Overview

        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.

Installation

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.

    Note: ATE400 can be installed with fixed contact, copper plate and cable head; If it is necessary to install moving contacts, it is necessary to consider the height of plum blossom head and sleeve is sufficient. 

FAQ

1. Is there any signal interference if more than 40 ACREL units are installed? 

Reply: No.

2. How to determine the ID of each sensor which is more than 40 units? 

Reply: Every sensor sends the temperature data and its ID to ATC600, then transmits to ATP display screen and IOT platform.

ATP dispaly screen and IOT platform can display the data and position of every sensor. The user can identify them easily.

3. How to make sure the battery can last up to 5 years? 

Reply: 5 years is the theoretical value calculated by the average current of the sensor. In actual use, it will be affected by various external factors, for example, the battery life will be greatly shortened under the condition of high temperature for a long time. 

4. If the battery runs out in less than 1 year, what is the solution? 如果电池在1年内损坏或者电量耗尽，该怎么处理？

Reply: There are 2 solutions:

1. The batteries in the ATE and AHE sensors can be replaced by new ones.

For ATE100M/200/200P, the Battery model is ER2450T.

You have to welding the two points in the sensor when you change their batteries.

For ATE400, it is strap mounted type, powered through electro-magnetic induction, it has no battery.

For AHE100, its battery model is CR2450, the sensor has battery holder, so the battery is easier to be replaced.

2. We can send new sensors to replace those ones with quality problems.

5. Ensure the receiver's ability to read how many sensor units? 

Reply: One ATC600-C can read the data of 240 sensors at most.

One ARTM-Pn can read the data of 60 sensors at most.

6. The current condition is that there are 4 receivers that will be installed, to ensure communication between receivers is not disrupted, for example: receiver 1 must read sensors in building 1, but sensors in building 2 are also read? 

Reply: Every transceiver will only display the data of the sensors with the corresponding group number, and even if it receives data from other groups of sensors, it does not matter because each sensor has a unique ID and does not cause confusion. 

7. What spare parts are available for the spare sensor unit? 

Reply: Transceiver has antenna, connection terminals, ATE400 comes with alloy plate, non-slip pad, locking piece and screws. 

8. How to distinguish AHE100 and ATE100M/ATE200 type sensor ID? is it enough with 1 receiver? 

Reply: The answer is the same with that of the 2^nd question.

Yes, it is enough with 1 receiver.

9. Do i have to send commands to the sensor for getting its temperature readings or it keeps sending temperature data automatically when connected?

Reply: ATE400 sensor monitor the data and uploaded it to ATC600 and IOT every 15 S.

ATE400 monitor tenperature and transmits the data every 15 s, it has nothing to do with temperature fluctuationi.

ATE100/200 and AHE100 measure the temperature every 25S. If the temperature changes more than 4 degrees from the previous temperature, the data will be uploaded to ATC600 and IOT. If the temperature changes less than 4 degrees, the temperature will be uploaded every 5 minutes.

if the temperature fluctuation is less than 4 ℃, is transmits every 5 minutes; if it is large than 4 ℃， it transmits every 25 s.

10. How I should interpret the data when I connect the ATC600 directly to the PC (though RS485)? For example, how I identify each sensor with their respective temp?

Register addresses and sensor codes correspond sequentially, one to one
