In the disclosed embodiment, the sensing means is mounted in the access door of the refrigeration apparatus and the temperature sensors are mounted within a single housing. The sensor for sensing the ambient temperature is effectively insulated from the refrigerated space and senses the ambient temperature through a portion of the housing and door. In the illustrated embodiment, the sensing means is used to provide an ambient temperature compensated over-temperature alarm for the refrigeration apparatus.Field of SearchWITH INDICATOR OR TESTEROperatively correlated with automatic control Diverse function indicators or testers Atmospheric condensation accumulation, e.g., frost Condition sensing External cooled material Single refrigeration producer controlled by plural sensors Compensating or modifying External condition sensor Single sensor mounted or formed to respond to plural conditions, e.g., compensators By temperature | |
