Temperature measurement data obtained by measuring the temperature of a cable clamp () by a temperature sensor () is radio-transmitted from a temperature sensing unit () at a predetermined timing, and the radio-transmitted temperature measurement data is received by a receiving station (), classified by the temperature sensing unit number, and stored in a temperature measurement data storage area (A). The temperature measurement data transmitted from twelve temperature sensing units () can be received by one receiving station ().

Temperature monitoring device

A temperature recorder capable of storing, in time sequence, measured temperatures and measured times as temperature records in a memory incorporated therein, wherein, the temperature recorder is installed in a power line for temperature recording and, when the power line supplies a power in a normal temperature range, wirelessly transmits the temperature record to a monitor at a frequency of once every half day and, when an abnormal heating is detected from the power line, wirelessly transmits the temperature record as a temperature alarm record.

Temperature recorder and temperature recording and controlling system for power supply equipment

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.

Temperature monitor for electro-mechanical part

Data is transmitted to a main control device via sensing means such as temperature sensors, each having a memory means in which the ID code is stored, and via transmitting/receiving means such as switching elements. There is a stand-by period in the operation of the main control device after the main control device issues a command to start a sensing operation until the main control device issues a command to perform a read operation. The main control device receives power through a signal line the voltage of which is kept at a high level during the stand-by period. Thus, an equipment sensing system and an equipment control device which enable reliable and quick sensing, cost reduction, smooth control, and simplified wiring are provided.
