Description
1. Real – world Case
In a large – scale water treatment plant, the MPRC086444 – 003 was integrated into the chemical dosing control system. The plant was responsible for treating a significant volume of raw water from a nearby river to make it suitable for domestic and industrial use.
One day, the water quality sensors detected a sudden increase in the level of contaminants in the incoming water due to heavy rainfall upstream, which had washed a large amount of sediment and pollutants into the river. The MPRC086444 – 003, which was connected to these sensors and the chemical dosing pumps, immediately received the data.
It quickly analyzed the new water quality parameters and compared them with the pre – set treatment requirements. Based on the analysis, the MPRC086444 – 003 adjusted the operation of the chemical dosing pumps. It increased the dosage of coagulants and disinfectants to ensure effective removal of the contaminants.
As a result, the water treatment process was able to adapt to the changing water quality, and the treated water still met the strict quality standards. This prevented potential water – borne disease outbreaks and ensured a continuous supply of clean water to the community.
2. Applications
- Water and Wastewater Treatment: As shown in the above case, it is used for controlling the dosing of chemicals such as coagulants, flocculants, and disinfectants. It can also be used to monitor and control other aspects of the treatment process, like pH adjustment and filtration.
- Industrial Process Control: In chemical manufacturing plants, the MPRC086444 – 003 can be used to control the addition of raw materials and catalysts in chemical reactions. It helps to ensure the correct stoichiometry and reaction conditions, improving product quality and yield.
- Food and Beverage Industry: For food and beverage production, it can be used to control the addition of ingredients such as preservatives, flavorings, and colorants. It ensures the consistency and safety of the products.
3. Weight and Dimensions
- Weight: The MPRC086444 – 003 weighs approximately 1.3 kg. This weight is relatively manageable, making it easy to handle during installation and maintenance.
- Dimensions: It has dimensions of about 190 mm in length, 140 mm in width, and 55 mm in height. These compact dimensions allow it to be easily installed in standard 19 – inch racks or control cabinets, saving space in control rooms.
4. Features
- Precise Control: The MPRC086444 – 003 offers precise control over the dosing process. It can accurately adjust the flow rate and dosage of chemicals based on real – time sensor data, ensuring optimal treatment results.
- Multiple Sensor Inputs: It can be connected to a variety of sensors, such as pH sensors, turbidity sensors, and flow sensors. This allows it to gather comprehensive information about the process and make informed control decisions.
- User – Friendly Interface: It has a user – friendly interface that enables operators to easily configure the dosing parameters, view the process data, and set up alarms. This simplifies the operation and management of the dosing system.
5. Stability and Reliability
- Robust Design: The MPRC086444 – 003 is built with a durable housing that provides protection against dust, moisture, and mechanical vibrations. This makes it suitable for use in harsh industrial environments, such as water treatment plants with high humidity and chemical exposure.
- Redundant Components: Some models of the MPRC086444 – 003 may have redundant power supplies and communication modules. In case of a component failure, the redundant part can take over immediately, ensuring continuous operation of the device and minimizing system downtime.
- Error – Detection and Self – Recovery: It has built – in error – detection mechanisms that can detect and diagnose faults in real – time. It can also perform self – recovery operations, such as restarting a malfunctioning module or switching to a backup control strategy, to maintain system stability.
6. Parameter Specifications
- Power Supply: It operates on a 24V DC power supply, with an allowable voltage range of 21.6V to 26.4V. This wide voltage range ensures stable operation even in the presence of small power fluctuations.
- Input/Output Channels:
- Analog Inputs: It has 6 analog input channels, which can accept signals from various sensors in the range of 0 – 10V or 4 – 20mA.
- Digital Inputs/Outputs: There are 10 digital input channels for detecting the status of switches and other digital sensors, and 8 digital output channels for controlling relays, solenoid valves, and other digital devices.
- Communication Interface: It supports communication via Modbus RTU over RS – 485, which is a widely used industrial communication protocol. This allows it to communicate with other devices in the control network, such as programmable logic controllers (PLCs) and human – machine interfaces (HMIs).
- Dosing Accuracy: The dosing accuracy is up to ±0.5% of the set dosage, ensuring precise chemical addition in the treatment process.
