Abstract
The utility model provides a full-automatic pressure-verifying device, and the device comprises an automatic pressure controller, a gas source, a computer controller, a printer, and an instrument calibrating frame. The automatic pressure controller, the gas source and the instrument calibrating frame are connected through flexible pipes. Meanwhile, a to-be-verified instrument or a sensor is connected with the gas channel of the instrument calibrating frame, thereby forming a sealed gas channel. A computer, the automatic pressure controller and the to-be-verified instrument or sensor are in signal connection through serial ports. The computer controls the automatic pressure controller for remote control, and automatically collects the pressure values of the to-be-verified instrument or sensor under different pressures. After pressure verification, a calibration certificate is printed through the printer. The device greatly improves the automation and efficiency of verification.

Embodiment
Below in conjunction with drawings and Examples, the utility model is described in further detail, is to be noted that described embodiment is only intended to be convenient to understanding of the present utility model, and it is not played to any restriction effect.
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
As Figure 1-3, the full-automatic calibrating installation of pressure comprises automatic pressure controller, source of the gas, computer control, printer and instrument calibration frame, automatic pressure controller, source of the gas and instrument calibration frame connect by flexible pipe, be connected with the gas circuit of instrument calibration frame by test examination instrument or sensor, thereby form airtight gas circuit simultaneously; Computing machine, automatic pressure controller and carried out signal connection by serial ports by test examination instrument or sensor, by computer software, the pressure control sequence that user sets is installed, and according to the different pressure of pressure control sequence controlled pressure self-actuated controller, under different pressure, automatically gather by the pressure indicating value of test examination instrument or sensor, after pressure calibration finishes, user can be checked calibrating data and be printed calibration certificate by software.
The full-automatic calibrating installation of pressure can carry out Long-distance Control to automatic pressure controller by host computer (computer control system in figure), and the verification parameters such as calibrating spot pressure and pressure change rate are arranged, automatic pressure controller can be controlled set pressure point automatically according to parameter configuration.Automatic pressure controller is the core pressure control unit of equipment, is a set of autonomous device, can manually control, and also can pass through computer controlled automatic.The Output pressure of automatic pressure controller is connected to instrument calibration frame by gas circuit.Whole pressure calibration process is carried out Automatic Control by computing machine by program, and by multi-serial-port card gather the data of tested sensor and determine whether by vertification regulation qualified.Meter specially calibrating frame is according to user's request for utilization, can carry out respectively the calibrating of 8 instruments or sensor simultaneously.Meter specially calibrating frame is respectively every instrument provides independent AC220V power supply, standard RS232 communication interface and gas source interface and source of the gas plug.
When the conventional calibrating of pressure tool or sensor, adopt pressure controller to carry out pressure control, the tested indicating value of manual record is also carried out qualification determination; Along with the raising of instrument and meter automaticity, pressure controller, undertaken integratedly by software by test examination instrument or sensor and computing machine, form full-automatic calibrating installation, can greatly improve robotization and the efficiency of calibrating.
Describing is above only a specific embodiment of the present utility model, and obviously anyone modification of doing of this area or local replacement under the technical solution of the utility model instructs, all belong to the scope that the utility model claims limit.
