Изобретение относитс  к контрольно-измерительной технике, в частности к предохранительным устройствам дл  датчиков давлени .The invention relates to instrumentation engineering, in particular to safety devices for pressure sensors.

Известны устройства дл  заошты чувствительного элемента датчиков давлени  от перегрузочных давлений, содержащие корпус с отверсти ми дл  подвод щей и отвод щей магистралей, в котором размещена мембрана, св за на  с клапанным устройством ij , 2JDevices are known for sealing the sensing element of pressure sensors against overloading pressures, comprising a housing with openings for supply and discharge lines in which the membrane is placed, connected to the valve device ij, 2J

Известно устройство дл  предохранени  чувствительного элемента гидростатического высотомера от воздействи  давлени  больше допустимого з.A device is known for protecting the sensitive element of a hydrostatic altimeter from the effect of a pressure greater than permissible 3.

Известны гидростатические нивелиры с манометрическими датчиками, снабженные устройствами с кранами дл  защиты чувствительного элемента манометра от гидравлических ударов 4jKnown hydrostatic levels with manometric sensors, equipped with devices with taps to protect the sensitive element of the manometer from hydraulic shocks 4j

Ближайшим по технической сущности и достигаемому результату к предлагаемому  вл етс  предохранительное устройство дл  манометров, содержащее корпус с входным и выходным каналами , разделенный на две полости двум  эластичными мембранами различной эффективной площади с жестко закрепленным на них клапаном, перекрывающим отверстие, соедин ющее корпусThe closest in technical essence and the achieved result to the proposed is a safety device for pressure gauges, comprising a housing with inlet and outlet channels, divided into two cavities by two elastic membranes of different effective area with a valve fixedly fixed on them that connects the housing

с датчиком давлени , и перепускной канал, соедин ющий между собой полости корпуса 5 . Предохранительное устройство позвол ет перекрывать канал давлени  манометра при резком повышении давлени .with a pressure sensor, and an overflow channel connecting the cavities of the housing 5. A safety device allows to block the pressure channel of the pressure gauge with a sharp increase in pressure.

Однако при колебани х давлени , вызываемых воздействием динамических нагрузок на гидростатический нивелир (например встр хивание шланга при уклсшке его в процессе измерений и т.п.), указанные выше устройства не позвол ют перекрывать канал давлени  при резком понижении давлени , что может вывести датчик из стро .However, with pressure fluctuations caused by dynamic loads acting on a hydrostatic level (for example, shaking the hose while it is being measured during the measurements, etc.), the above devices do not allow the pressure channel to shut off when the pressure drops sharply, which can take the sensor out of build

Цель изобретени  - повьпиение надежности и предохранени  датчика давлени  от недопустимых резких разнонаправленных колебаний давлени  при использовании его в гидростатическом нивелире.The purpose of the invention is to increase the reliability and protection of the pressure sensor from unacceptable sharp multidirectional pressure fluctuations when used in a hydrostatic level.

Цель достигаетс  тем, что предохранительное устройство, устанавливаемое перед датчиком давлени  гидростатического нивелира, и содержащее, корпус с входным и выходным каналами , разделенный на две полости эластичной мембраной с закрепленным на ней клапаном, перекрывающим отверстие , соедин ющее корпус с датчикомThe goal is achieved by the fact that a safety device installed in front of a hydrostatic level pressure sensor, and containing a housing with inlet and outlet channels, is divided into two cavities by an elastic membrane with a valve fixed on it, blocking the opening, connecting the housing with the sensor
