1. A temperature monitoring system for an electric power-applied section, comprising:
- a temperature history recording means for measuring a temperature of said electric power-applied section and recording said temperature as a temperature history together with its measurement time; and
a control means for controlling the recording and a transmitting operation of said temperature history at a first predetermined interval,wherein said temperature history recording means comprises;
a temperature sensor that generates a temperature detection signal according to said temperature;
a memory that stores, as said temperature history, a measured temperature and a measurement time based on said temperature detection signal; and
a housing comprising a watertight circuit housing portion being formed to make a thermometric surface of said temperature sensor contact a measured object, wherein said memory comprises;
a history memory that stores, in a time series, said temperature history; and
a temperature alarm memory that stores, in a time series, as a temperature alarm, a temperature history being out of a range of a normal temperature, andwherein;
said control means controls said temperature history recording means to conduct a recording operation of the temperature history at a second predetermined time interval that is shorter than said first predetermined time interval when a temperature history is stored in said temperature alarm memory.

Abstract
A temperature monitor includes a temperature sensor, a transmitter, and a controller. The temperature sensor generates a temperature signal based upon a detected temperature and the controller controls the temperature sensor to generate the temperature signal and controls the transmitter to transmit the temperature signal along with a time at a first predetermined interval.

2. A temperature monitor comprising:
-
a temperature sensor that generates a temperature signal based upon a detected temperature; a transmitter; and a controller that controls the temperature sensor to generate said temperature signal and that controls said transmitter to transmit said temperature signal along with a time signal at a first predetermined interval, wherein said controller controls said transmitter to transmit said temperature signal and said time signal at a second predetermined time interval that is shorter than said first predetermined interval if said temperature signal indicates that said detected temperature is outside of a predetermined temperature range. - View Dependent Claims (3)
