1. A temperature compensated alarm system comprising:

  • an alarm sensor having a known temperature characteristic and operative to produce an electrical output signal representative of a desired parameter to be monitored;

    a temperature transducer operative to provide an electrical output signal representative of the ambient temperature in vicinity of the transducer;

    a plurality of selectively addressable storage registers containing data representative of alarm threshold limits applicable at specified ambient temperatures;

    an electronic processing module including;

    means for sampling said alarm sensor and temperature transducer output signals;

    means for addressing and accessing threshold data from at least one selected register of said plurality in response to said transducer output signal; and

    means for generating an alarm signal if said sensor output signal exceeds said threshold data from said at least one selected register.
