Product DescriptionProduct DescriptionE+H COS41In the intricate world of industrial process measurement and control, precision, reliability, and adaptability are crucial. Endress+Hauser, a globally recognized leader in process instrumentation, has once again demonstrated its engineering prowess with the introduction of the COS41 dissolved oxygen sensor. This state - of - the - art sensor has rapidly become an essential tool across a wide spectrum of industries, offering a unique combination of advanced technology, durable construction, and user - friendly features.The E+H COS41 is specifically designed to meet the most exacting requirements of industries such as water and wastewater treatment, food and beverage production, pharmaceutical manufacturing, and aquaculture. By leveraging cutting - edge engineering and decades of industry - leading experience, Endress+Hauser has created a product that stands out in the highly competitive industrial instrumentation market. Its ability to provide accurate and reliable dissolved oxygen measurements in diverse and often challenging process conditions makes it an invaluable asset for optimizing processes, ensuring product quality, and enhancing overall plant efficiency.1. Technical Specifications1.1 Measuring RangeThe COS41 offers a wide and flexible measuring range for dissolved oxygen. It can accurately measure dissolved oxygen concentrations from 0 to 20 mg/L, which covers the typical range of dissolved oxygen levels found in most industrial processes. This includes applications such as water treatment, where the dissolved oxygen level in raw water may vary from a few mg/L to around 10 mg/L, and in some biological processes, where higher dissolved oxygen concentrations may be required. For example, in an aquaculture system, maintaining the dissolved oxygen level between 5 - 8 mg/L is crucial for the health and growth of fish. The COS41 can precisely monitor these levels, ensuring optimal conditions for the aquatic organisms. In a wastewater treatment plant's aeration tank, the dissolved oxygen concentration needs to be carefully controlled between 1 - 4 mg/L for efficient biological treatment. 1.2 Process TemperatureThis sensor is engineered to operate within a significant process temperature range. It can handle process temperatures from - 5 °C to + 50 °C (23 °F to 122 °F). This wide temperature tolerance makes it suitable for applications where the process fluid may be cold, such as in refrigerated food processing or in winter - time water treatment, or relatively warm, like in some fermentation processes in the food and beverage or pharmaceutical industries. In a brewery, for instance, during the fermentation process, the temperature of the wort can range from around 15 °C to 30 °C. The COS41 can operate accurately within this temperature range, providing reliable dissolved oxygen measurements that are essential for controlling the fermentation process.1.3 Process PressureIn terms of process pressure, the COS41 exhibits good resilience. It can withstand process pressures up to 10 bar (145 psi). This pressure tolerance allows it to be installed in pipelines, tanks, or other process equipment where the fluid may be under pressure. In a water supply system, for example, the water may be under pressure as it is pumped through the distribution network. The COS41 can be installed in the pipelines to measure the dissolved oxygen content of the pressurized water, ensuring that the water quality meets the required standards. 2. Communication Capabilities2.1 Analog OutputThe COS41, when paired with a compatible transmitter (such as the Liquiline M CM42), is equipped with a standard 4 - 20 mA analog output. This analog output is a widely used interface in industrial applications, allowing the sensor - transmitter combination to communicate the measured dissolved oxygen value to other devices in the control system, such as programmable logic controllers (PLCs), distributed control systems (DCSs), or recorders. The 4 - 20 mA signal is proportional to the measured dissolved oxygen concentration, with 4 mA corresponding to the lower end of the measurement range (usually 0 mg/L) and 20 mA corresponding to the upper end (20 mg/L in the case of the COS41). This linear relationship between the current signal and the dissolved oxygen value makes it easy for other devices to interpret and process the data.2.2 Digital Communication ProtocolsIn addition to the analog output, the COS41 - transmitter combination supports several digital communication protocols, providing enhanced functionality and flexibility. One of the commonly supported protocols is HART (Highway Addressable Remote Transducer). HART communication enables two - way communication between the sensor - transmitter unit and a host system. It allows for the retrieval of additional information from the COS41, such as diagnostic data, sensor status, and calibration information. With HART, operators can remotely configure the sensor - transmitter, perform calibration, and receive real - time alerts if any issues are detected. For example, if the COS41's membrane starts to show signs of fouling, the HART - enabled system can send an alert to the operator, who can then take appropriate action such as scheduling a cleaning or replacement of the membrane.Another important digital communication protocol supported is Modbus. Modbus is a widely used serial communication protocol in industrial automation. It allows the COS41 - transmitter to communicate with other Modbus - compatible devices over a serial bus, such as RS - 485. Modbus communication offers fast and reliable data transfer, making it suitable for applications where multiple devices need to be interconnected in a network. In a large - scale industrial plant, the COS41 - transmitter can be integrated into a Modbus network along with other sensors.SpecificationMeasurement Range0–20 mg/L (standard), 0–50 mg/L (extended)Accuracy±1% of reading (0–20 mg/L)Response Time (T90)<30 sec (standard membrane)Temperature Range–20°C to +80°C (PP), –20°C to +130°C (PVDF)Pressure RatingUp to 6 bar (withstandable up to 10 bar briefly)Membrane TypesTeflons (standard), PTFE (high-temperature)MaterialsPP/PVDFElectrolyte life6–12 monthsCompany ProfileKeRui (WeiFang) Automation Equipment Co., Ltd. is specialized in industrialautomation instrument development, production and sales, technical servicesand supporting equipment supply of specialized companies.
