摘要：
An activation indicator for a refrigeration system pressure relief valve is presented. In one embodiment, the indicator comprises a covering that covers an outlet passage of the pressure relief valve. The covering is at least partially displaceable by refrigerant as it exits the refrigeration system through the pressure relief valve. In another embodiment, sensors outputting a signal transmit an altered signal when the relief device releases refrigerant. A notification device is activated to indicate that the pressure relief device has activated.
