Application and Installation
Application
Wireless temperature monitoring system is prevents potential safety hazards caused by overheating of the contact resistance caused by oxidation, looseness, dust, and other factors during operation, improves equipment safety, timely, continuously, and accurately reflects the operating status of the equipment, and reduces the accident rate of the equipment.
Features
ARTM-Pn wireless temperature measuring equipment is installed with the front panel embedded. First, make a square hole on the switchgear surface to the specified size. Then, separate the two brackets from device and embed the device into the square hole. Finally, push and lock the brackets.
Transformer internal temperature monitoring
Factors such as transformer iron loss, copper loss, short circuit between coil turns, and poor air circulation in the installation site can cause the temperature of the transformer to rise abnormally, resulting in a shortened service life of the transformer. In severe cases, the transformer may even be burned.
From a safety perspective, it is recommended to use a wired temperature measurement solution. It is recommended to embed PT100 in the transformer and connect the PT100 to the ARTM-8L display device for temperature collection and display.

Motor internal temperature monitoring
Due to abnormal vibration of the motor or winding short circuit, turn-to-turn short circuit,
phase-to-phase short circuit and other factors, the motor causes internal heating, leading to serious
accidents such as motor burnout.
