FIELD: machine building.
SUBSTANCE: device for calibrating sensors of gas concentration in route conditions in systems of cross-road main refers to pipeline transporting and can be used fro control of technical condition of mains at their crossing automobile and rail roads. The device consists a protective jacket with a vent pipe, of a plugged branch fastened on the vent pipe, of several sensors of leaks in the branch, and also, of pneumatic accumulator of gas mixture connected to the branch via a connecting pipe; additionally, there is installed a gate shutting off the output of the branch into the vent pipe and the second connecting pipe with a rubber hose connected to it via a valve. Internal volume of the pipeline is specified bigger or equal to internal volume of the branch.
EFFECT: qualitative reproduction of test input signal and upgraded accuracy of calibrating sensors under route conditions.
