1.Product Introduction of Wireless Temperature Measuring Host
Traditional temperature measurement methods often prove ineffective when faced with challenges such as high voltage, large current, strong magnetic fields, and spatial limitations. The OMARA wireless temperature measuring host works in conjunction with wireless temperature sensors. It uses radio waves to transmit signals, and there is no electrical connection between the sensors and the host, successfully solving the problem of the difficulty in real-time online monitoring of the operating temperature of the connection points of high-voltage equipment.
This wireless temperature measuring host is powerful and comprehensive, integrating functions such as monitoring the working status of temperature sensors, displaying on-site temperature, providing alarm prompts and outputs, recording events, and recording data. It can be widely applied in various scenarios of high-voltage electrical equipment, such as transformers and switchgear in substations, motors and busbar joints in power plants, as well as high-voltage distribution rooms in industrial plants. By operating in a networked manner through standard communication interfaces and working in conjunction with the upper computer software, it can provide accurate data support for the maintenance of high-voltage equipment, achieve predictive maintenance for thermal failures, effectively reduce the risk of equipment failures, and ensure the stable operation of the power system.
