Claims (5)

1. Устройство для определения профилей концентрации жидких или газообразных веществ вдоль участка, в котором вдоль участка проложена линия (2), которая выполнена так, что вещества могут проникать внутрь ее, причем линия (2) заполнена испытуемой средой и столб испытуемой среды перемещается через линию (2) через временные промежутки и пропускается вдоль датчика (11), чувствительного относительно веществ, и причем между датчиком (11) и линией предусмотрено первое запирающее средство (10), отличающееся тем, что в линию (2) включено по меньшей мере второе запирающее средство (6), которое удерживает столб испытуемой среды в состоянии покоя в основном неподвижном.1. A device for determining the concentration profiles of liquid or gaseous substances along a section in which a line (2) is laid along the section so that the substances can penetrate inside it, and line (2) is filled with the test medium and the column of the test medium moves through the line (2) through time intervals and is passed along a sensor (11) sensitive to substances, and moreover, between the sensor (11) and the line, a first locking means (10) is provided, characterized in that at least a second e locking means (6), which holds the column of test medium at rest mostly stationary. 2. Устройство по п.1, отличающееся тем, что предусмотрено оборудование (8, 9), которое отрывает второе запирающее средство (6) при превышении или понижении ниже спадающего в линии (2) порогового значения давления. 2. The device according to claim 1, characterized in that equipment (8, 9) is provided, which tears off the second locking means (6) when the threshold pressure value decreases or falls below the threshold value that decreases in the line (2). 3. Устройство по п.2, отличающееся тем, что оборудование (9) содержит хронирующую схему, посредством которой второе запирающее средство (6) является автоматически запираемым после установленного времени. 3. The device according to claim 2, characterized in that the equipment (9) contains a timing circuit whereby the second locking means (6) is automatically locked after a set time. 4. Устройство по любому из пп.2 или 3, отличающееся тем, что оборудование (9) содержит находящийся в соединении с линией (2) манометрический выключатель (8), который при превышении или понижении ниже порогового значения давления предоставляет в распоряжение управляющий сигнал. 4. A device according to any one of claims 2 or 3, characterized in that the equipment (9) comprises a pressure switch (8) connected to the line (2), which, when the pressure is exceeded or decreased below the threshold pressure value, provides a control signal. 5. Устройство по любому из пп.2 - 4, отличающееся тем, что оборудование (9) содержит управляющую электронику (9), которая при приложении поставляемого манометрическим выключателем (8) управляющего сигнала, открывает второе запирающее средство (6). 5. A device according to any one of claims 2 to 4, characterized in that the equipment (9) contains control electronics (9), which, when the control signal supplied by the pressure switch (8) is applied, opens the second locking means (6).
