Acrel ARTM-Pn Wireless Temperature Measuring Device For 3-35kV Indoor Switchgears
Product Introduction
ARTM-Pn wireless temperature measuring equipment has been developed in compliance with Specification for Wireless Temperature Measuring equipment, NB/T 42086-2016. It is suitable for 3-35kV indoor switchgears, including built-in switchgears, handcart switchgears, fixed switchgears and loop-net switchgears. It is also suitable for 0.4kV low-voltage switchgears such as fixed switchgears and drawer switchgears. The wireless temperature sensors can be installed at any heating point in switchgears, the device utilizes the wireless data transmission technology for real-time transmission of monitored temperature data and displays such data on ARTM-Pn locally. In addition, it can be networked via the RS485 port for remote intelligent monitoring.
