Product DescriptionProduct Description Rosemount Wireless 248 Temperature TransmitterIn the ever-evolving landscape of industrial automation, the demand for reliable, efficient, and flexible temperature measurement solutions has never been higher. Temperature is a critical process variable in numerous industries, including oil and gas, chemical, pharmaceutical, food and beverage, and power generation. Accurate and real-time temperature monitoring is essential for ensuring process safety, optimizing operational efficiency, maintaining product quality, and complying with strict industry regulations.The Rosemount Wireless 248 Temperature Transmitter, developed by Emerson Electric Co., a global leader in industrial automation technologies, stands out as a cutting-edge solution designed to meet these diverse and demanding requirements. Combining advanced sensor technology, robust wireless communication capabilities, and intelligent features, the Rosemount 248 has redefined the standards for wireless temperature measurement in industrial settings. 1. Product Overview and Design Philosophy1.1 Basic Definition and PurposeThe Rosemount Wireless 248 Temperature Transmitter is a battery-powered, wireless device specifically engineered to measure temperature in industrial processes and transmit the collected data to a central control system or monitoring platform. Unlike traditional wired temperature transmitters that require complex and costly cabling infrastructure, the wireless design of the Rosemount 248 offers unprecedented flexibility in installation, enabling deployment in remote, hard-to-reach, or hazardous locations where wired solutions are impractical or unsafe.The primary purpose of the Rosemount 248 is to provide accurate, stable, and continuous temperature measurements across a wide range of process conditions. It converts the analog signal from a connected temperature sensor (such as RTDs, thermocouples, or resistance sensors) into a digital signal, which is then transmitted wirelessly using industry-standard communication protocols. 1.2 Design PrinciplesThe design of the Rosemount Wireless 248 Temperature Transmitter is guided by several key principles that ensure its reliability, performance, and adaptability in industrial environments.First and foremost is the principle of robustness and durability. Industrial settings are often characterized by harsh conditions, including extreme temperatures, high humidity, vibration, corrosion, and exposure to dust, dirt, and chemicals. The Rosemount 248 is built to withstand these challenges, with a rugged housing constructed from high-quality materials such as stainless steel or reinforced plastic. It meets stringent industry standards for environmental protection, including IP66/IP67 ratings for ingress protection, and is certified for use in hazardous areas (e.g., ATEX, IECEx, CSA) to ensure safety in explosive atmospheres.Second is the principle of accuracy and precision. Temperature measurement accuracy is critical in industrial processes, as even small deviations can lead to product defects, process inefficiencies, or safety hazards. The Rosemount 248 incorporates advanced signal processing algorithms and high-precision sensor interfaces to minimize measurement errors.SpecificationSensor Type2-wire, 3-wire, or 4-wire Pt100 RTDMeasurement range-200°C to +850°Caccuracy±0.1°C or ±0.18°FLong-term stability±0.05°C/yearSensor drift detectionSupports alarmCommunication protocolWirelessHARTRadio frequency band2.4 GHz ISM bandTransmit power10mW (10dBm)Company Profileabout usMain productKeRui (WeiFang) Automation Equipment Co., Ltd. is specialized in industrialautomation instrument development, production and sales, technical servicesand supporting equipment supply of specialized companies.

It receives control signals from a controller and compares them with the actual valve position.Flowmeter: A flowmeter is an instrument designed to measure the flow rate of liquids, gases, or steam within a pipeline or channel. Transmitter: A transmitter is a device that senses a physical parameter, like pressure, temperature, or level, and converts it into a standardized output signal, usually 4 - 20 mA DC or digital signals.
