It extends to required length.Verification cover is fixed on metal hose upper end, and the length for adjusting telescopic rod as needed can give it
To area to be tested, gas sensor to be detected is placed in verification cover inside, verification cover is so that around to school gas sensor
A type semienclosed gas chamber is formed, for improving the response speed of test.By replacing different size of verification cover, can be adapted to
Different types of gas sensor.Verification cover is fabricated using injection molding die sinking, small in size, light-weight, via the biography of telescopic rod
It passs, can easily reach under the conditions of human body should not reach region, such as high-altitude, dell, hole etc., especially in the presence of unknown dangerous shape
Related sensor detection under condition etc..
In order to increase the reliability of the utility model, the probability of happening of failure in use is reduced, using inside without any
The mechanical retractable bar of electric circuit connection member and mechanical transmission component simplifies internal structure, makes every effort to simplify reliable.The bar of telescopic rod
Body uses light-weight, performance comparable metal carbon fibre material, Portable durable.
Using the gas flow sensor and high-precision proportion expression flow control valve of high sensitivity, with feedback control side
Formula carries out accurate control in real time to output flow, and the related design parameter of adjusting is shown that the OLDE on control handle is shown
In display screen, realize that the stabilization of output flow accurately controls, regulating and controlling digital is as it can be seen that system response quickly.
By connection by metal hose, metal hose top is equipped with the verification for detection sensor for verification cover and telescopic rod
Cover can arbitrarily adjust the direction of verification cover, Lai Shiying different location by adjusting the shape of metal hose in use
Sensor checksum test.
Verification cover can achieve the height for needing to verify and to school sensor position, Ci Zhonggao by operating telescopic rod
Position gas flow control detection instrument, which can be applied to dangerous, human body, should not reach the complicated field of gas detection such as region.
In conclusion telescopic rod of the utility model using high performance carbon fibre material, built-in spring spiral PU hose,
Gas circuit can be moved synchronously with the flexible of bar, and the sample gas for controlling flow is delivered to a high position or has certain risk people unsuitable
The place of entrance, to realize the flow control of high-order gas.
