Pressure aggregate PSR / PAR

General Description:

Pressure aggregate is applied for generation of dry air with moderate overpressure for filling of waveguide line to ensure suitable climatic conditions inside waveguide line. The overpressure value can be adjusted programmable in the range 0 - 100 kPa. The aggregate is equipped with 2 membrane compressors having possibility to operate separately. Generation of dry air is ensured with help of 2 drying cylinders; these ones operate alternatively in a few hour cycles.  Constant overpressure value is provided on the base of pressure sensor and following regulation through switch-over of compressors. Pressure aggregate is designed in form of 19" mechanical module with module height 175 mm (4U).

Pressure aggregate can be delivered for built-in in radar system separately in the same version for PSR and PAR radars.

Advantageous features of pressure aggregate

• Compact structural design in form of 19" plug-in block
• Separate operation of built-in compressors
• Programmable adjustment of overpressure value
• Automatic regulation of overpressure value inside small tolerance range
• Universal structural solution for PSR /PAR  versions
• Possibility of variable mechanical design
