Air pressure detected value is sent to reception display device 102 by way of being wirelessly transferred；
Display device 102 is received, for receiving air pressure detected value and carrying out output display.
When being tested, pressure acquisition equipment is placed in tested low pressure test chamber, adjusts low pressure
Proof box gathers the air pressure detected value in tested low pressure test chamber, and passes through nothing to base measuring pressure point
The mode of line communication sends air pressure detected value to outside reception display device and is shown, it is to avoid make
Error is brought to airtight impacting with wire, effectively improve low pressure test chamber calibration accuracy and
Reliability.
Further, with reference to Fig. 2, pressure acquisition equipment 101 includes：
Pressure transducer 103, for gathering the air pressure detected value in tested low pressure test chamber；
Wireless sending module 104, for air pressure detected value is carried out wireless transmission；

Further, receiving display device 102 includes：
Wireless receiving module 106, for receiving the air pressure detected value；
Processor 107, for being processed and being exported the air pressure detected value；
Display module 108, for the air pressure detected value Jing after processor process is shown.
Pressure transducer 103 detects the air pressure in tested low pressure test chamber, and air pressure detected value is sent
To wireless sending module 104, wireless sending module 104 sends air pressure detected value to wireless receiving mould
Block 106, wireless receiving module 106 are retransmited to processor 107 and carry out data processing, after process
Air pressure detected value send to display module 108 and shown, tester can pass through display module
Intuitively see air pressure detected value, you can air pressure detected value and base measuring pressure are compared.
As one kind preferred embodiment, wireless sending module 106 is ZigBee sending modules,
Wireless receiving module is ZigBee receiver modules, carries out radio communication based on ZigBee, it is possible to achieve
75 meters to hundreds of meter of data transfer.
On the other hand, when the pressure box in prior art to there is pressure output interface is calibrated, its pressure
Power output interface is distant with its pressure display interface, and metrological personnel is in comparison calibration value and tested gas
As time irreversibility can produce certain error during pressure case indicating value, then may be used using Zigbee radio communications
Easily to move to equipment, site environment is adapted to.
Preferred embodiment display device 102 is received also including input module 109 as a kind of,
For obtaining the reference pressure value of outside input and sending to processor 107, processor 107 is additionally operable to
