Temperature measurement transmitter

Product Overview
The temperature measurement transmitter adopts a passive power supply design, and the temperature measurement component of the device is installed near the connection point where the current carrying conductor of the high-voltage switch is prone to temperature rise. Through wireless data transmission, the isolation transmission of temperature sensor signals installed at the high potential end to the low potential end instrument can be solved. For removable switchgear, simply install the sensor module on the handcart side, which is very convenient for installation, modification, and maintenance. The display instrument of the device is also equipped with an internal temperature sensor in the cabinet, which can display the relative temperature rise of the heating point. The application of this device provides an effective monitoring method for solving item 11.7 "Preventing Overheating of Current Carrying Circuit of Switchgear" in the "Eighteen Major Accidents Measures for Power Grid Corporation of China".
