1.1 Product Introduction
ATE series wireless temperature measuring sensor 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. In addition, it can be transmitted to display device or remote intelligent monitoring
system.

If the sensor is ATE100M/ATE100/ATE200/ATE400/ATE100P/ATE200P, the number behind “组号： ”
should be same as number underlined in “*51809190240001*”, the sequence of installation is base on the
label, “编码：1A” is first one on the phase A, “编码：1B” is first one on the phase B，and so on.
Notice: wireless temperature sensors and display device in the package have been matched
before delivery. Do not use them with other display device or other wireless temperature sensors
together. Please installing them with label on the sensor.

According to the above pictures, If the sensor is ATE100M/100/200/400/100P/200P, the group
number of ATE must be same with the group number of ATC450-C/ATC600 and the installation order is
base on the label. The code of each sensor is used to distingguish each sensor from same group. “code:
001”is recommended to be installed on the first temperature measuring point of the first cabinet, and then
installed other sensors in this order.
In case of any special situation, please contact the relevant engineers for communication.
1.4.3 Installation Method

Firstly, take 2 pieces of alloy chips through the mounting hole of metal hasp, meanwhile fold the alloy
chips and fix the metal hasp in the middle of alloy chips. Secondly, take the folded alloy chips through one
silicone gasket, the core of ATE400 and another silicone gasket in turn.Thirdly, circle the whole alloy chips
around the mounting position and tension the alloy chips, then tighten the screw on the metal hasp. Finally,
subtract the excess alloy chips. The complete installation process is shown in Figures 1 to 4.
The wireless temperature sensor called ATE400 installation examples, see images below.
