有毒气体传感/发送器 MSA公司的有毒气体传感/发送器是检测有毒气体,包括氯气、氰化氢、氧化硫的专用仪器,并向多测点监测设备传输4～20毫安的信号电流。这种传感发送器的组成是:微型隔膜泵,流量计、与4～20毫安接收器电气连接的电化学传感器。空气试样进入气室,经透气隔膜扩散,进入传感器组件的试样区。在此组件中氰化氢和氧化硫发生电氧化或经电化学作用减少
Toxic Gas Sensing / Transmitter MSA’s Toxic Gas Sensing / Transmitter is a dedicated instrument for the detection of toxic gases, including chlorine, hydrogen cyanide, sulfur oxides and transmits signals of 4-20 mA to multiple monitoring points Current. The sensor transmitter consists of a miniature diaphragm pump, a flow meter, and an electrochemical sensor electrically connected to a 4-20 mA receiver. The air sample enters the air chamber and diffuses through the air-permeable membrane into the sample area of the sensor assembly. Hydrogen cyanide and sulfur oxide are electrically oxidized or electrochemically reduced in this module
