2. BWY-802，803型温控器主要技术指标：
■ 与BWY-802，803温控器的主要技术指标相同。
■ 输出Pt100铂电阻信号或4-20mA 电流信号
The BWY-802,803,802A,803A Temperature Controllers adopt the composite sensing technology which can output the signal of Pt100 thermal resistance simultaneously while the temperature bulb pushes the elastics element. The signal can be transmitted to a remote distance control room . By th series of XMT digital display indicators , the temperature of transformer will be displayed and adjusted at the same time.The signal can also be transmitted to computer typical signal (0~5) or (4~20) mA and communication port Rs 485 by a digitalcontroller.
