In industrial environments like data centers, HVAC systems, buildings, and warehouses, accurate and stable temperature detection is critical to operational efficiency and safety. The LFW10 Temperature Transmitter from LEFOO stands out as a professional solution, combining high precision, flexible installation, and strong anti-interference capabilities to meet diverse industrial temperature monitoring needs.
Key Features: Designed for Industrial Reliability
The LFW10 series is engineered to excel in harsh industrial conditions, with features that prioritize performance and usability.
Superior Sensing Accuracy: Equipped with imported Heraeus Class A sensors (including PT1000, PT100, NTC20K, and NTC10K options), it delivers typical accuracy of ±0.2~0.5°C at 0/25°C. This ensures precise temperature data collection, minimizing errors in critical applications.
Flexible Installation & Output: Offering 5 installation methods (wall-mounted, duct, pipe, split, clamp) and 3 output modes (4~20mA current, 0~5VDC/0~10VDC voltage, thermal resistance), it adapts seamlessly to different installation scenarios and system integrations.
Robust Anti-Interference & Protection: Built to withstand shock, surges, electrostatic discharges, and group pulse voltages, it maintains stable performance in noisy industrial environments. With IP65 protection rating, CE certification, and RoHS compliance, it resists dust, water splashes, and meets global environmental standards.
Quick-Fit Design: Featuring spring screws and terminal connections, the transmitter enables fast installation and deployment. Its new industrial-style housing, paired with a stainless steel probe (Φ6mm), balances durability and ease of use.
Technical Specifications: Powering Consistent Performance
The LFW10’s technical parameters are tailored to industrial demands, ensuring reliability across a wide operating range.
Operating Environment: Functions in temperatures from -40°C to 70°C and 0~95% RH (non-condensing), suitable for both indoor and outdoor applications.
Power Supply & Load: Voltage-type models accept 15~35VDC/24VAC ±20%, while current-type models work with 18.5~35VDC (RL=500Ω) or 8.5~35VDC (RL=0Ω). Output loads are <500Ω (current type), ≥2KΩ (0~5VDC), and ≥3KΩ (0~10VDC).
Housing & Probe: Constructed with PC housing and a stainless steel probe, available in multiple lengths (65mm, 100mm, 150mm, 200mm, or custom) to fit different installation depths.
Wiring Flexibility: Supports 2-wire (current output) or 3-wire (voltage/thermal resistance output) configurations, with clear wiring instructions for easy setup.
Installation Guidelines: Ensuring Optimal Performance
Proper installation is key to the LFW10’s accuracy, with model-specific steps to maximize reliability.
Wall-Mounted (LFW10-1) & Split (LFW10-4): Mount the transmitter with the probe vertically downward. For outdoor use, avoid direct sunlight, rain, or strong winds, and secure the mounting box with two screws.
Duct (LFW10-2): Use flange accessories for installation. Drill a 7mm hole, fix the flange to the duct with screws, adjust the probe insertion depth, and seal the hole after installation.
Pipe (LFW10-3): Install with a G1/2 connection joint welded to the pipe. Ensure the joint is leak-proof under system pressure before attaching the transmitter.
Clamp (LFW10-5): Designed for circular pipes, use cable ties to secure the probe tightly to the pipe surface. Keep the contact area clean and rust-free for optimal heat transfer.
Application Scenarios: Versatile Temperature Monitoring
The LFW10 series is widely used in scenarios requiring reliable temperature detection, including:
Data center HVAC systems: Monitor server room temperatures to prevent overheating.
Commercial buildings: Regulate heating, ventilation, and air conditioning for comfort.
Warehouses: Protect temperature-sensitive goods (e.g., food, electronics) from extreme conditions.
Industrial pipelines: Track fluid temperatures in manufacturing and processing lines.
Model Selection: Customize to Your Needs
The LFW10 offers customizable options to match specific requirements, with model codes defining installation type, output mode, temperature range, and probe length. For example:
LFW10-2A412: Duct-type, 4~20mA output, 0~50°C range, 200mm probe.
Key notes: Voltage/current output models (V10, A4, V5) support custom temperature ranges (1-8), while thermal resistance models use range code 0. Split-type (LFW10-4) comes with 1m standard cable, with longer lengths available read more on request.
Whether you need a wall-mounted transmitter for a data center or a clamp-type sensor for industrial pipelines, the LFW10 Temperature Transmitter delivers the precision, durability, and flexibility required for industrial-grade temperature monitoring. With LEFOO’s commitment to quality and compliance, it’s a trusted choice for businesses worldwide.
