  • What are the troubleshooting methods for COD water quality online analyzer

    2025-08-06

    1、 Hardware troubleshooting 1. Optical system abnormality Phenomenon: Large data fluctuations, no readings or display of "optical path failure". Possible reasons: Optical window contamination (dust, oil stains, reagent crystallization). The light source (LED/xenon lamp) is aging or damaged. The sensitivity of photovoltaic cells (photodetectors) decreases. Troubleshooting steps: Clean optical window: Dip a dust-free cloth in ethanol and gently wipe to avoid scratching the surface. Check the intensity of the light source: Confirm the stability of the light source output through the device self-test function or an external optical power meter. Test the photovoltaic cell: block the light path and observe whether the signal changes as expected (if there is no change, it needs to be replaced). Case: A sewage treatment plant equipment had its optical window covered by algae, resulting in a COD reading that was 50% lower. After cleaning, it returned to normal. 2. Blockage in the flow system Phenomenon: Injection failure, unstable flow rate, or alarm of "flow path blockage". Possible reasons: Reagent crystallization (such as silver sulfate precipitation at low temperatures). Sedimentation of particulate matter (such as sediment and fibers) in water samples. Aging or impro...

  • Digital dissolved oxygen sensor application scenarios

    2025-08-06

    The digital dissolved oxygen sensor is widely used in scenarios that require real-time monitoring of dissolved oxygen concentration in water due to its high precision, fast response, strong anti-interference ability, and digital integration advantages. The following are typical application scenarios and specific case analysis: 1、 Aquaculture Core requirements Dissolved oxygen is a key parameter for respiration in aquatic organisms such as fish, shrimp, and crabs. Hypoxia can lead to suffocation, death, or growth retardation. Real time monitoring of dissolved oxygen in different water layers (such as pond bottoms and net cages) is required to avoid local hypoxia. Application Cases Factory based circular aquaculture: Multiple sensors are deployed in the aquaculture pool, combined with a PLC control system to automatically adjust the aerator and water flow rate, maintaining dissolved oxygen at 5-8mg/L (suitable range for fish). Pond aquaculture: Real time data is uploaded to a mobile app through buoy sensors, allowing farmers to remotely monitor changes in dissolved oxygen levels and activate oxygenation equipment in a timely manner during nighttime or rainy days. High density aquaculture: For example, in shrimp farming, dissolved oxygen levels below 3mg/L can trigger stress reactions, sensors ...

  • Composition of VOCs online monitoring system

    2025-08-06

    The VOCs online monitoring system usually consists of a sampling unit, a preprocessing unit, a gas analysis unit, a data acquisition and transmission unit, an auxiliary unit, and monitoring software. Each unit works together to achieve real-time monitoring and data management of VOCs. The following is a detailed introduction to each component: 1. Sampling unit: Sampling probe: responsible for collecting gas samples from flue gas or air, usually made of high temperature and corrosion-resistant materials such as stainless steel to ensure normal operation in harsh environments. The sampling probe has a filtering function, which can preliminarily filter the particles in the flue gas to prevent them from entering the subsequent equipment and causing blockage and damage. Heat tracing pipeline: Due to the tendency of VOCs to condense into liquid form or adsorb on the inner wall of the pipeline at room temperature, the function of the heat tracing pipeline is to maintain the temperature of the gas, keeping it in a gaseous state for easy transmission and measurement. Heat tracing pipelines generally use heating wires or heat tracing pipes to maintain a constant temperature through a temperature control system. 2. Preprocessing unit: Dust removal device: removes impurities such as particulate matter and ...

  • Technical principle of pressure transmitter

    2025-08-06

    A pressure transmitter is an industrial automation instrument that converts pressure signals into standard electrical signals (such as 4-20mA DC, 0-10V DC, or digital signals). Its technical principles can be summarized into four core links: pressure sensing, signal conversion, signal amplification and processing, output and transmission, as follows: 1、 Pressure sensing The core of a pressure transmitter is the sensor, which is responsible for directly sensing changes in external pressure. Common types of sensors include: Piezoresistive sensor: utilizing the piezoresistive effect of semiconductor or metal materials. When pressure is applied to the sensor diaphragm, the diaphragm undergoes deformation, causing a change in the internal resistance value. Convert resistance changes into voltage signals through a Wheatstone bridge. Capacitive sensor: composed of two parallel electrode plates. Pressure causes a change in the capacitance value between the diaphragm electrode and the fixed electrode, which is then converted into an electrical signal. Piezoelectric sensor: Utilizing the characteristic of piezoelectric materials (such as quartz crystals) generating charges under pressure, it outputs an electrical signal proportional to the pressure. This type of sensor is suitable for dynamic pressure me...
