Technical Parameters
Number of Input Channels: It usually has multiple analog input channels (the specific number needs to refer to the product manual), and can simultaneously collect multiple channels of analog signals, improving the collection efficiency of the system.
Input Range: Taking the common 4-20mA current input as an example, the measurement accuracy may reach ±0.1% FS (full scale); when the input is 0-10V voltage, the accuracy can also be maintained at a relatively high level.
Sampling Period: The sampling period is relatively short. For example, it may be within dozens of milliseconds to ensure that it can quickly capture the changes of analog signals.
Isolation Performance: It has good electrical isolation performance, which can effectively isolate external interference signals and protect the stability and safety of the system. Generally, the isolation voltage can reach 1500VAC or higher.
Operating Temperature Range: It can work stably within a certain temperature range. The common operating temperature range is from -10°C to 55°C to adapt to different industrial environments.
Application Fields
Petrochemical Industry: It is used to monitor and control various parameters in the petrochemical production process, such as the pressure, flow rate, and temperature in pipelines, and the liquid level and composition in reactors, etc. It ensures the safe and stable operation of the production process and improves product quality and production efficiency.
Power Industry: In power plants, it can collect the operating parameters of equipment such as generators and transformers, such as voltage, current, power, etc., to achieve real-time monitoring and control of the power system and ensure the stable and reliable power supply.
Metallurgical Industry: It is suitable for the measurement and control of parameters in the metallurgical production process, such as the temperature and pressure of blast furnaces, and the speed and tension of rolling mills, etc. It helps to optimize the production process and improve product quality and production efficiency.
Pharmaceutical Industry: In pharmaceutical production, it accurately measures and controls environmental parameters such as temperature, humidity, and pressure during the production process, as well as the flow rate and concentration of various materials, etc., to meet the strict requirements of the pharmaceutical industry for the production environment and process control.
The Yokogawa SC42-SP34 is a conductivity sensor produced by Yokogawa Electric Corporation and can be applied in the following scenarios:
Pharmaceutical Industry: During the pharmaceutical production process, it monitors the conductivity of purified water, water for injection, etc. to ensure that the water quality meets the quality standards for pharmaceutical production. For example, in the water system of a pharmaceutical factory, by installing the SC42-SP34 sensor, the conductivity changes of water can be monitored in real time, and water quality abnormalities can be detected in a timely manner to ensure the safety and stability of pharmaceutical production.
Chemical Industry: It is used to measure the conductivity of various solutions in the chemical production process, such as acid-base solutions, salt solutions, etc., to monitor the reaction process and control the solution concentration, etc. For example, in an electrolytic cell, by monitoring the conductivity of the electrolyte, the compositional changes of the electrolyte can be understood, and the electrolysis process parameters can be adjusted in a timely manner to improve production efficiency and product quality.
Power Industry: In the water treatment system of a power plant, it monitors the conductivity of make-up water, condensed water, etc. to help determine the purity of the water quality and prevent problems such as equipment corrosion and scaling caused by impurities in the water, ensuring the normal operation of power generation equipment. For example, in the make-up water system of a steam generator, the SC42-SP34 sensor is used to monitor the conductivity to ensure the quality of the make-up water and avoid damage to the steam generator.
Food and Beverage Industry: It detects the conductivity of water and raw material solutions in the production process, which helps to control the quality and stability of products. For example, in beverage production, the conductivity of syrup is monitored to ensure that the concentration of the syrup meets the formulation requirements, thereby ensuring the consistency of the taste and quality of the beverage.
