Specification

SEODescription

The RL443 sensor is a high-precision RL443 temperature probe integrated into a robust RL443 industrial transmitter, designed for critical industrial applications such as oil and gas, chemical processing, and food production. It features dual-channel input for simultaneous temperature measurement and signal conditioning, supporting direct connectivity to PLCs, SCADA systems, and IoT modules via RS-485 or Modbus protocols. Operating within a wide voltage range of 12-36V DC and an extended temperature span of -40°C to +85°C, this transmitter ensures reliable performance in harsh environments. Its IP67-rated enclosure enhances durability, while advanced noise immunity minimizes signal interference. Key advantages include ±0.1% measurement accuracy and NEMA 4X compliance, though installation requires specialized calibration tools. The integrated sensor-probe design eliminates external signal conversion, reducing system complexity.
