BWY-803 (Amelioration) Series
Transformer Thermometer
    The BWY(WTYK)-802、803、802A、803A temperature controllers adopt the composite sensing technology which can output the signal of Pt 100 thermal resistance simultaneously while the temperature bulb pushes the elastic element. This signal can be transmitted to a control room more than hundreds of meters away. By the series XMT digital display thermometer, the temperature of transformer will be displayed and adjusted at the same time. The signal can also be translated to computer typical signal (0-5)V (1-5)V or (4-20) mA and communication port RS485 by a digital thermometer.

Main Technical Parameters:
    1、 Normal operating conditions: (-30~+55)℃
    2、 Measuring scope:-20℃~+80℃ 0~+100℃ 0~+120℃
    3、 Indicative accuracy: 1.5 grade
    4、 Control function:
     (1). Setting range: adjustable within the whole span
     (2). Setting accuracy: ±3℃
     (3). Switch difference: 6±2℃
     (4). Rated power of switch: AC 250V/3A
     (5)Standard set Point:
    802:K1=55℃; K2=80℃;
    803:K1=55℃; K2=65℃;K3=80℃
