LFW70 Explosion-Proof Temperature Transmitter: Precision & Safety for Industrial Temperature Monitoring
In industrial environments where temperature measurement demands uncompromising accuracy, safety, and reliability—such as petroleum, chemical, power, and hydrology sectors—the LFW70 Explosion-Proof Temperature Transmitter emerges as a leading solution. Engineered with premium components, robust explosion-proof design, and versatile configurations, this transmitter delivers consistent performance in hazardous and harsh conditions, making it an indispensable tool for critical industrial processes.
Superior Safety & Durable Construction
Safety is paramount in high-risk industrial settings, and the LFW70 excels with its top-tier explosion-proof ratings:
Flameproof type: Ex db IIC T6 Gb
Flameproof dust type: Ex tb IIIC T80°C Db
Crafted with a die-cast aluminum shell and 304 stainless steel probe and casing, the transmitter boasts exceptional mechanical strength and resistance to corrosion—compatible with a wide range of liquids and gases (matching the contact material). It achieves an IP66 protection rating (when electrical connections are fully installed), shielding against dust, water jets, and harsh environmental elements. Additionally, the LFW70 is equipped with comprehensive protections: reverse connection, lightning strike, current limiting, and over-voltage safeguards, paired with industrial-grade anti-interference performance to ensure uninterrupted operation in complex electrical environments.
High Precision & Stable Performance
At the core of the LFW70 lies imported A-class platinum resistors, high-precision ADCs, and reference components—all meticulously calibrated and debugged to deliver unparalleled accuracy. The transmitter offers two accuracy grades: ±0.25% FS and ±0.5% FS, with minimal temperature drift and long-term stability, ensuring reliable data even over extended use.
It covers a flexible temperature measurement range of -50~300°C (with multiple predefined ranges and customized options available), adapting to diverse industrial needs. The high-definition LCD display (operational between -10~60°C) provides on-site visibility of temperature data, while supporting multi-parameter on-site settings for added convenience.
The probe’s performance is optimized for real-world conditions: pressure resistance varies with immersion depth (up to 35MPa at 150mm immersion) and the maximum medium flow velocity it can withstand adjusts with insertion depth (up to 30m/s at shorter depths), ensuring compatibility with dynamic industrial processes.
Versatile Configurations & Seamless Integration
Designed to fit diverse system requirements, the LFW70 offers extensive customization options for easy integration:
Output Signals: Choose from 4~20mA (2-wire), 4~20mA+HART (2-wire), 0-10V (3-wire), or RS485/Modbus—catering to analog and digital communication needs. Output load compatibility is optimized: ≤500Ω for current type and ≥10KΩ for voltage type.
Power Supply: Wide voltage range for flexibility—15-35VDC for voltage/RS485 models, and 9.5-35VDC (RL=0Ω) or 19.5-35VDC (RL=500Ω) for current-type models.
Installation Options: Multiple thread and mounting choices, including M20*1.5 male, G1/4 male, G1/2 male, or 50.5mm clamp—adapting to different pipeline and equipment setups. Optional protective tubes and customizable probe lengths (30mm to 500mm, or customized) further enhance versatility.
Cold End Configuration: Select models with or without a cold end (100mm standard or customized), with the cold end recommended for use temperatures above 120°C to ensure measurement accuracy.
Wide-Ranging Industrial Applications
The LFW70 Explosion-Proof Temperature Transmitter is tailored for demanding industrial scenarios, including:
Petroleum and petrochemical processing (hazardous environments with flammable gases/dust)
Power stations (boiler, pipeline, and equipment temperature monitoring)
Chemical manufacturing (corrosive media and high-temperature processes)
Hydrology and water treatment (liquid temperature measurement)
Industrial automation systems (process control and regulatory monitoring)
Its explosion-proof design, corrosion resistance, and flexible parameters make it suitable for both general industrial use and high-risk hazardous areas.
