CLO2 sensor

 CLO2 chlorine dioxide sensor electrochemical gas sensor, an infrared gas sensors, catalytic combustion gas sensor output is small analog signal, the average user can not directly use these sensors, so Sheng Kaian technological research out of a relatively independent mini digital intelligence unit This unit 0-5V / 4-20mA signals and digital serial output to an analog signal. Smart sensors via test data transmission or reception instructions to achieve: calibration, drift and nonlinearity compensation, set the zero drift compensation parameters, check the parameter setting in the test data output. Smart sensors is greatly improved, first self-test self-diagnosis function when the power is turned on, the diagnostic tests to determine whether the fault module; secondly can be corrected according to the time line, the microprocessor within the calibrated EPROM presence data comparison proofreading. 4NE and 7NE series is designed for the new intelligent sensor gas detector manufacturer launched mainly to solve a wide range of gas detection, sensor incompatible varieties, production calibration of complex issues such as core parts replacement limit. Once the smart sensor, just developing a product, you can quickly respond to customer demand different type of gas detected, and the production process is simplified, without recalibration, dramatically reduces development costs, production costs, product quality is also immediately lift to world-class standards. Features: 1, patent standard interfaces, direct replacement of different types of sensors constitute 2 different types of detectors, intrinsically safe design, hot plug 3, professional selection, imported, compatible with infrared, electrochemical, catalytic, semiconductor, etc. a variety of sensors 4, comes with temperature compensation, precise factory calibration, when used without recalibration 5, while the output voltage and serial characteristics, enabling customers to debug and use; 6, the most simplified external circuit, producing simple, easy to operate Applications: Sensor Installation: intelligent gas sensor is designed with seven pins, a plug socket mounted on the sensor, in order to ensure reliable connection, should choose to use a dedicated jack. Jack should press pins arranged in a corresponding manner, the jack should be mounted vertically, welding firm. According to the special requirements of the user, can not use the pin plug mode, and an external lead the way, the line length is generally not more than 150mm. In non-hazardous areas and can be charged hot. In the proof requirements of the work site, before installation, you must turn off the power for the connected sensors.
