It features enough sensitivity to expand the range of application into the ppm range. For instance fuels such as gasoline, diesel or kerosene are mixtures of hydrocarbons.Infrared gas detection theory of operationSome gases absorb light at a certain wavelength (colour). This absorption band is specific to the gas. The rate of the absorption depends not only on the substance to be detected but also on the number of gas molecules (i.e. the concentration of the gas). This premise is used to detect gases. For example, the C - H bond in hydrocarbon molecules will oscillate and absorb light at 3, 4 mm. This fact makes it so easy to detect fuels. Hexane, for instance has 14 C - H bonds compared to Methane that has only 4!A light beam is directed through a cuvette filled with the gas to be detected. The more hydrocarbons present, the more light will be absorbed. A photo detector at the other end of the cuvette measures the remaining light intensity. The difference between the original and remaining light intensity corresponds to the gas concentration.A reference beam with a different wavelength compensates for potential interferences of dust, humidity or variations of intensity from the light source.Fail-safe technologyFailure of important components such as the light source or photo detector will trigger a "system fail" alarm. Most local authorities will accept this as a self-diagnostic feature. Systems including a self-check require less maintenance and calibration, saving time and money.Simple maintenance: Easy to read display and non-Vintrusive calibrationThe bright LED display of the Statox 501 IR shows the gas concentration in percent L.E.L. (Lower Explosion Limit). An important accessory is the calibration adapter, featuring control buttons operating Hall-sensors inside the Ex d housing.The service menu is password protected preventing unauthorised access. All parameters can be checked and changed, or a calibration can be done all without opening the transmitter. The adapter is also equipped with a gas outlet so that it can be used for flow-through applications.Impervious compact designThe dimensions of the Statox 501 IR are small and compact. The sensor compartment is completely sealed, not allowing dust or insects to enter. It is located in the center of the sensor head. This allows heat radiation from the electronics and the infrared lamp to keep the unit a few degrees above the ambient temperature thus avoiding condensation. This innovative design makes any additional heating unnecessary, allowing the sensor head to be very energy efficient. This saves additional money by eliminating more expensive wiring and a bigger power supply that would otherwise be necessary.The sensor head is rated protection class IP 67 (6 = protection even against fine dust, 7 = submerged 1 m deep in water for 30 minutes). You can have confidence that this system will safely operate even in the harshest environment.产品更多信息在线甲烷监测仪 0-100%LELC7-Statox 501 IR黏泥含量监测仪型号:GSC10NN-II货号:GSC10NN-II型黏泥含量监测仪一、概述微生物黏泥会堵塞冷却水的通道，降低冷却水冷却效果，降低水质稳定剂的作用，引起金属设备的腐蚀。因此冷却水中微生物黏泥量的多少，直接反映了冷却水系统中微生物活动的情况和危害程度。测定微生物黏泥量是监测冷却水处理质量和微生物生长情况的主要方法之一。二、工作原理黏泥含量监测仪采用生物过滤网进行生物黏泥量的测定。其原理是让循环冷却水以一定的流速经转子流量计后，再通过生物过滤网，将生物过滤网搜集的黏泥移入量筒，测定黏泥的体积，并以1立方米冷却水中含有黏泥的体积表示黏泥量。三、技术参数1、电源：220V±5% 50Hz±5%2、消耗功率：50W3、定时范围：1分钟-9小时59分钟4、流速模拟范围：0-1.3m/s5、外形尺寸：55*35*656、重量：约35KG产品更多信息黏泥含量监测仪GSC10NN-II
