Product Description

The KRLL-WTL-B213 sensor integrates a multi-functional wireless transmitter and data logger designed for industrial monitoring applications. Equipped with 2 analog inputs (0-10V/4-20mA) and 1 digital output, the WTL-B213 wireless transmitter supports direct connections to up to 4 external modules via its modular interface. It operates within a 10-30V DC range and functions reliably across -40°C to +85°C, suitable for harsh environments in oil/gas, chemical processing, and agriculture. The KRLL-B213 data logger features 128GB internal storage, LoRaWAN/Bluetooth 5.0 connectivity, and a 2.4-inch LCD display for real-time parameter tracking. With 3000mAh battery backup, it sustains 72-hour standalone operation. The sensor achieves 100m line-of-sight wireless range but has limited signal penetration in dense metallic structures. Key advantages include IP67 protection, ±0.1% measurement accuracy, and compatibility with MODBUS RTU protocols.
