenient.
The utility model content
The utility model purpose provides a kind of device of the fast detecting instrument system failure, and is simple in structure, easily carry, and can find out guilty culprit quickly and accurately, increases work efficiency, and solves the problems referred to above that background technology exists.
Technical solutions of the utility model are:
A kind of device of the fast detecting instrument system failure, comprise body, signal generator, connection terminal and output gear, at body a plurality of connection terminals are set, the top of connection terminal arranges a plurality of output gears, signal generator is arranged in the body, respectively with connection terminal be connected gear and be connected.
Described connection terminal quantity is four, applicable to two-wire system and four-wire system instrument connection.
Described output numbers of gear steps is three, 4-20 mA signal that can outputting standard, and three output gears are respectively 4mA output gear, 12 mA output gear and 20 mA output gear.
When instrument breaks down, show as demonstration undesired more, in order to check out instrument fault accurately and rapidly, use the utility model.In Examination system of instrument, what easily go wrong is instrument spot sensor, transmitter, junction box and signal collecting element, for going out these parts, fast detecting whether breaks down, the utility model is connected in the Examination system of instrument, utilize standard signal that the utility model signal generator provides can be fast, accurate failure judgement part.
The utility model good effect is: outward appearance is small and exquisite, and is simple in structure, easily carries, practical; Can judge fast and accurately the fault of instrument system, the utility model also can be used as the standard current signal generating means, is used for the calibration measurement display system.
Description of drawings
Fig. 1 is the utility model embodiment schematic diagram;
Fig. 2 is the utility model schematic top plan view;
Among the figure: body 1, connection terminal 2, output gear 3.
Embodiment
By the following examples, the utility model is described in further detail.
A kind of device of the fast detecting instrument system failure, comprise body 1, signal generator, connection terminal 2 and output gear 3, at body a plurality of connection terminals are set, the top of connection terminal arranges a plurality of output gears, number generator is arranged in the body, respectively with connection terminal be connected gear and be connected.In an embodiment, described connection terminal quantity is four, applicable to two-wire system and four-wire system instrument connection.Described output numbers of gear steps is three, 4-20 mA signal that can outputting standard, and three output gears are respectively 4mA output gear, 12 mA output gear and 20 mA output gear.
Using method: the utility model is directly connect on the line, replace instrument spot sensor element (for example: FIT, PT, TT, WT), if can show regime values at display terminal, just can be judged to be the gauge sensor element and have fault.If show to also have problem, will carry out next step inspection.The utility model is connected on the terminal of PLC switch board, if can show regime values at display terminal, then explanation has problem to Site Detection element or junction box's circuit; If can not normally show, illustrate that then the interior circuit of PLC switch board has problem or PLC to gather the I/O point problem is arranged, need to change.
Claims (3)
1. the device of a fast detecting instrument system failure, it is characterized in that comprising body (1), signal generator, connection terminal (2) and output gear (3), at body a plurality of connection terminals are set, the top of connection terminal arranges a plurality of output gears, number generator is arranged in the body, respectively with connection terminal be connected gear and be connected.
2. the device of described a kind of fast detector table system failure according to claim 1 is characterized in that described connection terminal quantity is four.
3. the device of described a kind of fast detector table system failure according to claim 1 and 2 is characterized in that described output numbers of gear steps is three, and three output gears are respectively 4mA output gear, 12 mA output gear and 20 mA output gear.
