Wireless temperature monitor sensor

ACREL wireless temperature sensor device is suitable for high and low voltage switchgear.


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.


It is usually installed in cable connection,circuit breaker contact,knife switch,middle connection of high voltage cable,dry transformer,low voltage heavy current and other devices. 


It can transmit data to the transceiver ATC450-C or ATC600 by wireless transmission frequency 470Mhz or 434Mhz.
