Low Side Pressure Limiter
Popular refrigerator and air conditioning safety device has a low level of side pressure limiter. The condensing unit cannot be overloaded if the low side pressure is maintained at a low level.
Low side pressure limiters consist of a pressure sensitive elements, such as a diaphragm or bellows. The item is placed in series with the capacitor unit chain. The circuit will be open if low pressure is higher than the required limit. Some low-pressure limiters act through the relay. Low pressure controls the relay. Relay in the controls electrical circuit...
