D220A-13 dual pressure sensor-switch is intended for use in automatic and automated control systems, control and regulation of pressures: in general industrial, stationary, refrigeration machines on freons D220-11, D220-12, D220R-11, in ship refrigeration machines on freons (device D220R-11), in general industrial stationary ammonia refrigerating machines, devices D220A-12, D220AR-12, D220A13, D220AR13, in ship ammonia refrigerating machines, devices D220AR12, D220AR13 D220A-13 principle of action The principle of operation of devices is based on pressure balancing on the bellows. Forces of elastic deformations of springs and bellows. The devices have two sensors - a low pressure sensor and a high pressure sensor acting on one common switching device. Low pressure sensor D220A-13 provides operation (switching contacts) when the controlled pressure drops to the set value and returns to its original position (reverse action) when the controlled pressure rises by the value of the dead zone. The D220A-13 high pressure sensor provides operation (switching of contacts) when the controlled pressure rises to the set value and returns to its original position (reverse action) when the controlled pressure drops by the value of the dead zone.
