The main differences between the BWY-803A and BWY-803ATH models are their environments and functional characteristics:

1. Applicable environment

  • BWY-803A: For transformer temperature monitoring under general environmental conditions.
  • BWY-803ATH: In addition to applying to the general environment, it is also particularly suitable for the humid and hot zone environment, and its exposed parts have anti-mold performance, which is in line with the standard of constant humidity and heat test.

2. Functional Features

  • BWY-803A::
    • Synchronized output of Pt100 RTD signals using composite sensor technology.
    • The temperature signal can be transmitted to the control room hundreds of meters away, and the transformer oil temperature can be synchronously displayed and controlled by the digital display temperature controller.
    • The setting range is full scale, the setting accuracy is ±3℃, and the switching difference is 4~8℃.
    • For controlling the startup, shutdown and signaling alarm of the transformer cooling system.
  • BWY-803ATH::
    • In addition to all the functions of the BWY-803A, it also adds adaptability to humid and hot zone environments.
    • It also utilizes composite sensor technology and can output a Pt100 RTD signal.
    • It has good protection performance and can work normally under outdoor conditions for a long time.

3. Other features

  • BWY-803A::
    • Measurement range is 0~100℃, 0~120℃ or 0~150℃.
    • Indication accuracy is 1.5 levels.
    • Protection class IP55.
  • BWY-803ATH::
    • Measuring range and indication accuracy are the same as BWY-803A.
    • The protection class is also IP55.

summarize

  • BWY-803A More suitable for use in general environmental conditions, with basic temperature monitoring and control functions.
  • BWY-803ATH Based on BWY-803A, the adaptability to humid and hot zone environment has been added, which is more suitable for use in humid or high humidity environments.
If your environment is humid or you need to use it outdoors for a long period of time, it is recommended that you choose the BWY-803ATH model.
