Explanation/Annotation:Manometric. Doubling. For controlling and control of pressure of gaseous and liquid media in stationary refrigerating plants.
Detailed model description:Controlled mediums: air, refigerants, oils and other environments, non-aggressive to copper alloys.
Low-pressure detector (ÄÍÄ) and sensor of high pressure (ÄÂÄ,
Affecting on one combined switching device and device of cable inlet, that serve for joining of outer electric circuits.
The settings scale of ÄÍÄ has numerical and the intermediate marks, ÄÂÄ - the fixed setting. The setting, on which is tunable over ÄÂÄ, is installed to device package.
Scale controlled return zone ÄÍÄ-èíôîðìàöèîííàÿ with marks of minimal and maximum values.
Settings limits, MPa: ÄÍÄ-îò - 0, 07 up to 0, 4, ÄÂÄ-îò 0, 6 up to 3.
Return zone, MPa: ÄÍÄ, ðåãóëèðóåìàÿ-îò 0, 04 up to 0, 25 (is directed in
Increase side relating to pressure setting); ÄÂÄ, non-controlled - not more than 0, 25 (is directed downwards relating to pressure setting).
Switching current on tension up to 380Â of alternating current by the frequency
