- In detail
KP-3 and KP-6 cranes switches are intended for serial connection of one draft gage (various types) with three or six pulse lines bringing pressure (pressure) or discharge (draft) from three or six places of measurement of pressure of discharge. Cranes switches can also will be used to various schemes of switchings at operation of devices.
The crane works when switching of the measured environments which are not operating on brass.
Pressure or discharge which is subject to measurement from the bringing lines comes to a tube, passes through the channel in the case of the crane and further through a hollow stopper and other channel in the case comes to the tube connected to the device.
At installation of the index by means of a flywheel against one of scale marks one bringing line is connected to the device, all other bringing lines are blocked.
At installation of the index against the mark "0" the cavity of the case is reported with the atmosphere, in this provision of the index checking of the device on the zero provision of an arrow is made.
At installation of the index against the mark "Device" all bringing lines are blocked. Tightness of the device and the connecting line is in such a way checked.
The crane switch is tested manufacturer under pressure 250mm.rt.st. within 10 min., recession of pressure on 5mm.rt.st is allowed. The case of the crane allows installation only on the board panel.
Connection of the crane to pulse lines and to the device is made by rubber tubes.
