In the dynamic landscape of industrial temperature monitoring, reliability, accuracy, and durability are non-negotiable. The LFW20 Armored Temperature Transmitter emerges as a game-changer, engineered to deliver consistent performance across the most demanding environments. Designed with cutting-edge technology and robust materials, this transmitter is tailored to meet the diverse needs of petroleum, chemical, heating, hydrology, HVAC, and other industrial sectors, ensuring precise temperature data collection for optimized operational efficiency.
Unmatched Durability & Corrosion Resistance
At the core of the LFW20’s resilience lies its superior construction. The protective tube and probe rod are crafted from high-quality 304 stainless steel through integrated processing, boasting exceptional corrosion resistance and mechanical strength. This design enables the transmitter to withstand harsh media such as corrosive liquids and gases (compatible with contact materials) while maintaining structural integrity, even in long-term continuous operation. The die-cast aluminum housing further enhances its durability, providing reliable protection against physical impacts and environmental wear. With an impressive IP65 protection level (achieved after complete electrical connection), the LFW20 is well-equipped to resist dust, moisture, and splashes, making it suitable for both indoor and outdoor industrial settings. Additionally, the transmitter features a reverse protection function, safeguarding internal components from electrical damage and extending its service life.
Precise Performance & Versatile Output
Accuracy is the cornerstone of the LFW20 Armored Temperature Transmitter. Equipped with a high-precision platinum resistance sensor, it delivers remarkable measurement accuracy of 0.25%FS or 0.5%FS, ensuring that critical temperature data is captured with minimal error. The transmitter covers a wide measuring range of -50~300°C (with customized options available), accommodating diverse industrial temperature monitoring needs—from low-temperature hydrology applications to high-heat chemical processes. To adapt to different system integrations, the LFW20 offers flexible output signal options, including 4-20mA (two-wire system), 0-10V (three-wire system), RS485/Modbus, PT100, and PT1000. It operates on a supply voltage of 15~35VDC, ensuring compatibility with standard industrial power systems for seamless installation. The transmitter performs reliably within a working environment of -40~85°C and 0~95%RH (no condensation), maintaining stability even in extreme temperature and humidity fluctuations.
Flexible Installation & Adaptable Design
The LFW20 is designed with versatility in mind, offering multiple installation methods to suit various working conditions. Users can choose between sleeved type and direct insert type, with a range of mounting options including fixed thread installations (G1/2 male, G1/4 male, M161.5 male, M201.5 male, M27*2 male) and clamp installation (50.5MM). This flexibility allows for easy integration into existing pipelines, tanks, or equipment without extensive modifications. Probe length can be customized to meet specific immersion depth requirements—standard options include 30mm, 50mm, 100mm, 150mm, 200mm, 250mm, 300mm, 400mm, and customized lengths for both sleeved and direct insert types. The transmitter also offers cold end configuration options: without cold end (15mm), 100mm cold end length, or customized cold end designs. For operating temperatures above 120°C, extending the cold end is recommended to ensure measurement accuracy, highlighting the product’s adaptability to varying thermal conditions.
Pressure & Flow Resistance Capabilities
Engineered to handle real-world industrial stress, the LFW20’s protective tube exhibits excellent pressure resistance. The pressure it can withstand varies with tube length—for example, a 6mm diameter, 1.0mm wall thickness tube can endure higher pressures at shorter immersion depths (up to 35MPa at 150mm immersion depth at 50°C). Additionally, the protective tube is designed to resist medium flow, with the maximum withstand flow rate adjusting based on insertion depth. This ensures stable performance even in high-pressure pipelines or fast-flowing media, making the LFW20 suitable for dynamic industrial processes.
Easy Wiring & Accessory Compatibility
The LFW20 features clear and straightforward wiring instructions for different output types, simplifying installation and reducing setup time. Whether using RS485, current output (two-wire), voltage output (three-wire), or PT100/PT1000 output, the color-coded wiring diagram ensures error-free connections. To enhance installation flexibility, a range of accessories is available for separate purchase, including integrated sleeves, staged welded rings, flat welded rings, clamp adapters, flange adapters, ferrule adapters, and ferrule tubes.
Customizable Configuration for Specific Needs
The LFW20 Armored Temperature Transmitter offers extensive customization through its intuitive order reference system. Users can select parameters such as output signal, accuracy grade, temperature range, wiring box type, installation method, protective tube presence, probe length, and cold end length to match their unique application requirements. For example, the model LFW20-A4-50-1-0-G2-0-L100-1 specifies a 4-20mA output, 0.5%FS accuracy, 0~200°C temperature range (with cold end), waterproof wiring box, G1/2 external thread installation, no protective sleeve, 100mm probe length, and 100mm cold end length. This level of customization ensures that the LFW20 can be tailored to virtually any industrial temperature monitoring scenario.
Conclusion
