Product Introduction
The wireless temperature measurement host is mainly used in wireless temperature measurement systems as an intermediate device for data exchange between wireless temperature sensors and upper computers/servers. Generally, wireless temperature measurement is mainly targeted at high-voltage power distribution facilities. The disconnection contact points and cable joints of various devices may experience poor contact, looseness, insulation aging, arc impact, and other reasons during long-term operation, resulting in increased contact resistance and continuous temperature rise at the contact points, which affects the safe operation of the power system. The wireless temperature measurement system achieves real-time online monitoring of important node temperatures through temperature probes suitable for contact installation, wireless communication, and other technologies, helping to sense system anomalies faster and more sensitively.
The wireless temperature measurement host is compatible with various installation methods of wireless temperature sensors, using commonly used wireless communication frequency bands, making it easy to integrate into various intelligent monitoring and management platforms. The Yuxin wireless temperature measurement system is generally used in conjunction with the Yuxin intelligent power monitoring system. The same system solves various monitoring and management problems in power, and is compatible with energy consumption online monitoring and management functions. It is a high-quality tool for various low-voltage distribution and transformation power automation operations and maintenance.
Application scenarios
The wireless temperature measurement host is used in conjunction with the wireless temperature measurement sensor, usually installed near the sensor distribution location. Different application scenarios are equipped with different host configurations, and flexible matching can achieve good results. The wireless temperature measurement host can receive data from multiple wireless sensors and perform real-time dynamic display. Suitable for temperature monitoring of electrical contacts, busbars, cables, and other electrical contacts of high and low voltage equipment such as high and low voltage switchgear, transformers, etc. in industries such as power, steel, mining, and petrochemicals.
